Control Cable
01
KVV22 CU/PVC/STA/PVC Multi-core Control Cable
Application
Control cables are used for control, monitoring, and protection circuits with a rated voltage of Uo/U up to 450/750V, acting as a vital link between electrical devices in industrial and commercial settings, ensuring efficient signal and power transmission.
Flame-retardant cables are engineered to resist ignition and restrict flame spread, minimizing fire hazards and enhancing safety. They are well-suited for applications requiring high fire protection standards, including power stations, tunnels, skyscrapers, manufacturing plants, and densely populated facilities.
Fire-resistant control cables ensure stable power transmission under normal conditions and continue functioning for a specified duration after exposure to fire, preventing system failures. These cables are essential for critical infrastructure, emergency response systems, and environments where operational continuity is crucial during a fire, such as hospitals, subway networks, data centers, and emergency power stations.
