Copper Conductor Material and Underground Application Electrical Power Cable

0.6/1kV XLPE Insulated Low Voltage Power Cable
1  Main Application
 
XLPE(Cross linked polyethylene) insulated cable functions well for electricity transmission and distribution lines for its excellent electrical and physical properties, including the advantage of simplicity in construction, lightness in weight; convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties.
