Upper Contact Insulation Support for Power Rail - China Suppliers & Factory for DC750V/1500V Applications
Product Overview
Designed for DC750V conductor rail power systems on conventional railways, this overhead contact insulation support and protection system ensures safe and reliable operation where shoegear collects current from the upper contact rail. The complete assembly includes the insulated support bracket, clamp plates, protective cover brackets, and the protective cover itself. Manufactured from glass fiber reinforced unsaturated polyester molding compound, the system combines high mechanical strength with excellent electrical insulation. The support bracket is formed by compression molding, while the protective cover is produced by pultrusion.
