High Voltage Prop Insulator Wholesale

    A lot of disc-shaped insulators are hung at one end of the High-voltage wire connection tower. It is to increase the creepage distance. It is usually made of glass or ceramic or rubber, which is called an insulator. In order to prevent dust and other contaminants from adhering to the surface of the insulator, the formation of a path is broken down by the flashover at both ends of the insulator, that is, creepage. Therefore, increase the surface distance, that is, the creeping distance. The distance of discharge along the insulating surface, that is, the leakage distance, is called the creeping distance. The creeping distance = Surface distance/system maximum voltage. According to the degree of pollution, the creepage distance is generally 31 mm/kV in heavily polluted areas. A zero-value insulator refers to an insulator whose potential distribution across the insulator is close to zero or equal to zero during operation. Influence of zero-value or low-value insulators: The insulation of line wires depends on insulators, due to manufacturing defects or external effects, such as: the surface of the insulator is too dirty, lightning strikes, etc. The insulation performance of insulators will continue to deteriorate, when the insulation resistance is reduced or zero, it is called low-value or zero-value insulators. Insulators are smooth to reduce capacitive reactance between wires to reduce current loss.
