To discuss your requirements or to learn more about the provision of LV-HV Cable Installation, Civil Engineering & Groundworks Services from BERC Ltd you can contact Darren on 07501025337.
The Jointers used Alroc PG pliers to remove the outer sheath from the medium voltage power cables – a specialist cable jointing tool manufactured by Boddingtons was used to remove the semicon prior to the connection and termination of the 33kV cables (630sqmm) into Siemens switchgear using Pfisterer CONNEX type separable connectors and Sicame terminations onto the outdoor substation busbars. Finally, a circuit of medium voltage 33kV cables (240sqmm) were terminated onto the busbars and connected using MV CONNEX Connectors onto the Auxiliary Transformer and the Neutral Earthing Resistor (NERs) manufactured by Cressall Resistors.
MV Cable Jointers with SPEN Authorisation up to 33kV
SPEN have 30,000 substations (1 for every 100 customers), 40,000km overhead lines and 65,000km underground cables – operating in 3 of the UK’s largest cities (Liverpool, Glasgow & Edinburgh) accounting for 1.6m (43%) of their customers, delivering LV-HV power to significant rural areas (North Wales, Scottish Borders and Dumfries & Galloway).

Wind Farm Connections for MV Cables
Nexans Euromold Terminations
Nexans Australmold Sales Manager, Johnothan Bocor says “reduced installation time, no flame, EHV design technology, hydrophobic, solid and robust cable terminations. The Nexans Euromold slip-on terminations meet the demands for outdoor and indoor installations for medium voltage power systems. These installations are 33kV wind farm substations in Victoria, Australia and you could not ask for a harsher outdoor environment and electrical system with cyclic electrical loads. The indoor profile is compact catering for all modern switchgear type installations. The size range for 33kV is 50sqmm to 800sqmm, the outdoor installations in the images are on 33kV 800sqmm cable and the indoor installations are on 33kV 185sqmm and 800sqmm. Pristine installations and excellent quality of work, a testament to the jointers installing them, they look fantastic.”
Shown in the last image is the Ripley SCS semi-con scoring tool which was used during this cable termination installation.
