0.6/1kv XLPE insulated power cable
Summary
XLPE insulated power cable has a lot of advantages over paper insulated and PVC insulated cable. XLPE cable has high electric strength, mechanical strength, environmental stress resisting, corrosion, and simple construction.
the XLPE insulated power cable is used for transmit and distribute power. which is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication.
