Introduction of Power cable
Power cable is a cable used to transmit and distribute electrical energy.Commonly used in urban underground power grid, the outgoing line of power station, internal power supply of industrial and mining enterprises and underwater transmission lines. In the electric power line,the proportion of the cable is gradually increased.
Power cable is in the power system’s main lines for transmission and distribution high-power electrical energy cable products,including 1-500KV and above a variety of voltage levels, all kinds of insulated power cables.
Power cable standards
This product according to GB / T12706-2008 "rated voltage of 35kV and below copper core, aluminum core plastic insulated power cable" standard production,at the same time, according to user needs according to the International Electrotechnical Commission recommended standards IEC, British standards, German standards and the United States standard production.
Scope of application
This product is suitable for power frequency rated voltage 0.6 / 1kV and below the distribution network or fixed installation of industrial installations.
Characteristics of Power cable
1.Power frequency rated voltage: Uo / U (Um) 0.6 / 1 (1.2) kV.
2.Cable conductor allows long-term work Maximum temperature: 90 ℃.
3.When a short circuit (the longest duration of not more than 5s) Cable conductor to allow maximum temperature does not exceed 250 ℃.
4.Ambient temperature of cable laying should not be lower than 0 ℃.
5.The bending radius of cable should not less than 20 times the cable diameter.
