Description

Concentric cable is mainly  used as electric  service entrance from the power distribution network until the meter panel, and as feeder cable from the meters panel until the panel or general distribution panel, just as it is specified in the National Electrical Code. 

This type of conductor can be used in dry and wet places, directly buried or outdoors,its maximum temperature of operation is 70 degree (PVC or PE insulation  ) or  90 degree(XLPE Insulation ) and its voltage of service for all the applications is 600V.

PACKING

Our electrical cable export packing is specially made to ensure that the quality of the products will be not affected during the transportation. Our electrical cable is using electrical cable wheel for the packing, the wheel can be all steel, steel frame and fumigated wood, or fumigated wooden cases. We are using different packing for different length of the cable, to ensure there  will be no problem during the delivery of the products.

      1. If the diameter of the wheel is longer than 2 meters, we are using all steel wheel to pack the products

      2. If the diameter of the wheel is between 1.4meters to 1.8meters, we are using steel frame and fumigated wood to pack the products.

      3. If the diameter of the wheel is less than 1.4meters, we will use the fumigated wooden wheel to pack the products

      4. For the packing of the electrical wires and small quantity of cables, we will use the fumigated wooden box to pack.
