From the second half of the nineteenth century, ceramics and glass were the only insulating materials suitable for high-voltage transmission lines. In the 40s of the 20th century, with the advent of polymer materials, ceramics and glass were no longer the preferred insulating materials. European and American countries began to study polymer insulators. The physical properties, electrical properties, long-term reliability, and optimal shape of the electrical insulator are then studied, and productivity continues to increase.

Among the polymer materials that can replace ceramics and glass, silicone rubber has achieved practical results since the 60s of the 20th century and stands out among several polymers. Silicone rubber insulators have more advantages than ceramic insulators. First of all, it is lightweight, easy to operate, and safe; In addition, ceramic insulators are often plagued by breakage, and a single impact can damage them. Silicone rubber insulators, on the other hand, can withstand mechanical shocks, such as a collision between a vehicle and a utility pole.

Although other polymer materials also have the above advantages, only silicone rubber will not cause much pollution to the environment. Polymer insulators are waterproof, so there is no leakage and surface arcing due to water droplets. Silicone rubber insulator is a durable material that can be used for a long time in harsh environments because its waterproof properties recover faster than other polymer insulators.
