Copper core cross-linked PE insulated overhead cables
|
When overhead fixed lying is carried out, flexible copper core products are used as transformers' down lead. When cables are set up, it should be considered that cables and trees shall be maintained in a certain distance, and when the cable is in operation, cables are allowed to contact trees frequently.
