Control cable As the connecting line between various electrical appliances, instruments, meters and automatic devices, it plays the role of transmitting various startup, operation, control, signal display, measurement and other electric energy signals Security Equal department door It is widely used in control, measurement, signal transmission, starting emergency signal, fire protection, security and interlocking systems.
Plastic insulation control Cable Technical characteristics of
Rated cable: the rated voltage is the reference voltage for cable design and electrical performance test. It is expressed in U0/U, and the unit is V U0 - effective value of voltage between any main insulated conductor and "ground" (metal shield, metal sheath or surrounding medium);
Effective value of voltage between any two phase conductors of U-multi-core cable or single core cable system.
When the cable uses the AC system, the rated voltage of the cable shall be at least equal to the nominal voltage of the system.
When DC system is used, the nominal voltage of the system shall not be greater than 1.5 times the rated voltage of the cable.
The working voltage of the system shall not be greater than 1.1 times the rated voltage of the system
