What is the impact of unqualified insulation thickness on the cable?
2024-09-30
1. reduce the withstand voltage level of the cable: insufficient thickness of the insulation layer will reduce its withstand voltage, which may lead to breakdown under normal working voltage, causing equipment damage or personal injury.
2. accelerated cable aging: resistance to temperature changes, humidity, chemical corrosion, etc. will reduce the service life of the cable.
3. safety hazards: In the construction and maintenance process, if the insulation layer is too thin, it may cause the cable temperature to be too high. Long-term high temperature operation will accelerate the aging of the cable and even cause serious consequences such as fire.
4. increase the difficulty of laying: in the process of cable laying, if the insulation layer is too thick, it will increase the outer diameter of the cable, on the contrary, if the insulation layer is too thin, it may be easily damaged when the cable is subjected to external force.
