Control Cable
01
Control Cable PVC Insulated Multi-conductor
Application
Control cable is applicable to control and monitoring loops and protection lines at a rated voltage of Uo/U no more than 450/750V, serving as a control connecting wire between electrical equipment in industrial and commercial applications.
Flame-retardant cable is designed to resist ignition and limit flame spread within a certain range during a fire, reducing the risk of fire propagation. It is ideal for environments where high flame-retardant performance is required, such as power plants, tunnels, high-rise buildings, and densely populated areas.
Fire-resistant control cable not only ensures power transmission under normal operating conditions but also maintains normal operation for a certain period after ignition. It is widely used in critical infrastructure, emergency systems, and areas where maintaining circuit integrity during a fire is essential, such as hospitals, subway stations, and emergency power control centers.
