Copper-plated connecting track

The track circuit is an important device for outdoor signal interlocking. One of its important functions is to ensure safe operation and diversion operations, supervise and check whether there are trains running, diversion operations or cars occupying a fixed part of the road (including station lines), and display whether the track is complete; another track circuit An important function is to detect the breakage of the rail. However, in order for the track circuit to work properly, it is necessary to use track connecting wires. Solder the copper-coated welding wire between the track joint side joints of the railway, connect the power supply at one end and the electrical appliance at the other end, and then use the track as a conductor to conduct the current of the track circuit. Therefore, copper-plated bonding wire is a very important device.
