Product Description

Medium Voltage Copper Conductor XLPE Insulated PE Sheathed 3 Core Power Cable

Application
XLPE 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. Laying indoors, in tunnel, fixed on the bracket, pipe and buried in the soil, the cable cannot bear external mechanical forces.

Standard
IEC60502,IEC 60228,IEC60332, BS 5467, BS 6622, IS 1554, IS 7098 and ICEA S-66-524 etc.
Hongda Cable can also design and produce for special application requirement.

Conductor Screen: Extruded semi-conductive compound
Insulation: XLPE (cross-linked polyethylene) rated at 90°C
Insulation Screen: Extruded semi-conductive compound
Metallic Screen: copper tape or a concentric layer of copper wires
