`Easy application
`
`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.

`EEC f NEE Installations Requirements
`
`Here are the general requirements for selection of cable glands for hazardous locations :-
`
`Tl'tese cud-as require that any cable for use III a Hazardous Location must firstly be penndted for use i."- that
`location, and secondly be tested and approved or listed foI the application. Consequently cable glands intended
`lot use in Hazardous Locations, must also ue tested and aopioved oi listed for use in a specified location, iii
`cortionctioit with a SpE-EI'iIE'El and approved or listed cable type.
