Fireproof Cable characteristic
The main characteristic of flame-retardant cable is that it is not
easy to catch fire or the burning after fire is limited to a
certain range, which can avoid the major disaster caused by fire
delay. That is, the flame retardant cable is burned, after the test
fire source is removed, the spread of flame is only within a
limited range, residual flame or residual burning within a limited
time to extinguish the cable.
Its basic characteristics are: in the case of fire may be burned
out and can not operate, but can prevent the spread of fire.
Generally speaking, the cable in case of fire, can limit the
combustion in the local scope, do not produce spread, keep all
kinds of other equipment, avoid causing greater losses.
Copper/aluminum core XLPE high voltage power cable, commonly used
in transmission an distribution lines, its rated voltage up to
35KV.
All kinds of high voltage power cables produced by ZHUFENG Company
have excellent heat resistance and good insulation characteristics.
Using XLPE material, hardness, stiffness, wear resistance and
impact resistance have been improved, and they have strong acid and
alkali resistance and oil resistance.
Flame retardant high-voltage cables are widely used in fixed
granary circuits with rated AC voltage up to and including 35KV.
The maximum long-term operating temperature of the conductor is 90
degrees Celsius, and the maximum short-circuit temperature is not
more than 250 degrees Celsius (5s). Such as power, construction,
industrial and mining, metallurgy, petroleum, chemical,
transportation and other departments, high-rise buildings,
underground railways, underground streets, large power stations and
important industrial and mining enterprises and fire safety and
lifesaving related places,for example, fire fighting equipment and
emergency guide lights and other emergency facilities power supply
lines and control lines.
