Ground Line Porcelain Insulator Description:

Ground line porcelain insulator is made of electrical ceramic material, used to connect the earth wire and support components of a kind of insulator device. Its main function is to keep the earth wire insulated from the surrounding environment to prevent electrical equipment failure and personal safety accidents caused by abnormal grounding.

Ground Line Porcelain Insulator Features:

High strength: ceramic material has high compressive strength and bending strength, able to withstand large mechanical loads.

Good insulating property: ceramic material has good insulating property, which can effectively cut off the flow of ground current between the grounding device and the surrounding environment and prevent the ground current from leaking.

Good corrosion resistance: ground porcelain insulators can withstand acid, alkali, salt and other chemical substances, suitable for a variety of harsh environments.

Good anti-fouling performance: In order to further improve the insulator’s anti-fouling performance, the surface of the ground porcelain insulator is usually coated with a layer of special insulating coatings to reduce the leakage and running phenomenon.
