Plastic insulated control cables
Application of standard
The product is manufactured according to the standards of GB/T9330-2008 , IEC60227 < Polyvinyl chloride insulated cables of rated voltages up to and including 450/750V> and IEC60502 m=1.2kV) up to 30kV(Um=36kV)>. PVC insulated and sheathed control cable is suitable for the interconnection in controlling, signaling, protecting and measuring systems with rated voltages up to 0.6/1kV.
 
Operating characteristic
Rated power- frequency voltage U0/U:450/750V or 0.6/1kV.
Max. permissible continuous operating temperature of conductor: 70ºC.
The ambient temperature for cable installation: ≥0ºC. If the ambient temperature is lower than 0ºC, the cable should be preheated.
The bending radius of cables are recommended as follows:
Non-armoured cable: not less than 6 times of the cable diameter.

Low Voltage Current Transformer

Major Performance

●Power frequency withstand voltage

The power frequency withstand voltage of the primary winding to the secondary winding and the grounding shell and the secondary winding to the ground shell is 3kV, and the experimental time is 5min. There is no damage to the insulation and no discharge phenomenon on the surface

●interturn dielectric strength

The secondary winding is open, and the primary winding is open to expand the rated current and maintain for 1min. The insulation between turns of the secondary winding of the transformer is not damaged
