Silicone rubber is a type of silicone polymer that can be obtained by controlling the length of the skeleton, the type of organic groups, and the crosslinking of the skeleton. And insulators are made of silicone rubber. Below, the editor will introduce the function of silicone rubber insulators.

At one end of the high-voltage power line connection tower, many disc-shaped insulators are hung to increase the creepage distance, usually made of glass or ceramics, which are called insulators.

In order to prevent floating dust and other pollutants from adhering to the surface of the insulator, forming a path that is broken down by the voltage at both ends of the insulator, which is called creepage. Therefore, increasing the surface distance, which is called creepage distance, and discharging along the insulation surface, which is called leakage distance, is called creepage distance. creepage distance=surface distance/system high voltage. Depending on the degree of pollution, in heavily polluted areas, a creepage distance of 31 millimeters/per kilovolt is generally adopted.

Zero value insulators refer to insulators whose potential distribution at both ends of the insulator is close to or equal to zero during operation.

The influence of zero or low value insulators: The insulation of line conductors depends on the insulator string. Due to manufacturing defects or external factors, the insulation performance of insulators will continuously deteriorate. When the insulation resistance decreases or becomes zero, it is called low or zero value insulators. We have tested the line and found that the proportion of zero or low value insulators is as high as about 9%. This is another main reason for the high lightning trip rate of our company's line. Insulators are smooth and can reduce the capacitive impedance between wires to reduce current loss.

Insulators are a special type of insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for power poles, but gradually developed into many disc-shaped insulators hanging on one end of the connection tower for high voltage power lines. Insulators should not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions, otherwise insulators will not play a significant role and will damage the service and operation life of the entire line.
