Composite Long Rod Insulator

Because the fiberglass rod has much higher mechanical strength than porcelain and the density of the rubber material is much lower than porcelain, the weight of the high voltage composite insulator is much lighter than that of porcelain insulators. This weight difference increases with the increase of voltage level. Therefore, silicone rubber insulators tend not to require cranes or other lifting equipment for loading and unloading. The lighter weight also allows the use of lightweight and less expensive structures and installation equipment. The smaller size and weight also make its shipping cost lower than that of equivalent porcelain insulators. Electric composite insulators are conducive to use in dense urban areas and can provide very narrow road land. And this power composite insulator provides a high strength-to-weight ratio, which allows for larger spans, lower structural costs and improved appearance. The very light weight of silicone rubber composite insulators can also increase the distance between the conductor and the ground and the distance between the phases to reduce electric and magnetic fields. Silicone rubber composite strain insulators can also promote the development of compact transmission lines that reduce the effects of electromagnetic fields.

Silicone rubber composite insulators are conducive to use in dense urban areas and can provide very narrow road land. And it provides a high strength-to-weight ratio, which allows for larger spans, lower structural costs and improved appearance. The very light weight of polymeric composite insulators can also increase the distance between the conductor and the ground and the distance between the phases to reduce electric and magnetic fields. Silicone rubber composite insulators can also promote the development of compact transmission lines that reduce the effects of electromagnetic fields.

Non-porcelain insulator is an emergency product, which can build a temporary line in a very short time and reduce the cost.

Water forms water droplets on the surface of silica gel, and the very fine film of silica gel liquid basically swallows up the dirt, thereby inhibiting the dissolution of ions in water, increasing the surface resistance, reducing the leakage current, and increasing the pollution flashover voltage. This performance is maintained even when the silica gel ages. Studies have shown that the wet withstand voltage and pollution withstand voltage of composite insulators are 2 to 2.5 times that of porcelain insulators with the same creepage distance. And there is no need to clean, and it can operate safely in heavily polluted areas.
