케이블글랜드 상세사양검토 사례

 

안녕하세요 TIATIP 입니다.

 

케이블글랜드 선정과 관련한 상세 사양을 다음과 같이 소개합니다.

 

1. Why Should You Specify Cable Glands?

 

How often have we heard:-
"We don't specify Cable Glands, as long as they have the relevant certification then it must be fit for purpose. We leave it to contractor to sort out. We are too busy concentrating on the high value, long lead time items to bother about such an insignificant value product.

 

In a recent paper presented at the Hazard Ex conference by a Senior Manager of CENELEC Standards Inspections, it was stated, "Resources should be directed at eliminating the following common faults:

  • Unauthorised modifications.
  • badly made-off or unsuitable cable entry devices.
  • Corrosion.

It went on to say that out of these three factors, the most common fault was bad installation of Cable Glands. The paper was specifically referring to maintenance procedures, but this could equally be applied to new installations.

Incorrect specification and installation combined with the lack of ability to inspect the Cable Gland in it's operable condition can cause equipment failure and corrosion of cable armour and braid. The safety risks inherent in this is incalculable, as is the consequential loss of production.

This statement alone should be enough reason why specification of Cable Glands is an important decision. Just relying on the fact that a Cable Gland has a certificate "fit for purpose" is not enough.

 

2. So What Should You Take Into Account When Specifying The Cable Gland?

Certification and Selection

Of course, it is vital that the correct Cable Gland is selected and is certified as appropriate for the hazardous area in which it is to be used. We provide technical information in our Cable Gland catalogue and also supply a Cable Gland selection software application to take the specifier step-by-step through the process of selection. If still in doubt our Technical Department has a team of experienced engineers to assist. But just relying on a Cable Gland that is certified for the type of protection that is required (e.g. "fit for purpose") is not enough.

Ingress Of Moisture

One of the most important features of a Cable Gland is elimination of moisture ingress, not only into the equipment, but also into the armour clamping area of the Cable Gland itself. Water ingress into this area has been shown to cause catastrophic corrosion of cable armour and braids, with the associated costs of new cabling and downtime. IP ratings give a guide to protection of water and dust ingress into the equipment but not necessarily into the Cable Gland itself.

DTS01

In 1991 Shell UK recognised that IP ratings are not necessarily sufficient to meet the harsh conditions found in many hazardous area installations and developed a far more demanding test DTS01 to eliminate water ingress under thermal cycling and deluge conditions. We have taken Shell's DTS01 test one step further and our DTS01 test certificate is extended to show no water ingress into the armour clamping area of the Cable Gland when fitted with a deluge seal. This is clearly an issue when specifying Cable Glands. Not all Cable Gland manufacturers test certificates cover ingress protection into the armour clamping area, nor do they cover the full operating temperature range for which they have been certified for use.

 

Seals

Cable Gland seals perform two functions:

  • Prevents the products of an explosion reaching the outside atmosphere if an explosion occurs inside the enclosure.
  • Stops water and dust ingress into the equipment and Cable Gland.

Seal Materials

Various seal materials are used by different Cable Gland manufacturers, but in general they fall into two categories:

  • Thermoset (TSE) These materials are cross-linked (vulcanised) during the moulding process with the application of heat and pressure. Once formed, they will not 'melt' and will exhibit optimum sealing properties over a wide range of temperatures.  
  • Thermoplastic (TPE) Although much cheaper to manufacture than TSE seals they 'melt' when heated and their sealing properties deteriorate as operating temperatures increase. Ideal for appliance feet, soft touch knobs and handles, they are not recommended for critical sealing applications.

TSE's on the other hand, are far more suitable for Cable Gland seals and are the only materials used by Hawke International in our range of compression and diaphragm Cable Gland seals. TSE's have better elastic properties over a wider range of temperatures, e.g.:

 

Compression set (recovery from deformation), the test is done usually at elevated temperatures and a test piece is squashed in a clamp by 25% of it's thickness, left in an oven for 3 days, at the end of which the sample is left to recover at ambient temperature. The difference between the original thickness and the new thickness (the ‘set’) is expressed as a percentage of the amount it was squashed by - a good TSE will show a compression set % of less than a 3rd of that shown by even the best TPE.

 

The ageing resistance of TSE's is better, particularly ozone, UV, oxidisation resistance and ‘weathering’ resistance. The chemical and oil resistance of TSE's can be infinitely better. The temperature resistance of TSE's is much better. For example, silicone TSE (used in Hawke's rear seals and in the 453/Universal diaphragm seal) has a maximum intermittent operating temperature of 300°C, whereas most TPE's soften appreciably at 100°C. Silicone will operate effectively at -60°C, whereas the best TPE works at -40°C. Flame resistance is better, silicone has the additional benefit of being low smoke and fume and zero halogen.

 

Cable Tolerances And Construction

Cable costs are significant in a hazardous area installation and we have seen moves to reduce costs by reducing specification and tolerances of the cables. Hawke International Cable Glands employ a rear sealing system with an extremely wide tolerance range, which takes into consideration variation in cable diameters along it's length and does away with the need to specify Cable Glands with special outer seals.

 

Cold Flow

There are also requirements for some cables to be flame-resistant or flame retardant in accordance with IEC 60331 and IEC 60332. Many of these cables exhibit ‘cold flow’ of the inner sheath bedding. That is, the material will flow away from pressure applied to it, such as that of a Cable Gland inner seal of the compression or displacement type, hence creating an inefficient seal. The code of practice EN 60079-14 : 1997 / IEC 60079-14 : 1996 Clause 9.1.3 notes clearly states that a Cable Gland employing a compression (displacement) seal should not be used on cable exhibiting "cold flow characteristics". Hawke's 501/453/Universal Cable Gland uses a diaphragm inner seal that complies with this requirement in the code of practice, in that it exerts minimal pressure on the cables inner sheath. It does not cause ‘cold flow’ but maintains IP and explosion requirements.

 

Correct Installation

Only training of the Cable Gland installer in the correct practice of installation can ensure that the Cable Gland will function correctly. Most reputable contractors ensure that their personnel have been fully trained and in many cases, it is a requirement that they hold a certificate from a recognised training authority such as CompEx. However, in some regions of the world, this is not so stringent, therefore it is important that the Cable Gland selected has been designed with ease of installation in mind, that every Cable Gland comes with detailed installation instructions and is easy to inspect at each stage of the installation operation. We have designed our Cable Glands with minimum components, ease, speed and simplicity of installation.

Safety Through Inspectability

Safety is of prime importance on hazardous area installations. Safety depends on many factors, some of which have already been discussed. Inspectability of equipment also plays a key part in safety. Can all the safety features of the Cable Gland be inspected, preferably easily? We have developed Cable Glands that answer Yes to this question. All our Cable Glands can be easily disassembled to allow visual inspection of the armour clamping arrangement. In addition the 501/453/Universal allows inspection of the inner seal on the cable sheath and the ICG 653/ Universal in the only barrier Cable Gland on the market that allows full inspection and if necessary, repair of the cured compound without destroying the Cable Gland. And finally the rear sealing arrangement and deluge seal can be inspected in their operable position.

 

3. Why You Should Specify Cable Glands

If you are interested in safety, reliability and the lowest lifetime cost through reduced downtime and loss of production of your plant, then you should take the time to consider specifying the features you require from your Cable Gland.

Specification

In summary, what key features during specification of Cable Glands should you be considering?

The most common fault experienced on hazardous area installations is incorrect selection and bad installation of Cable Glands.

  • Will a Cable Gland that is certified "fit for purpose" meet all your requirements?
  • There are necessary features that are not covered in the certification process. Does the Cable Gland meet your requirements for ingress of dust and moisture?
  • Does it have a test certificate covering the deluge requirements of DTS01 for ingress into the equipment and into the armour clamping arrangement of the Cable Gland?
  • Will the Cable Gland seals give long life and protection from water ingress under the typical heat cycling and operational conditions on site?
  • Are they produced from the best Thermoset (TSE) material?
  • Will the Cable Gland sealing range cope with the cable diameter tolerances without the need for special seals?
  • Is the Cable Gland suitable for use on cables that exhibit ‘cold flow’ characteristics and in line with the code of practice BS EN 60079-14 1997/IEC 60079-14 1996 Clause 9.1.3?
  • Is the Cable Gland fast and easy to install with minimum parts and clear assembly instructions?
  • Will the Cable Gland enhance safety on your site through ease of inspection?

Careful consideration should be paid to these issues as they are not taken into consideration during certification. A certificate does not mean they are fit for your purpose. Correct selection and specification of Cable Glands will reduce costs during initial installation and throughout the life of the installation.

Wiring Systems NEC

 

 

안녕하세요 TIATIP 입니다.

 

NEC (National Electrical Code) 에 준하는  위험지역에서의 연결방식에 대한 개요를 살펴봅니다.

 

Cable systems and accessories should be installed in positions that prevent them from being subject to mechanical damage, corrosion, chemical attack, heat and other detrimental environmental conditions. Selection of the wiring system and cable type must consider these influences and where exposure to such conditions are avoidable, protective measures such as minimising the risk of mechanical damage by the use of appropriate armoured cable types should be considered. The connection of cables and conduits to the electrical apparatus must be in accordance with the requirements of the relevant type of protection and installation rules.

 

National Electrical Code (NEC) Zone Wiring Methods

In Class I, Division 1 locations, the NEC permits the following wiring methods:

 

● Type MC cable, listed for use, with a gas / vapor tight continuous corrugated aluminum sheath, an overall jacket of suitable polymeric material, separate grounding conductors, in accordance with Sections 250- 122 and 501.10 of the NEC, and provided with termination fittings listed for the application, e.g. Hawke type 711 cable gland/connector.

● Type ITC cable, listed for use with a gas / vapor tight continuous aluminum sheath, an overall jacket of suitable polymeric material in accordance with Section 501.10 of the NEC and provided with termination fittings listed for the application, e.g. Hawke type 711 cable gland/connector.

●  Threaded rigid metal conduit, threaded steel intermediate metal conduit, or type MI cable with termination fittings approved for the location and in accordance with Section 501.10 of the NEC.

 

 

 

All boxes, fittings and joints must be explosion-proof.

 

In Class I, Division 2 locations, the NEC permits the following wiring methods:

 

● Type MC, MV, ITC, PLTC, TC or MI cable with approved termination fittings in accordance with Section 501.10 of the NEC.

 

● Threaded rigid metal conduit, threaded steel intermediate metal conduit.

 

● Non-incendive field wiring using any of the methods suitable for wiring in ordinary locations in accordance with Section 501.10 of the NEC.

 

Boxes, fittings and joints need not be explosion-proof except as required by the NEC code.

 

Cable Seals, Class 1, Division 1

Cables must be sealed at the termination. The sealing fitting, e.g. a barrier type cable gland, must provide a seal against the passage of gas or vapours through the fitting. Type MC cables with multi-conductors, a gas / vapour tight continuous corrugated aluminum sheath and an overall jacket with a suitable polymeric material must be sealed with an appropriate fitting, e.g. Hawke type 711, after removing the cables jacket and all other coverings so that the sealing compound surrounds each individual insulated conductor. Cables with twisted pairs and shielded cables require the removal of the shielded material or separation of the twisted pairs unless the fitting, e.g. cable gland, is an approved means which minimises the entrance of gases or vapours and prevents propagation of flame into the cable core. If the fitting complies with this requirement, there will be information provided in the fittings installation instructions detailing the means to achieve the seal. Additional testing may be required on the fitting and the style and type of cable to show compliance with the sealing requirements.

 

An NRTL approved cable sealing fitting e.g. barrier type cable gland, must be fitted onto cables where they enter explosion-proof enclosures.

 

 Further guidance is given in Section 501-5(d) of the NEC.

 

 

Cable Seals, Class 1, Division 2

Cables must be sealed at the point of entrance into enclosures that require to be approved for Class I locations. A sealing fitting must comply with the above criteria given in "Cable Seals, Class I, Division 1".

 

An NRTL approved cable sealing fitting e.g. barrier type cable gland, must be fitted onto cables that enter explosion-proof enclosures.

 

United States Coast Guard - Wiring Methods

Electrical installations in hazardous (classified) locations must comply with the general requirements of Section 43 of the IEEE standard 45 and either the NEC Articles 500 - 505 or IEC 60079 series publications.

 

In hazardous (classified) locations, the USCG 46 CFR Sub-Chapter J, permits the following wiring methods:

 

● Marine shipboard cables that are permitted for use, must meet all the requirements of either IEEE standard 45, IEC 60092-3 and the applicable flammability requirements. Cables constructed to IEC 60092-3 must meet with the flammability requirements of IEC 60332-3, Category A.

 

● Metal-clad (type MC) cables that are permitted for use, must have a continuous corrugated gas tight, vapour-tight, and water-tight sheath of aluminum or other suitable metal that is close fitting around the conductors and with fillers. The MC cable must have an overall jacket of an impervious PVC or thermoset material and be certified or listed to UL 1569.

 

For information on other wiring methods permitted and further information, refer to Subpart 111-60 of the USCG 46 CFR.

 

Each cable entry into explosion-protected equipment must be made with an appropriate fitting or cable gland that maintains the integrity of the equipment.

 

Cables with multi-conductors that enter explosion-proof enclosures, must be sealed with an appropriate fitting, e.g. barrier type cable gland, after removing the cables jacket and all other coverings so that the sealing compound surrounds each individual insulated conductor. Cables with twisted pairs and shielded cables require the removal of the shielded material or separation of the twisted pairs unless the fitting, e.g. barrier type cable gland, is an approved means which minimises the entrance of gases or vapours and prevents propagation of flame into the cable core. If the fitting complies with this requirement, there will be information provided in the fittings installation instructions detailing the means to achieve the seal. Additional testing may be required on the fitting, and the style and type of cable to show compliance with the sealing requirements.

 

The equipment grounding path should be carefully considered when using Shipboard Cables or type TC cables, as these may not inherently provide a grounding means. The armour of Shipboard Cables should be grounded but can not be used as the grounding conductor. An appropriate sized grounding conductor should be included in each cable.

 

American Petroleum Institute - Wiring Methods

안녕하세요 TIATIP 입니다.

 

Hawke(호크)의 IECEx Scheme에 대해 조금 살펴보겠습니다.

 

The objective of the IECEx Scheme is to facilitate international trade in electrical equipment intended for use in potentially explosive atmospheres by eliminating the need for multiple national certification.

 

The IECEx Scheme provides a means for manufacturers to obtain Certificates of Conformity that will be accepted at national level in all participating countries. A Certificate of Conformity may be obtained from any certification body accepted into the scheme. The objective of the IECEx Scheme is world-wide acceptance of one standard, one certificate, and one mark.

 

For the IEC scheme to achieve its objective, every applicable national standard will need to be identical to the corresponding IEC standard. A transition period will be necessary to allow time for participating IECEx Scheme countries to align their national standards with the IEC standards and work towards national acceptance of IECEx Certificates of Conformity and the IECEx mark.

CENELEC and IEC Degree of Protection, IP Code

 

안녕하세요 TIATIP 입니다.

 

Hawke(호크) 제품군에 대한 CENELEC, IEC Degree of Protection, IP Code 를 살펴봅니다.

 

The standards IEC/EN 60529 describes a system for classifying the degrees of protection provided by the enclosures of electrical equipment as follows:

The protection of the enclosure and the equipment inside against external influences or conditions, such as: mechanical impacts, corrosion, corrosive solvents, solar radiation, icing moisture (e.g. produced by condensation), and explosive atmospheres, are matters that should be dealt with by the relevant product standard.

There are additional and supplementary optional letters to the above coding; these designators are A, B, C & D and H, M, S & W, and further information can be found in the relevant standard(s).

Deluge Ingress Protection

On offshore facilities, equipment may be located in areas subject to emergency deluge systems. Equipment that has been evaluated as certified for use in hazardous areas may not be suitable for use in these locations. A testing method for electrical equipment to be installed in areas subject to deluge systems, DTS01, has been prepared by the Explosion and Fire Hazards Group of ERA Technology (now known as ITS) in collaboration with Shell UK Exploration and Production Ltd.

Testing includes:

 

 

Energising the equipment (where appropriate) for 60 minutes prior to the deluge test, then interrupting the electrical power at the start of the deluge test and resuming after 60 minutes until the completion of the deluge test.

 

Carrying out insulation resistance testing before and after pre-conditioning and after the deluge test, where applicable.

 

Carrying out pre-conditioning by exposure to vibration and thermal ageing at 90% relative humidity and at a temperature 20k above the equipments maximum service temperature and/or at least 80°C of any appropriate seals.

 

Carrying out deluge test using a deluge chamber fitted with deluge nozzles that apply a salt water solution deluge pressure within the range of 3.5 bar to 4.5 bar at a water temperature in the range of 5°C to 10°C for 3-hours.
