What goes into a good cable joint?

CTL ElectricalCTL ElectricalCTL ElectricalCTL ElectricalInjection Moulded Shells
Rigid and very strong, their snap-lock design forms an excellent seal and prevents egress of resin.

Mechanical Connectors
Our MC1/0 to MC1/3 connectors have been especially designed to accept the same range of cable sizes as the CM0 to CM3 LV cable joints they are supplied with. Machined from solid brass, they are suitable for either copper or aluminium conductors. Two Allen screws for each core ensure a sound electrical performance and an Allen key is also provided with each kit to ensure that everything needed to join a cable is included in the one box (CM and CB “+C” ranges). The connector range is complemented with larger aluminium alloy connectors (see page 11).

Earth Braid
Offers significant advantages over “single wire type” earth continuity systems, which can fail if poorly positioned within wire armour cores that have “spread”. The flat, soft braid ensures good electrical contact and is insulated for extra protection.

Constant Force Springs
Cable joints move and expand due to earth shift and heat from electrical current. Constant force springs react to this movement and maintain a sound electrical connection between the steel wire armouring and the earth continuity braid.

Core separators
Provide safe separation of cores and connectors.

Two-part resin
CTL’s long-proven resin formula is of such quality that it is equally suitable for both LV and MV applications and provides excellent adhesion to PVC, XLPE, polythene and paper cables. It is supplied in two-part easy-mix packaging, ensuring both convenience and safety.

CTL joints are supplied in especially robust and rigid boxes to withstand stacking both in warehouses and in pallets. These boxes are also popular with jointers since they can be used as “mini workbenches”.

Detailed, clear and concise instruction sheets, mostly printed in full colour, ensure there is no ambiguity about safe jointing procedures.

Breadth of range
There are few, if any, combinations of power cables that CTL cannot join. We offer over 400 variations of resin cable joints including special versions for mines & quarries; oil & petrochem; telecom & control; cathodic protection. These utilise both resin and heatshrink technologies and are supplied for both LV and MV applications.
