ZRC-KVV/SB PVC Insulated Control Cable

Specifications

1. Colours distinguish

Colours distinguish for insulated core of 5 cores and below

2. Digits distinguish

For the cable distinguished by digits, the colours of insulation and digits marks should be different distinctly so that it is easy to separate the cores in installing. The colour of insulation should be black, white, yellow, corresponding digits colour is white, black blue etc

3. Application

Rated voltage U0/U should be 450/750v-600/1000v

U0-Valid value of he voltage betwwen main insulated conductor and earthing

U-Valid value of voltage between any two phases conductor in multicore cable or single cable system.

When AC. System is applied, the rated voltage of cable should be at least equal to the nominal voltage of the system. When DC. System is applied, the nominal voltage of this system should not be more than the rated voltage of the system by 1.5 times

4. The permitting long-term perating temperature of cable conductor should be: PVC insulation:70°c
