66KV composite suspension disc insulator

    The conductors of overhead power lines are connected and fixed on the tower by insulators and hardware. Insulators used for the insulation of wires and towers must not only withstand the action of working voltage, but also be subjected to the action of overvoltage during operation, and also bear the action of mechanical force, temperature changes and the influence of the surrounding environment, so the insulator must be in good condition. insulation properties and certain mechanical strength. Usually, the surface of the insulator is corrugated. This is because: First, the leakage distance (also known as creepage distance) of the insulator can be increased, and at the same time, each wave strand can block the arc; second, when it rains, the sewage flowing from the insulator will not directly It flows from the upper part of the insulator to the lower part to avoid the formation of sewage column and cause short circuit accident, which plays the role of blocking the flow of sewage; third, when the pollutants in the air fall on the insulator, due to the unevenness of the insulator, the pollutants will not be able to It is evenly attached to the insulator, which improves the anti-fouling ability of the insulator to a certain extent. There are many types of insulators for overhead power lines, which can be classified according to the structure type, insulating medium, connection method and bearing capacity of the insulator.
