In railway track fastening systems, gauge rods are essential for maintaining stable rail gauge. Insulated and ordinary gauge rods differ significantly in structure, materials, and applications, yet both work with elastic clips, track bolts, and anti-loosening nuts to ensure track safety.
Structurally, ordinary gauge rods are made of high-strength carbon steel or alloy steel, forming a fully rigid structure. Their ends connect to rails via iron clips, flat washers, and nuts, relying on metal strength to transmit lateral force.
Insulated gauge rods add a specialized insulating core to this design. Their middle section uses high-performance materials like nylon or epoxy glass fiber, while retaining alloy steel at the ends. Advanced processes achieve both mechanical connection and electrical isolation.
Functionally, ordinary gauge rods resist lateral rail movement and prevent gauge expansion, suited for non-electrified railways and freight lines. They work with spiral spikes and railway clips to boost stability.
Insulated rods retain this fastening function but add critical electrical isolation, blocking current flow between rails to avoid interfering with electrified railway signals. Vital for high-speed railways and urban transit, GNEE RAIL's insulated rods pass strict insulation tests, comply with UIC and AREMA standards, and integrate with rubber pads and iron base plates for complete insulating systems.
Whether insulated or ordinary, GNEE RAIL offers full-spec products and fasteners, meeting custom needs for diverse tracks and ensuring safe operations with professional quality.
