Medium Voltage Cable Termination Procedure

Cable networks cannot be built without joining cables together and terminating them to equipment or overhead lines.

Medium voltage cable termination procedure.

All of our medium voltage terminations feature. T d distribute the most extensive range of hv high voltage cable joints terminations connectors from manufacturers including 3m prysmian nexans euromold elastimold pfisterer connex and shrink polymer systems. Be instructive for all involved in the construction and operation of medium voltage mv cable networks. Euromold provides a complete range of accessories for underground cables.

Medium voltage cable accessories according to the international standards en 50393 iec 60502 4 iec 61442 and hd 629. While every care is taken to ensure that the information contained in this publication is correct no legal responsibility. The long term reliability of the network therefore depends critically on both the cable and the accessories installed on it. If they are done improperly the cable could fault causing thousands of dollars worth of damage or even personal injury.

Craftsmanship is also a major factor of a termination. Verify that visible cable bends meet or exceed icea and manufacturer s minimum published bending radius. The termination is made from pre stretched rubber wrapped around a core. All terminations meet or exceed ieee 48 requirements.

Testing and commissioning of medium and high voltage cables consider visual and mechanical inspections electrical tests as well as comparing these. Premoulded epdm rubber connectors for cables and epoxy bushings for transformers and switchgear as well as a large range of cold shrinkable terminations and joints from 12 to 42 kv. When the various layers are removed cuts should extend only partially. Repair of damaged outer jacket of lv cable shall be as per manufacturer s instructions per nec 110 3.

Medium high voltage cable preparation it is necessary to begin with a good cable end. When the core is removed the rubber provides a constant inward pressure on the cable forming a seal which expands and contracts with variations in temperature and load. Heat shrink cold shrink push on and slip over cable accessories enable the jointing terminating and connection of 11kv 33kv and 66kv 132kv cables to oil air or gas insulated. For this reason it is common practice to cut off a portion of cable after pulling to assure an undamaged end.

Repeat the installation activities procedure on other portion of medium voltage cable with damaged outer jacket.
