  • Application: 11kV Heat Shrink Cable Joints
  • Cable Type: BS6622 Single Core XLPE Insulated AWA Armoured Cables
  • Cable Jointer: Neill Burns HV/LV Cable Jointer at BICS Ltd
  • By: Dan Rapley (Shrink Polymer Systems – Manufacturer of LV / MV Cable Joints, Terminations, Cable Accessories)

Working alongside their Specialist Distributor Thorne & Derrick has enabled Shrink Polymer Systems to support them and their clients on UK and international LV MV HV Cable Jointing & Installation projects up to 33kV.

Thorne & Derrick based in the UK are leading suppliers LV MV HV Cable Jointing, Installation, Earthing, Substation & Electrical Equipment.

Collaborating together as a team we have been able to offer cable jointing guidance, solutions and provide an abundance of bespoke cable joint and splicing solutions for some very unique and non-standard cable combinations and constructions, including Okonite and flexible trailing joints for Protolon cables.

Our decades of experience through LV-HV cable accessory testing, product knowledge and assisting on site engineers and cable jointers has allowed us to discover and produce quality products to facilitate specific jointing applications for subsea power cables (inclusive of fibre optic cores), LSF fire resistant cables and BS/IEC standard XLPE, EPR, PILC, or PICAS medium/high voltage power cables – this includes trifurcating, transition and trifurcating-transition jointing kits for the connection of  modern technology polymeric insulated Triplex cables to traditional paper insulated lead covered cables (PILC).

Shrink Polymer Systems

Pictured below are 3 single phase Shrink Polymer Systems single core XLPE armoured 11kV cable joints installed in a very tight cable duct with confined space working and restricted working space for the jointer to position and set the cables prior to heat shrinking the joints.

Note the outer protection, heavy wall, heat shrink tubes have been fully shrunk to the outer cable sheath of the 11kV power cable with no raised or “unshrunk” edges.

There are no scorches or heating damage to the heat shrink outer sleeve demonstrating excellent flamework by the jointer when using the gas torch –  the flame must always be on the move never applying heat to the same area for too long.

The armour cage for the AWA has been neatly fitted to provide earth continuity of the cable armour using armour earth clamps.

The cable joint’s slim and short length design has assisted the cable jointer to enable the 11kV circuit to be jointed and installed between the two steel beams in challenging worksite conditions – trefoil cable cleats are installed to protect and restrain the 11kV cables in the event of a short circuit situation.

Neill had never used SPS cable joints before but is one of the many Jointers who have been able to benefit from Thorne and Derrick’s excellent customer service to be able to arrange “same day kit and despatch” of our heat shrink jointing products.
