Rebar Insulating Clips/Bands are used in the supporting layer and track slabs of high-speed railway and passenger dedicated lines with ballast-free tracks. Their function is to ensure the effective, reliable, and safe transmission of the track circuit over the specified transmission distance, allowing the rebar within the ballast-free track supporting layer and track slab to be insulated from each other. The use of rebar insulating clips should not affect the load-bearing capacity, durability, and structural stability of the concrete in the supporting layer and track slab, nor create any quality issues. This ensures efficient, quick, and convenient construction to meet the safety and reliability requirements of passenger dedicated line equipment. Insulating clips provide connection, fixation, insulation, and shielding between rebars, which is a crucial prerequisite for the safe conduction of the track circuit.
