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.
