4.0 GENERAL TECHNICAL REQUIREMENT<br />
4.1 Conductor<br />
4.1.1 The conductor shall be made from electrically pure Aluminium wires. The<br />
wires shall be stranded together and compacted.<br />
4.1.2 The conductor shall be circular in shape.<br />
4.2 Conductor Shielding<br />
An extruded semi conducting compound shall be provided on the<br />
conductor to provide a smooth surface & eliminate electrical stress<br />
concentration.<br />
4.3 Insulation<br />
The core insulation shall be with Cross linked polyethylene unfilled<br />
insulation compound. It shall be free from voids and shall withstand all<br />
mechanical and thermal stresses under steady state & transient operating<br />
conditions. The insulation shall be applied by triple extrusion process.<br />
4.4 Insulation Shielding<br />
The insulation shielding shall consist of non-metallic semi-conducting<br />
compound in combination with non-metallic screening of copper. It shall<br />
be possible to strip the insulation screening without applying heat. The<br />
screen shall be capable to carry single line to ground fault current for a<br />
duration of one second.<br />
4.5 The conductor screen and XLPE insulation screen shall all be extruded in<br />
one operation by extrusion to ensure perfect bonding.<br />
4.6 Armouring<br />
G.I. Flat street wire armouring shall be provided over the inner sheath.
