Composite railway insulator

Composite railway insulator is suitable for electric railway, also called electrical railway insulator made of polymer materials used for 25kV power lines.

Composite railway insulator

The advantages of Composite railway insulator
◆ Light weight, easy to install
◆ Hydrophobic
◆ Resistant to ozone & UV radiation
◆ Earthquake resistance
◆ Self-cleaning

Composite railway insulator composed FRP core, silicone rubber housing, weathersheds and insulator metal fittings. The end fittings which are intended to connect to a supporting structure or a conductor are made up of malleable cast iron.

The silicone rubber housing can protect the FRP core for acid and corrosion. The shed can provide creepage distance used for suitable voltage lines.

The important mechanical strength is provided by FRP core which is made of fiberglass reinforce core having require mechanical and electrical characteristics.
