XLPE Insulated PVC Sheathed Non-armored MV Cable

Tianjin Beida is a China XLPE Insulated PVC Sheathed Non-armored MV Cable manufacturer and supplier. These cables are widely used in power systems. It serves as the "power artery" of urban power grids, industrial and mining enterprises and high-rise buildings, and it can transmit 10,35 kV high-voltage electricity from substations to various power terminals.

Selection of medium voltage cables

1. Select according to voltage level, commonly used cable level is 3.6/6 kV， 6/10 kV， 8.7/15kV，12/20 kV，18/30 kV；26/35 kV

2. Select according to the power of the equipment or the current transmitted, calculate the current that the equipment needs to use according to the power of the equipment, and then select according to the cable ampacity table. In addition, it is necessary to calculate the voltage drop of the cable using the length of the cable, and the voltage drop cannot exceed 5%.
