Power cable insulation material and cross section should be how to choose

author:kingsignal time:2017/07/12

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.

 

The above is a brief introduction to power cable insulation materials and interface selection, learn more about power cable content, please pay attention to kingsignal official website.
