Products Description
Our 36kV composite insulators is designed to be durable in networks that transmit high voltage power. For mechanical strength, it has an epoxy fiberglass core rod that is resistant to corrosion. It is protected from UV damage, pollution, and harsh weather conditions by its high-quality silicone rubber housing. For good mechanical load-bearing and electric performance, the metal end fittings are perfectly crimped to the core.
This insulator, which is produced for overhead transmission lines, is the most suitable choice for enterprises and electricity companies who required high efficiency with low maintenance because of its excellent electrical characteristics, lightweight design, and long-term durability.
