`
`This comparison shows the time
`required to mix and apply barrier
`materials on a range of multi conductor
`cables, using either Clay Based Epoxy
`Compound or RapidEx Liquid Pour
`Resin. This outlines the fact that the
`application of the RapidEx liquid pour
`resin is easier than traditional methods.
`
`faster curing
`
`One of the many advantages of using the RapidEx
`liquid pour resin is the time saved in the completion of
`the cable installation, due to the fast curing formula.
`
`This means that not only is the installation inherently
`more reliable, but an installation cost saving can also
`be made.

`
`Inspection requirements
`As is the case with all cable glands intended for use
`in hazardous areas, barrier glands will be subjected to
`inspection from time to time. Inspection requirements
`may vary from site to site, or territory to territory,
`but the basis for inspection is usually determined
`by standards or client policy and procedures. In IEC
`60079-17 “Electrical installations, inspection and
`maintenance” three grades of inspection exist, which
`are detailed as follows :-
`V - Visual Inspection (External visual examination),
`C - Close Inspection (Removal of shroud, if applicable,
`for external visual examination),
`D - Detailed Inspection (Opening / Disassembly of
`cable gland for internal examination).
`
`When periodic detailed inspections are carried out on
`Flameproof (Ex d) equipment, part of the inspection
`requirement is to check that the flange dimensions
`of flanged joint gaps are within maximum values
`permitted by IEC 60079-1. It is also necessary to
`check that joint surfaces are clean and undamaged.
`This inspection standard also requires that stopping
`boxes and filling boxes are checked to ensure they are
`correctly filled. It would normally be possible to check
`that a cable sealing box or stopper box was correctly
`filled via a dedicated port that was provided with
`a removable flameproof plug. The existence of this
`“stopper plug” catered for subsequent inspections.
`When it comes to barrier glands there are no
`specific checks that can be easily enacted on site
`that guarantees a compound barrier gland is filled
`correctly. The RapidEx liquid pour solution provided
`by CMP eliminates this risk and delivers a more
`reliable installation.

`
`CEC / NEC Installations Requirements
`Here are the general requirements for selection of cable glands for hazardous locations :-
`These codes require that any cable for use in = Hazardous Location must firstly be permitted for Use in that
`lacation, and secondly be tested and approved or listed for the application. Consequently cable glands intended
`lor Use in Hazardous Locations, must also be tested and approved or listed for use in @ specified location, in
`conjunction with a specified and approved orlisted cable type.
`
`Cable Wiring Methods - Class |, Division 2
`& Zone 2
`
`Complete Jists of surtable cable types for use in
`hazardous areas can be found by consulting the
`current NEC and CEC handbooks, Additional
`information for camman cable types approved far
`offshore installations can be found by consulting
`section 43 of IEEE Standard 45 and API RPI 14F & 14Pe
`
`As a general rule, cables permitted and listed for
`use in Class | Division 1 and Zone 1, and listed non
`armored cables can be used in Class | Division 2 and
`fone 2 hazardous locations.eg, Type TC (Tray Catile),
`Interlacked Armor cables
`
`Cable Seals, Class | Division 2 & Zone 2
`
`Where cables enter Class! Division 2 endiosures,
`ihe cable must be sealed if the enclosure contains
`any arcing or sparking devices or if the enclosure
`is explosion proof. In such cases a sealing fitting or
`Barner gland ta UL 2225 of CSA 22.2, Class | Division
`Tor Division 2 must be used, Where the enclosure
`does not contain any arcing of sparking devices and
`the enclosure is NOT explosion proof, a cable is not
`required ta be sealed at the point of entry:
`In such
`cases 2listed cable gland or cable cannector withaul
`compound sealing function may be Used, eg. TC,
`TMC2, TSCD5 of C2KA cable connectors. Similarly for
`Class | Zone 1 & Zone 2 AEx e enclosures (Increased
`Safety), a non sealing fitting approved for use in this
`application can be used, &g. TC, TMC2, TSCDS or
`C2k% cable glands.
`
`Note: Non ‘Sealing’ type glands are restricted ta
`Diwisian 2 & Zone 2 equipment that does nat contain
`an ignition source of ta Zone 1 AEx € equipment, If the
`enclosure 6 required to be explosion proof under NEC
`conditions an approved barter seal must be used.
`
`Cable Wiring Methods
`The use of flexible cables in North America has
`provided industry with a wide choice of wiring
`methods. However, there are differences between
`the NEC and CEC for cables suitable for use ir
`Hazardous areas and extreme care should be taken
`during the selection process. e. A cable type may
