ENGLISH:Fire-resistant power cable with rated voltage 0.6/1kV
CLASS:Fire-resistant power cable
JANE SAID:The characteristics of fire-resistant cables are that they can maintain normal operation for a certain period of time under the condition of flame burning, and can maintain the integrity of the line. Fire-resistant cables produce less acid gas and smoke when they burn, and their fire-resistant and flame-retardant properties are greatly improved, especially when they are burned, accompanied by water spray and mechanical blows, the cable can still maintain the integrity of the line.

use |
Ø It is suitable for the fixed laying of electric power supply, transmission and distribution lines with a rated voltage of 0.6/1KV that require cables to continue to operate for a certain period of time under fire. Such as: high-rise buildings, oil fields, power stations, power plants, mines, chemicals, mines, subways and other occasions that require high fire protection conditions. They are also required cables for emergency power supplies, fire pumps, and elevator communication signal systems. This product has high fire resistance. , In the case of direct flame burning, no short circuit or open circuit fault will occur within a certain period of time (not less than 3h), to ensure that the power supply is continued to maintain lighting and transmission signals, and to protect personnel with enough time to safely evacuate, and is conducive to extinguishing and reducing Small loss.。 |
