Steel-body sliding contact lines are composed of copper conductors and a steel structural frame, available in two types: assembled and composite. They are supported by high-strength insulators and mounted or welded onto the supports of the track beams, thereby forming a mobile power supply system that feeds various lifting machinery and equipment.

Steel body sliding contact line components:

1. Conductive Rail: A sliding contact system used for power transmission (literally, it's a wire that slides to make contact). Also known as a sliding contact device, its full name is Safety Sliding Contact Transmission Device.

2. Insulator: commonly known as porcelain bottle, it is used to support conductors and should be capable of withstanding the vertical load on the conductors and horizontal tension during operation.

3. Collector: The collector receives electricity from the contact wire, serving as the carrier for the operation of the trolley.

Operating Principle:

Mobile devices, due to their mobility, require constant position changes. At each different location, they must be able to access power sources to continue moving. This is where track power comes into play. Several conductors are laid parallel to the mobile device's track and connected to the power supply. On the moving device, a collector is installed to draw power from the conductors. As the device moves, the collector runs in sync with it, continuously obtaining power from the conductors to supply the device, allowing it to keep moving. This assembly of conductors and collectors is referred to as track power.

Application Range:

Steel body sliding contact transmission lines are a versatile sliding contact transmission device, widely used in environments with high temperatures, alternating temperatures, high voltages, strong corrosion, and high dust levels, such as: steelmaking, metallurgy, high-voltage, strong corrosion, and high dust industries, such as steelmaking, metallurgical chemicals, and port industries.
