◆ in the fire scene, the fire-fighting cable can withstand long-term fire resistance, mechanical vibration and strong waterproof performance;
◆ in case of fire, there is no cable that emits black smoke and corrosive gas; No harm to human body;
◆ the fire-retardant fire-fighting cable is made of new oxygen isolating, flame-retardant and fire-resistant materials, and the cable has self extinguishing ability;
◆ when the fire flame of fire-resistant cable is 950-1000 ℃, the line integrity can be maintained for 180 minutes.

It is applied to the connection and power supply of fire control rooms, fire pumps, fire elevators, smoke control facilities, communication systems, fire protection systems, emergency power supplies and fire alarm system equipment in power plants, chemical plants, tunnels, stations, high-rise buildings, etc. with AC rated voltage u0/u of 300/300v;
This cable is the main link of fire protection, sprinkler head, water flow indicator, wet alarm valve, pressure switch, floor display, smoke exhaust fan valve, air supply fan, air supply valve, fire broadcast, telephone, fire suppression, sprinkler pump, controller host and display system.
Normally the cables are packed by drum,carton and put on the pallet and other customized packing are available as per international standard.
