What is Continuity Bonds / Rail Signal Bonds and TLJB Bonds?

Exothermic Weld for Continuity Bonds Rail Signal Bonds and TLJB Bonds - Amiable - AURAWELD®

Continuity Bonds Rail Signal Bonds and TLJB Bonds are essential components for maintaining reliable electrical connections in rail systems. These bonds ensure the seamless transmission of signals and continuity across rail joints, enhancing the safety and efficiency of railway operations. With high-quality materials and precise engineering, Amiable Impex provides Continuity Bonds Rail Signal Bonds and TLJB Bonds that offer dependable performance in demanding environments.

1. Continuity Bond

this is a wire connected to 2 consecutive tracks to maintain electrical continuity. The welding is done on the rail head (top of the rail track, below 1/2 round on which the wheels roll). A set of two moulds are used to achieve the joints (LH – Left Hand & RH – Right Hand). The wire size and length are fixed as mentioned in the enquiry. The wire is Copper and its capped at both ends (by a hammer head die). Normal Cable Size – 10sqmm – 4.05 mm dia.

2. TLJB

this is a connection from rail web (centre of rail track)/ earth pipe to TLJB (equipment) terminal. Here again LH & RH moulds are used. The wire sizes can be different. It is also known asTrack Lead Joint Bond / Track Lead Junction Box. Normal Cable Size is- 35sqmm – 8mm Dia

Both tasks are simple to perform provided you can source the continuity bond wires

(1). Weld metal required will be 25g for 3/16 dia cable size.
JOINT BOND KITS

A kit comes with the following items:

  • 200 Shots
  • 2 replacement Molds (Right & Left)
  • Flint ignitior

HAMMER DIES : Bonds can be made in the field using supplied copper alloy signal cable, or your own cable, a copper sleeve, and a hammer die.
