Steel sliding contact line is composed of copper conductors and steel structural framework, with two structural types: combined and composite. It is supported by high-strength special insulators, installed or welded on the brackets of the track beam, thus forming a mobile power supply system for various crane machinery and equipment.
Components:
1. Sliding line: A sliding contact line is a system used for mobile power supply (literally, it is a wire for sliding contact). The sliding contact line, scientifically known as sliding conductor, full name is safe sliding contact power transmission device.
2. Insulator: Commonly known as a porcelain bottle, it is an insulator used to support the conductor. During operation, it should be able to withstand the vertical load and horizontal tension of the conductor.
3. Current collector: By contacting the sliding line, it receives electricity from the sliding line. The current collector is the carrier for the operation of the traveling crane.
Working principle: Mobile equipment needs to constantly change positions due to movement. At each different position, the mobile equipment must be able to obtain power at any time, otherwise it cannot continue moving. At this point, the sliding contact line came into being. Several conductors are laid parallel along the track of the mobile equipment, connected to the power supply. On the mobile equipment, a current collector that can draw electricity from the conductors is installed. Thus, when the equipment moves, the current collector moves synchronously with the equipment and obtains power from the conductors at any time to supply the equipment, allowing it to continue moving. The device composed of these conductors and current collectors is called a sliding contact line.
