IV) TECHNICAL SPECIFICATIONS FOR L.T. XLPE POWER<br />
CABLE<br />
1.0 GENERAL<br />
The cables shall be suitable for laying in racks, ducts, trenched, conduits<br />
and underground buried installation with uncontrolled back fill and<br />
chances of flooding by water.<br />
They shall be designed to withstand all mechanical electrical and thermal<br />
stresses under steady state and transient operating conditions. The XLPE<br />
cables shall withstand without damage a three-phase fault current of at<br />
least 26.2 kA for at least 0.5 second. The armour for these power cables<br />
shall be capable of carrying 26.2 kA for at least 0.5 second without<br />
exceeding the maximum allowable temperature of outer sheath.<br />
The XLPE insulated cables shall be capable of withstanding a conductor<br />
temperature of 250 degree C during a short circuit without any damage.<br />
The aluminium wires unsed for manufacturing the cables shall be true<br />
circular in shape before stranding and shall be uniformly good quality, free<br />
from defects. All aluminium used in the cables shall be of H2 grade.<br />
The fillers and inner sheath shall be of non- hygroscopic, fire retardant<br />
material, shall be softer then insulation and outer sheath shall be suitable<br />
for the operating temperatures of the cable.<br />
Progressive sequential marking of the length of cable in meters at every<br />
one meter shall be provided on the outer sheath of all cables.
