Cable protection resistance

Cable resistance refers to the maintenance measures taken to ensure that the resistance value of the cable system meets the design requirements. During the use of the cable, due to the influence of the external environment, such as humidity, high temperature, vibration, etc., it is easy to accelerate the aging of the cable insulation, resulting in the cable resistance value does not meet the design requirements. At this time, in order to maintain the normal operation of the cable system, corresponding maintenance measures need to be taken, that is, "resistance protection".

The main method of maintaining cable resistance is to test and detect the cable regularly to determine whether the resistance value of the cable is normal. If the resistance value is abnormal, you need to take measures such as replacing insulation materials and installing protective covers to ensure the reliability and security of the cable system.

Cable protection test

Cable protection testing refers to periodically testing the performance and operating status of the cable to discover and solve possible problems in time to ensure the reliability and safety of the cable system. Cable protection inspection is one of the important means to ensure the stable operation of cable system, and also the key link to ensure the quality of power supply.

Cable protection testing mainly includes the following aspects:

1. Check the appearance of the cable regularly, find damage, deformation, corrosion and other phenomena, and take timely measures to repair or replace;

2. Periodic partial discharge detection to find and eliminate possible partial discharge problems to prevent cable insulation aging;

3. Regularly test the insulation resistance of the cable, find the aging problem of the cable insulation, and take measures in time;

4. Regularly measure the temperature of the cable, find the abnormal temperature of the cable, adjust the cable load in time to prevent cable overload;

5. Check the cable vibration regularly, find the abnormal cable vibration, and take measures in time.

In summary, cable protection resistance and protection detection are important measures for cable maintenance and maintenance. By maintaining the cable, the reliability and safety of the cable system can be improved to ensure the stability and quality of the power supply.
