Cable Joints
HV cable joints are suitable for medium/high voltage (MV-HV) 11kV 3 core XLPE, EPR and PILC/PICAS insulated cables.
Heat shrink cable joints suit 11kV cables with 35sqmm – 300sqmm 3 core conductors (copper or aluminium) – this includes steel wire armoured (SWA) cables with XLPE insulation and wire braided cables with EPR insulation.
Shrink Polymer Systems 11kV cable joints are tested to CENELEC standards HD 628 S1 and 629.1 S2:2006 encompassing VDE 0278 and IEC 60502 – heat shrink joints are smooth profile design ideal for confined spaces, direct burial underground in cable trench and vertical jointing of cables for medium/high voltage cables.
Resin Joints – High Voltage & Hazardous Area
11kV joints for 3 core power cables are also available with optional resin and shell encapsulation for additional mechanical protection for underground cable joints.
For jointing 11kV medium/high voltage cables in hazardous areas, including Zone 1 & Zone 2 according to ATEX Directive, where soil conditions or atmospheric conditions are contaminated with corrosive hydrocarbons and flammable gases the heat shrink or cold shrink cable joints can be supplied with flame and hydro carbon resistant Scotchcast 1402FR resin.
Cable Joints – LV MV HV joints suitable for all cable construction, arrangement and installation requirements from 6.6kV, 11kV up to 33kV.
