DWZN-YJ(F)E
|
( irradiated) XLPE insulated low-smoke halogen-free polyolefin sheathed flame-retardant power cable
|
For a high flame retardant and fire cable in cable release smoke less, gas corrosion performance is low, able to bear external mechanical forces in the transmission and distribution line. |
