Conducting power・enduring with quality

Quality builds our brand, safety protects every home – your trusted cable guardian

This product is suitable for power transmission and distribution in lines with an AC rated voltage of 0.6/1KV.

1、 Production execution standards

GB/T12706.1 is equivalent to the International Electrotechnical Commission IEC60502.

2、 Usage characteristics

1. The long-term allowable working temperature of cable conductors shall not exceed 70 ℃;

During a short circuit (with a maximum duration of no more than 5 seconds), the maximum temperature of the cable conductor shall not exceed 160 ℃;

3. The ambient temperature of the cable during laying should not be lower than 0 ℃.

3、 Basic model name of cable

Note: 1. Our company can provide flame-retardant and fire-resistant power cable products according to the needs of users. When ordering, add "ZR" before the prototype number to indicate flame-retardant type, and add "NH" to indicate fire-resistant type.

2. Our company can also provide VV32 and VLV32 steel wire armored power cables according to user needs. Single core metal wire armored cables should adopt magnetic isolation measures.

4、 Production scope

Note: The armor layer of single core armored cables used for communication systems should be made of non-magnetic metal materials.

Main technical parameters of cables

The maximum DC resistance of the conductor at 20 ℃ should comply with the provisions of Class 1 or Class 2 conductors in GB/T3956 standard

2. Power frequency AC withstand voltage test A C Voltage Test

Single core unshielded cables should be immersed in water for 1 hour, and a voltage of 3.5KV should be applied between the conductor and water for 5 minutes. For multi-core cables, a voltage of 3.5KV should be applied between each insulated conductor and the other conductors in sequence for 5 minutes, and the insulation should not be broken down.
