Conductor: Class 1/2 annealed bare copper solid or strands. This wires are formed into final conductor in the stranding machines under strict quality surveillance.

Insulation: Cross linked polyethylene compound or PVC is insulated over the conductors by extrusion process.The raw materials and thicknesses of Insulation are maintained as per standards and conform to IEC60502/BS7870 Standards as the case may be.

Xlpe Insulated Power Cable are identified either by colour or by numbers as follows:
No. of cores Identification
Old Colour coding New Colour coding as per BS
1 Red or Black Brown or Blue
2 Red & Black Brown, Blue
3 Red, Yellow Blue Brown, Black, Grey
4 Red, Yellow, Blue & Black Blue, Brown, Black, Grey
5 Red, Yellow, Blue, Black, Y/G Blue, Brown, Black, Grey & Y/G

Armour : When armouring is required, the armour consists of single layer of galvanised steel wires/galvanized steel tapes.
The armour is applied helically as per standards.
Single core cables are armoured with Aluminium Wires or Copper wires based on requirement.

Outersheath : Standard cables are manufactured with Extruded black PVC. Outersheath is embossed or printed with the information required by relevant standards.
Special FR, FRLS, FRRT, LSF, MDPE compounds are used for outersheathing of cables, to suit customer’s specific requirements.

Operating characteristics

1, Long-term allowable operating temperature of cable conductor ≤70°C
2, Highest working temperature of cable in case of short circuit (the longest lasting time is not over 5s): ≤300mm2 cable conductor ≤160°C, ≥300 mm2 cable conductor≤ 140°C.
3, The laying temperature should over 0℃,Permissible bending radius of cable:for single core unarmored cable, should be no less than 20 times of it’s outer diameter ; for multi-core unarmored cable, should be no less than 15 times of it’s outer diameter
4, With flame-retardant property,ZA,ZB,ZC,ZD are 4 types
5, The product is applicable for AC 50 Hz transmission and distribution lines with rated voltage of 0.6/1KV
