Upper Contact Insulation Support for Power Rail - High-Quality China Supplier and Factory for DC750V/1500 Systems

,

Upper Contact Insulation Support for Power Rail system is essential for providing robust insulation support and protection for DC750V/1500 third-rail power supply systems on conventional railways. Our innovative shoegear efficiently collects current from the upper contact rail, ensuring reliable power delivery. The assembly features high-quality insulated brackets, durable clamp plates, and protective covers, crafted from glass fiber reinforced unsaturated polyester through advanced methods like compression or pultrusion. Key specifications include a static compression load rating of ≥500 kg for the brackets, with dry flashover voltage ≥60 kV and wet flashover voltage ≥30 kV. Additionally, our protective cover can withstand a drop test of 100 kg from 450 mm without showing any signs of cracking. Experience reliable performance under both mechanical and electrical stress with our products, sourced from trusted China suppliers and manufactured in our state-of-the-art factory.

    Custmized Railway Ballast Vibration Reduction Mat EN Standard101

    Application

    Widely used across China’s rail network, the Elastic Ballast Mat delivers proven results. Installed under the ballast bed, it boosts track elasticity, cuts down ballast breakage, and improves load distribution—especially on curves and turnouts. Designed with a puncture-resistant top layer and an elastic damping layer, Ballast Mat performs reliably with or without retaining walls.

    Quality Assurance

    We have designed, manufactured, and exported ballast mats for over 20 years. Our products are installed on more than 40 metro lines across major Chinese cities like Beijing, Shenzhen, Wuxi. Customer satisfaction stands at 98%.
    number
    Before leaving our factory, the ballast mats will be tested strictly according to standard requirements . For customers who require more, we carry out type tests at our in-house testing centre. 

    Tests include:
    • Fatigue testing
    • Static and dynamic stiffness measurement
    • Tensile testing

    This process verifies Elastic Ballast Mat reliability under real working conditions.

    Production Capacity

    We handle Ballast Mat production in-house at our dedicated continuous foaming workshop. The facility runs on an automated German production line, giving us consistent quality and high output. Current annual capacity stands at 900,000 square metres of Railway ballast vibration reduction mat.

    Custom Mould Design & Manufacturing

    – In-House, Start to Finish
    Our Mould Engineering Department operates a full digital workshop equipped with more than 20 CNC machines, including machining centres, spark eroders, and wire cutters. This allows us to design and manufacture a wide range of moulds for the rail transit industry – injection moulding, rubber, SMC, and specialised types such as auto-core-pulling bush moulds.

    Annual output stands at 300 sets of moulds and tooling.

    If your project calls for a non-standard shape for Elastic Ballast Mat, a special material, or a unique production feature, we have the equipment and the experience to deliver.
