Medium voltage cable termination procedure.

Iii termination but without a few of the time saving features that the qt iii termination posesses. For this reason it is common practice to cut off a portion of cable after pulling to assure an undamaged end. Medium high voltage cable preparation it is necessary to begin with a good cable end. Terminations are a very important part of a cable system.

Repair of damaged outer jacket of lv cable shall be as per manufacturer s instructions per nec 110 3. If they are done improperly the cable could fault causing thousands of dollars worth of damage or even personal injury. The termination is made from pre stretched rubber wrapped around a core.

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. 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. While every care is taken to ensure that the information contained in this publication is correct no legal responsibility.

Repeat the installation activities procedure on other portion of medium voltage cable with damaged outer jacket. All low voltage cables shall be installed as per the company requirement. 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. Verify that visible cable bends meet or exceed icea and manufacturer s minimum published bending radius.

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. Euromold provides a complete range of accessories for underground cables. A key to good cable preparation is the use of sharp high quality tools. Be instructive for all involved in the construction and operation of medium voltage mv cable networks.

Testing and commissioning of medium and high voltage cables consider visual and mechanical inspections electrical tests as well as comparing these. Testing procedure for 3 core 70 sq mm copper mv.
