Screend Power Medium Voltage Cable Fire resistant Polyvinyl Chloride Sheath
MEDIUM VOLTAGE CABLE STANDARD
International: IEC60502-2
National: GB/T 12706.1-2008
Other standards: such as BS, DIN and ICEA, design & manufacture special power cable according to customer’s special request.
MEDIUM VOLTAGE CABLE CONSTRUCTION
Construction: Compacted stranded circular copper conductor, extruded semi-conducting compound as conductor screen, cross-linked polyethylene(XLPE) insulation, semi-conducting compound as insulation screen, copper tape or combination of copper wire and tape as metallic screen, three cores assembled together with non-hygroscopic polypropylene filler, wrapped with binder tape, PVC inner covering as armor bedding, double steel tape armored, PVC or PE outer sheath.
MEDIUM VOLTAGE CABLE APPLICATION
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel, in cable trench, or direct in ground, able to bear external mechanical force, but unable to bear large pulling force.
MEDIUM VOLTAGE CABLE CHARACTERISTICS
Max. permissible continuous operating temperature of conductor: 90 °C
The bending radius of cable is recommended as following:
