PVC insulated and sheathed control cable with apply to the Exchange rated voltage UO/u up to 450/750V and under control, monitoring and protection of the loop line, and so on, as the control wiring between the electrical equipment.
Flame retardant cables main characteristics are not easy to catch fire or ignition delay burning only applies to a certain range of flame retardant high performance requirements of the occasion.
Main characteristics of fire-resistant control cable is the cable under normal working conditions, in addition to transport electricity, cables when burning to maintain the normal operation of a certain time, suitable for the fire resistance characteristics requirements of the occasion.
(1) rated voltage UO/u up to 450/750V
(2) conductor cable long-term allowable working temperature of 70 degrees.
(3) ambient temperature is not lower than 0 ℃, recommended by permitted bending radius is as follows:
Non-armoured cable should be not less than 6 times the cable diameter times
Armored steel cable with shielding structure, shall not be less than 12 times the cable diameter times
