Sliding contact line is a kind of sliding transmission device suitable for abnormal high temperature and harsh environment, which is divided into low voltage type and high voltage type. It is widely used in high-temperature occasions such as coking and steelmaking. The sliding contact line operates reliably and will not have power failure. It is suitable for harsh environment with high temperature, high dust and high corrosive gas. It has high mechanical strength, is not easy to bend and deform, and can withstand strong short circuit impact current.

The sliding contact wire adopts copper conductor, which can greatly reduce the power loss. Reactance can be reduced by adding auxiliary cables. It has high mechanical strength, is not easy to bend and deform, and can withstand strong short circuit impact current. The structure is reasonable, the heat dissipation area is large, and the installation is convenient. The sliding wire of special specifications can be customized.

After adopting dovetail groove embedding technology, the screw looseness caused by vibration in the operation of other rigid sliding lines is solved, so that the sliding line is solid and reliable as a whole. The use of copper conductors can greatly reduce the electrical energy loss of conductors. After the auxiliary cable is added, the low impedance sliding contact line can be formed, and the line impedance can be doubled. The wiring can be slid on the top or side. It has the advantages of large heat dissipation surface, compact and simple structure, convenient installation and maintenance, etc.
