Medium Voltage Power Cable
Medium Voltage Power Cable
Applications
The cables are mainly used for:
· Indoors and in cable ducts
· Outdoors,underground and in water
· in power supply stations
· Transformer stations
· Industrial Plants
Due to the good laying characteristic, this cable can also be installed in difficult line guideways.
The inner conducting layer between the conductor and the XLPE insulation and the firmly bonded outer conducting layer on the XLPE insulation assures a construction free of partial discharges with high operational reliabilities.

Details
AL/XLPE/CTS/PVC Cable
Medium voltage single core cable is suitable for use in power networks, in fixed installation outdoors in cable ducts or directly in the ground. Cable operational stability is enhanced because of very low dielectric loss factor, excellent insulation property of XLPE and firm bonding with conductor screen and insulation screen of semi-conductive material (extruded in one process), which makes it widely used in transformer stations, electric power plants and industrial plants.
