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 CMP – 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 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.

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.

Additional Cable Sealing Benefits
Cable Glands | The T3CDS hazardous area cable gland, manufactured by CMP, supplied in brass as specified by the end customer allows for quick installation and ease of inspection throughout its life on site.

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).
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.

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.
Thorne & Derrick provide competitive prices and fast delivery from stocks for the complete range of CMP cable glands for connecting, terminating and sealing all types of LV MV HV cables located in industrial non-hazardous, hazardous area zones and medium/high voltage electrical systems.
As well as cable glands, CMP offer a range of cable cleats that are designed for a variety of industries including the data centre, renewable energy, utility and rail market where high performance and a compact design of cable cleat is critical for the retention of cables in the event of a short circuit fault situation.

BBC Cellpack manufacture cable connection systems and accessories for low and medium voltage power systems. This has given them a unique know-how, covering the entire range from preparation of raw materials, specification of cast resins and gels, creating the formulas for the plastics, to installation and packaging of our cable accessories.
In the photograph below the medium voltage cable end has been stripped and prepared prior to termination – the cable end is showing the different layers and also the graphite coating on the XLPE insulation not removed. Graphite coated semicon layers consist of a paper/cloth layer forming the semicon layer, which is graphite (conductive) coated and this graphite powder remains attached to the cable insulation after paper/cloth removal. The graphite must be cleaned using an approved cable cleaning solution suitable for medium voltage cable insulation ensuring no residues remain.
Cable jointing tools manufactured by Alroc for the removal and stripping of outer cable sheath, semi conductor screen and insulation from LV, MV, HV and EHV power cables.
Cable screen stripping tools are available to remove bonded semi-conductor screens from MV-HV cables and screen scoring tools available for removing peelable semi-conductor screening from medium/high voltage cables.
Cable preparation is essential to the performance and stability of MV-HV cable joints and terminations – if cables are under prepared using sub-standard tools or basic hand tools then the risk incidence of cable failure is increased.
Alroc tools have been developed in co-operation with world leading manufacturers of Medium, High & Extra High Voltage Cables to ensure their electrical performance is not comprised by poor workmanship and failure to use precision engineered, designed for purpose cable jointing tools.

CD980s Extendable Cable Drum Trailer
CD980S
SEB CD980S is a cable drum trailer suitable for use “off road” with the ability to handle up to 5000mm diameter cable drums – cable drum trailers ensure safe loading, transportation and laying of LV, MV, HV & EHV cable from drums into a cable trench with a payload up to 48,000Kgs.
CD980s extendable cable drum trailer capable of off loading and carrying 50T Drums of cable. The SEB CD980S trailer concept and design which was a joint initiative between the Energy Ops Teams and Magnor Plant, Morgan Sindall’s in-house Plant Business.
The cable drum trailer successfully off loaded a 45T drum, one of 109 drums required to complete the project.
The cable trailer design has removed the need for cranes on site, no lift plans, no spindles for the trailers, all in all a much safer and cost-effective way of off loading and transporting large drums of medium and high voltage power cable.
It was three years in the design and making but a great result and real game changer for the industry, another first for Morgan Sindall.

North Sea Link Interconnector Project
This is the first Blog in a series by Nexans explaining how their subsea solutions are helping to meet global demand.
The North Sea Link Interconnector project is a huge and ambitious project that involves cooperation, innovation, engineering, and lots of planning. This summer, Nexans began the major installation operations in Western Norway.
The Nexans’ land high voltage cables arrived for the North Sea Link project in Halden.
Nexans have been awarded a turnkey project covering 2x250km of 525kV HVDC subsea and land cables.
This interconnector link will be the longest subsea electricity link in the world. In the below video the five high voltage cables will be installed at the Kvilldal converter station.
Due to the logistics of this complex project the land cables must be transported first.
The vessel will now travel to the town of Sand in the western part of Norway to unload the cables.
