Low Voltage Electrical Cables
1 kV power cable with XLPE insulated aluminium conductors
Low-voltage cable lines are widely used in low-voltage power distribution systems because of their reliable operation, lack of poles, lack of ground occupation, lack of unsightliness, and less influence from the outside world.
