Upper Contact Insulation Support for Power Rail

Upper Contact Insulation Support for Power Rail system provides insulation support and protection for DC750V/1500 third-rail power supply on conventional railways. The shoegear collects current from the upper contact rail. The assembly includes insulated brackets, clamp plates, and protective covers. Materials are glass fiber reinforced unsaturated polyester, formed by compression or pultrusion. Key ratings include static compression load ≥500 kg for the bracket, dry flashover voltage ≥60 kV, and wet flashover ≥30 kV. The cover withstands a 100 kg drop from 450 mm without cracking. Reliable performance under mechanical and electrical stress.

    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.
    Upper Contact Insulation Support for Power Rail is to provide robust insulation support and electrical protection for the steel-aluminum composite conductor rail. The design accommodates top-contact current collection, making it suitable for standard railway applications. All components are engineered to withstand mechanical loads, environmental exposure, and electrical stress over a long service life.
    Upper Contact Insulation Support for Power Rail11
    Upper Contact Insulation Support for Power Rail complies with relevant enterprise standards and customer technical requirements. It is specifically designed for DC750V conductor rail power supply systems on conventional railways.

    Production Capacity & Quality Assurance

    OurUpper Contact Insulation Support for Power Rail are manufactured on a fully automated production line. The facility is capable of producing around 100,000 sets per year.

    We have tight control over incoming raw materials. Every batch is tested in our lab before it enters the factory. We only release a batch for production once we've confirmed that its properties meet our requirements.
    Product sampling inspections are carried out at three stages: before production begins, during the manufacturing process, and after completion.

    All tests are performed in our own laboratory. The lab holds CNAS accreditation, so our test results are accepted under international standards.

    Lead time: 7 to 30 days, excluding design and mold development.
