Scope of application
Description
This product is suitable for AC 50Hz, rated voltage 6/10kV line (system maximum voltage 7.2kV) power line transmission power.
Product Characteristics
Laid in metallurgy, electric power, construction and other industries of indoor, cable trench, pipeline, directly buried and can not withstand mechanical external force fixed use occasions. Aluminum alloy power cable makes up for the shortcomings of pure aluminum cable in the past, although it does not improve the electrical conductivity of the cable, but the bending performance, creep resistance and corrosion resistance are greatly improved, which can ensure that the cable maintains stable performance when overloaded and overheated for a long time.
The standard
Executive standard
GB/T 31840-2015 Rated voltage 1kV(Um=1.2kV) to 35KV (Um= 40.5kV) aluminum alloy core extruded insulated power cable
Using features
Rated voltage
The rated power frequency AC voltage is 6/10kV, and the maximum voltage of the AC system should not exceed 7.2kV.
Operating temperature
The maximum allowable working temperature of the cable conductor for a long time is 90ºC. In the case of short circuit, the maximum temperature of the cable conductor shall not exceed 250 ° C and the duration shall not exceed 5s.
Laying temperature
When installing and laying, the temperature should not be lower than 0ºC.
Bending radius
When installing a cable, the bending radius of a single-core cable should not be less than 20 times the outer diameter of the cable, and the bending radius of a multi-core cable should not be less than 15 times the outer diameter of the cable.
