0.6/1KV Xlpe insulated PVC sheathed power cable Product Name:

0.6/1KV Xlpe insulated PVC sheathed power cable


Cross-linked polyethylene insulated power cables with high mechanical strength and resistance to environmental stress well, and excellent electrical properties and chemical resistance characteristics, light weight, simple structure, easy to use. this product apply to the Exchange rated voltage UO/u up to 0.16/1KV and below, and on the transmission and distribution lines.
Flame retardant cables main characteristics is the cable easily fire or ignition delay on burning is limited to a certain range apply to cables with high intensity and high power station, subway, tunnel, high-rise buildings, large industrial and mining enterprises, oil fields, coal mines and other places.
The main characteristics of fire-resistant cable is the cable under normal working conditions, in addition to transport electricity, cable, if ignition still has some time to run smoothly, apply to nuclear power plants, subways, tunnels, high-rise buildings with respect to fire safety and the fire of life-saving place.
(1) rated voltage UO/u up to 0.6/1KV n
(2) the maximum temperature of the cable conductor is 90 ℃.
(3) the short-circuit (the longest duration of no more than 5S) cable conductor temperature does not exceed 250 ℃.
(4) cable to the ambient temperature under installation should not below 0 c and its minimum bending radius is as follows: single-core cable -20 (D+d), mm multi core cable -15 (D+d), mm (d, d respectively for cable diameter and the nominal diameter of the leading body, mm)
Cable current carrying capacity calculation
Environment temperature 25 ° c
Working of cable conductor temperature 90 ° c
When cable buried soil thermal resistivity m/w g=1.0 ℃, but not yet cable long run increased soil resistance coefficient due to moisture migration phenomenon.
Cable when buried, the axis of the cable with the ground distance of 1000mm
When multiple cables, cable distance to the axis of L=3D

PREV: Rated voltage 450/750 and polyethylene insulated cable
NEXT: 6-35KV, PVC insulated, PVC sheathed power cable
