High voltage composite suspension insulator

    For common insulator faults, maintenance should be carried out in a timely, effective and targeted manner.

    The short dry arc distance, the single-ended configuration of the equalizing ring, and the connection resistance exceeding the standard are the main reasons for the lightning flashover of the insulator. In maintenance and protection, lengthened synthetic insulators should be used, and double equalizing rings should be installed to reduce the grounding resistance of the tower.

    In order to effectively prevent bird damage, the operating unit should install bird nets, bird needles and bird covers on lines where bird damage often occurs.


    For the line using the pressure equalizing ring, the size of the umbrella skirt should be equal, and the distance between the umbrellas should meet the technical requirements. If it does not meet the requirements, it is necessary to add insulator climbing columns to reduce ice flashover accidents. At the same time, patrol inspections should be strengthened to regularly Monitor insulators, different regions, different environments for tension, electrical properties and insulation aging tests.

    In order to prevent contamination flashover, insulators should be cleaned regularly, and the frequency of cleaning should be increased in contaminated areas.

    In order to increase the creepage distance and improve the insulation level of the insulator, the insulator manufacturer reminds you that you can also use a dust-proof insulator with better anti-fouling effect, or coat the surface of the insulator with dust-proof paint to improve the anti-fouling ability of the insulator.
