Causes of cable insulation breakdown

The causes of insulation breakdown can be divided into the following aspects: Voltage is too high: When the voltage of the wire and cable exceeds its rated voltage, the insulating material may not be able to withstand the high electric field strength, resulting in insulation breakdown. Insulation material defects: insulation material itself has defects, such as bubbles, cracks, foreign matter, these defects will lead to electric field concentration, easy to cause insulation breakdown. Humidity and pollution: When the wire and cable are soaked in moisture or moisture, the insulation performance of the insulation material will be affected, increasing the risk of insulation breakdown. At the same time, the filth on the surface of the wire and cable will also lead to electric field concentration, increasing the possibility of insulation breakdown. Temperature effect: Under high temperature environment, the insulation performance of insulating materials may be reduced, and insulation breakdown is prone to occur. Improper installation and use of cables: During the installation and use of cables, if the bending radius of the cables and the insulation of the joints are not properly handled, the risk of insulation breakdown will also increase. In order to avoid the occurrence of insulation breakdown, the following measures can be taken: Choose the right insulation material: Choose the right insulation material according to actual needs to ensure that it can withstand the required voltage and environmental conditions Control voltage: to ensure that the wire and cable to withstand the voltage does not exceed its rated voltage, to avoid excessive voltage lead to insulation breakdown Maintenance and protection: regularly check the insulation status of wires and cables, clean up filth in time, keep dry, and avoid insulation breakdown caused by humidity and filth Correct installation and use: Follow the installation and use requirements of wires and cables, deal with the bending radius of the cable, the insulation of the joint and other issues, and reduce the risk of insulation breakdown. In short, the causes of wire and cable insulation breakdown can be excessive voltage, insulation material defects, humidity and pollution, temperature effects, and improper cable installation and use. In order to avoid the occurrence of insulation breakdown, it is necessary to select the appropriate insulation material, control the voltage, maintain and protect the insulation state, and install and use the cable correctly.
