33kV/36kV heat shrink high voltage cable joint kits are complete with mechanical connectors  or compression crimp connectors  for cable jointing of polymeric (XLPE) insulated cables. SPS heat shrink joints for high voltage power cable jointing of XLPE insulated cables suit both unarmoured, copper wire screened (BS7870) and aluminium wire armoured (AWA), copper tape screened (BS6622) HV cables.


HV high voltage heat shrink cable joints for single core cables are tested and qualified as outlined in Cenelec standards HD 628 S1 and 629.1 S2 : 2006. This testing criteria encompasses VDE0279 and IEC60502 and following voltage classes for HV cable joints : 3.8/6.6 (7.2kV), 6.35/11 (12kV), 8.7/15 (17.5kV), 12.7/22 (24kV) and 19/33 (36kV).
 
Earthing 33kV Single Core XLPE Cables with Aluminium Wire Armours AWA
If single core aluminimum wire armoured (AWA) 33kV cables are earthed only at one end, a voltage will appear at the opposite end of the cable run - if both HV ends are earthed, circulating currents will be induced. The is determined by i) length of 33kV cable installation, ii) current in the cable conductor and frequency, iii) proximity of the other two 33kV cables, presuming HV cables are installed in trefoil formation and iv) mutual inductance per phase. On long 33kV cable runs potentially lethal over voltages can be induced and standard earthing methods do not provide adequate high voltage cable protection. A simple method to reduce or eliminate this effect is to divide the 33kV cable run into three equal sections and request the trained HV cable jointer install 33kV cross bond kits available from Thorne & Derrick UK.

33kV Cable Jointing, Laying & Installation of Heat Shrink Joints - Trench : 33kV single core cables laid direct underground into cable trench to form one three-phase 33kV circuit are generally laid touching in trefoil, bonded together by nylon cable ties. Ducted : 33kV single core cables installed into cable ducts to form a 33kV three-phase circuit should be installed with each core in an individual duct and with the ducts laid touching in trefoil. Cable duct groups should be bound together by cable ties at intervals of one metre - three 33kV single core cables can be installed in a single cable duct for short lengths (eg road crossings). The cable jointer or contractor should check to ensure compliance with regional DNO practice prior to 33kV cable jointing and installation.
