Thorne & Derrick, a leading UK based Specialist Distributor of LV HV Jointing, Earthing, Substation & Electrical Eqpt for use in Explosive Atmospheres, are proud to present product innovation from CMPÂ – the world-leading manufacturer of cable glands for the safe termination and sealing of cables in potentially explosive atmospheres.
This Guest Article contributed by CMP describes their cable sealing solutions for hazardous areas featuring their Triton T3CDS cable glands and RapidEx barrier cable glands.
Triton CDS
Right-First-Time Installation
Triton T3CDS cable glands deliver a unique concept in cable sealing techniques incorporating the Compensating Displacement Seal system (CDS).
This concept provides effective sealing on the cable inner sheath utilizing a proven reliable and robust flameproof seal.
The CDS system is activated at the critical cable sealing point, protecting the inner sheath from any excess force. The force is instead transferred and absorbed by the internal compensator in the CDS system, allowing metal-to-metal tightening every time regardless of cable diameter.

CMP Displacement Seal
The below illustrations demonstrate how CMP’s displacement seal reduces indentation on the cable – the installation is independently controlled by the user during installation of the cable gland to achieve secure flameproof sealing and wire armour termination.

RapidEx – The Original Sealing Solution for Barrier Cable Glands
A barrier gland is a cable gland that provides an effective seal around the individual cores of a cable to maintain the flameproof integrity of Exd Explosion Protected equipment.
Traditional barrier cable glands employing an epoxy-cured clay-based sealing compound, have been used in the industry for many years, to provide effective explosion protection.
However, a certain degree of skill is required with this traditional installation process and the risk of voids increases with the number of cable cores.
Multi-core cable requires the highest degree of competence and a long installation time to ensure a void-free, safe installation.
Revolutionary Rapidex | RapidEx is a revolutionary liquid resin sealing solution for barrier cable glands and unions, for use in conjunction with flameproof or explosion-proof enclosures.
In 2012, CMP introduced RapidEx to the market.
RapidEx is a liquid-pour, fast-curing, liquid resin barrier seal that installs in seconds and cures in minutes. The barrier gland has since been installed on a number of major global projects for safe and secure sealing of cables in explosive atmosphere industries including oil, gas and petrochemicals.
Its unique formula begins with a low viscosity liquid that flows into the cable interstices, completely surrounding the cable conductors, and in the process displacing the air from the cable gland’s sealing chamber ensuring the perfect seal.
The viscosity increases and completely cures in less than 40 minutes (at 20°C / 68°F).
- Enhances reliability, reduces risk
- Delivers unprecedented reliability
- Minimises installation time
- Clean and easy to use
CMP RapidEx is certified for use in explosive atmospheres with global certification including approval under ATEX, NEC, CEC and IEC installation codes, and is available with a series of CMP barrier cable glands and unions.

NEW Product Launch
717 Stopper Plug
CMP 717 nylon stopper plug range is available for use in industrial applications (717) or explosive atmospheres (717e).
The 717 range of stopper plugs allow customers to ‘blank’ unused cable entries and are manufactured from a unique polymer; providing a combination of strength and durability over the longer term – or simply providing a temporary solution.
Designed to reduce cost and installation time, both the 717 and the 717e feature a universal installation design, comprising a hex-head for spanners, a flat screwdriver and allen key recess. Both products are tested to IP66, IP67, IP68 & IP69(K) without the need of an additional entry thread seal, reducing time as well as cost of installation.
The interface between the stopper plug and its associated enclosure / cable entry does not require additional sealing to achieve ingress protection (IP) ratings higher than IP54.
The minimum protection level is IP54 for explosive gas atmospheres and IP6X for explosive dust atmospheres.
