Function of pillar epoxy resin insulator

There are many disc-shaped insulators hanging at one end of the high-voltage wire connection tower. It is used to increase the creepage distance. It is usually made of glass, ceramic or rubber, and is called high voltage standoff insulators. In order to prevent dust and other dirt from adhering to the surface of high voltage epoxy, forming a path to be flashed and broken down at both ends of epoxy resin insulator, that is, creepage. Therefore, the surface distance is increased, that is, the creepage distance. The distance of discharge along the insulation surface is called the leakage distance. Creepage distance = surface distance/system maximum voltage. According to the degree of dirt, the creepage distance is generally 31 mm/kilovolt in heavy pollution areas. Zero value high voltage epoxy resin refers to an insulator whose potential distribution at both ends of high voltage standoff is close to zero or equal to zero during operation. The influence of zero value or low value insulators: The insulation of the line conductor depends on the insulator. Due to manufacturing defects or external effects, such as: the surface of the insulator is too dirty, lightning strikes, etc. The insulation performance of the insulator will continue to deteriorate. When the insulation resistance is reduced or zero, it is called a low value or zero value insulator. The insulators are smooth to reduce the capacitive reactance between wires to reduce current loss.
