Features
Railroad insulated joint is a specialized rail component designed to provide electrical isolation between two rail sections while maintaining mechanical continuity. Key functions include:
Electrical Insulation: Blocks current flow in track circuits, enabling precise signal system operation (e.g., ATP, CTC).
Mechanical Load Transfer: Withstands dynamic wheel loads and maintains rail alignment.
Corrosion Prevention: Isolates electrolytic corrosion between dissimilar metals.

High-Speed Rail: Requires vibration-resistant designs
.
Urban Transit: Waterproof variants (e.g., rubber-sealed joints in subway tunnels).
Maintenance: Insulation degrades due to contamination; regular resistance testing is critical.
Mechanical Insulated Joints
Use physical barriers for insulation; common in conventional railways.
Glued Insulated Joints
Epoxy-bonded for higher durability; used in high-speed rail.
Heat-Shrinkable Joints
Feature waterproof outer sleeves for harsh environments.

Insulation Resistance: ≥10 MΩ (tested at 500V DC).
2
Shear Strength: ≥1,500 kN longitudinal load capacity (for heavy-haul routes).
3
Temperature Range: -40°C to +70°C
4
Fatigue Life: ≥2 million load cycles (simulating wheel passes).
