Anping County Boli Hardware Wiremesh Products Factory (established in 1998) is a professional manufacturer specializing in railway fastening components. With an annual export value of US$5 million – US$10 million, we serve global markets including North America, South America, Europe, Asia, Africa, and Oceania. Our Insulated Rail-to-Sleeper Fastening System features high-quality Nylon 66 components, offering 1000V dielectric strength and reliable elastic fastening performance. This product is designed to ensure safe, durable, and maintenance-free rail fixation for electrified railway tracks and heavy-load applications.
Key Features & Technical Specifications
- 1000V Dielectric Strength – Provides excellent electrical insulation between rail and sleeper, preventing current leakage and ensuring worker safety in electrified railways.
- Nylon 66 Material – High mechanical strength, excellent wear resistance, and good fatigue resistance. Suitable for harsh environments with temperature ranges from -40°C to +120°C.
- Elastic Fastening Design – Maintains consistent clamping force, absorbs vibrations, and reduces rail movement, extending track life and reducing maintenance costs.
- Corrosion & UV Resistant – Nylon 66 is inherently resistant to many chemicals, moisture, and UV radiation, making it ideal for outdoor railway applications.
- Easy Installation – Pre-assembled components reduce on-site labor time. Compatible with standard rail profiles and sleeper systems.

Advantages for Your Business
- Enhanced Safety – The 1000V dielectric strength significantly reduces the risk of electrical accidents, meeting stringent safety requirements for electrified lines.
- Reduced Maintenance – Elastic fastening absorbs dynamic loads, minimizing rail creep and fastener loosening. This lowers inspection and replacement frequency.
- Cost-Effective – Nylon 66 components are lightweight yet durable, reducing shipping costs and extending service life compared to traditional metal fasteners.
- Global Compatibility – Designed to fit standard rail profiles (e.g., UIC60, 54E1, etc.) and various sleeper types (concrete, wood, steel).
- Customizable Options – Available in different colors, sizes, and clamping forces. We can also tailor the system to your specific rail gauge or environmental conditions.
Our fastening system is widely used in metro systems, high-speed railways, cargo lines, and industrial sidings. The combination of Nylon 66 insulation and elastic design ensures both electrical isolation and mechanical stability, even under heavy traffic and extreme weather.
