Resin Cable Joints – Filoform Branch Cable Joints

Resin Cable Joints – Filoform

Cable joints used for the connection, repair and jointing of power cables in branch configuration. Resin cast branch cable joints can be used to joint polymeric (XLPE EPR), plastic and paper insulated (PILC) low voltage cables – cable joints can be uprated to suit 3.3kV cables.

Filoform cable joints are approved in accordance with the standard DIN EN 50393 (VDE 0278-393):2006-11.

Injection Moulded Shells

Rigid and very strong cable jointing shells with snap-lock design forming an excellent seal and preventing resin leakage.

Mechanical Connectors

Filoform mechanical connectors are included in the cable joint kit machined from either solid brass (tunnel type) or aluminium (shear bolt) and are suitable for either copper or aluminum conductors – stranded, solid, sectoral or fine stranded copper/aluminium cables.

Earth Braid

Earth braid provides significant advantages over “single wire type” and jubilee clip (worm-drive) earth continuity systems which can fail if poorly positioned within wire armour cores that have “spread”. The flat, soft braid ensures excellent electrical contact and is insulated for extra protection.

Constant Force Springs

Cable joints are subject to cyclical movement and expansion 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 armoring and the earth continuity braid.

Two-part resin

Filoform cable joint resin is suitable for LV-MV jointing of cables with excellent adhesion to PVC, XLPE, polythene, and paper cables. Resin is supplied in a 2-part easy mix packaging, ensuring both convenience and safety.

Customised LV Cable Joints

An electrical contractor contacted Thorne & Derrick International with a complex requirement to branch cable joint a 2 core 300sqmm cable onto 2 x single core 300sqmm cables. In summary, the cable joint had to accept 3 cables being cut but 4 cores in total with 2 connections inside the cable joint.

Utilising Filoform MB300 Resin Branch Cable Joint with Sicame connectors type MF1/3, T&D were able to complete the delivery of the 10 cable joints within 2-3 days.
