Product Description

XLPE cable advantage:

XLPE cable have higher long-term working temperature and greater current rating, and under the condition of the same environment, XLPE cable may be reduced size (normal cross section) 1 or 2 class in comparison with paper and PVC cable. These are not only improving the quality and properties of products, but also reduce cables' production cost.

XLPE insulated power cable is used to transmit and distribute power for the power transmission and distribution system of 35kV or lower. It is generally applied in the fields of power, construction, mine, metallurgy, petrochemical industry and communication. It completely replaces the oil immersed paper insulated power cable and partiallyreplaces the PVC insulated power cable.

Construction from the Inner Part to the Exterior Part of the XLPE Insulated Power Cable
Copper or aluminum conductor
XLPE insulation
Copper tape or copper wire screen
Galvanized steel wire or tape armored
PVC or PE sheath
