Power cable insulation material and cross section should be how to choose
Select the power cable, the choice of which insulation material and section is a very important prerequisite, the following for everyone to introduce
1.power cable insulation material should have the main performance
(1) high breakdown strength;
(2) low dielectric loss;
(3) a very high insulation resistance;
(4) excellent resistance to discharge performance;
(5) has a certain degree of flexibility and mechanical strength;
(6) long-term stability of insulation properties.
2.The choice of power cable should follow the following principles:
(1) the rated voltage of the cable is greater than or equal to the rated voltage of the power supply system at the installation point;
(2) the cable continually allows the current to be equal to or greater than the maximum continuous current of the supply load;
(3) core cross-section to meet the stability of the power supply system when the short-circuit requirements;
(4) according to the length of the cable to determine whether the voltage drop to meet the requirements;
(5) The minimum short-circuit current at the end of the line should be such that the protective device is reliable.
