The H-type sliding wire products are made of single poles, which can be combined into multi-poles arbitrarily. The creepage distance between poles is large, and it can be used even in places with high humidity. The heat dissipation performance of the collector is good, and the running speed is high. The unipolar current carrying capacity of the sliding wire is large, which can meet the mobile power receiving equipment with high current. The standard length of a single sliding wire is 4m, 6m. Single-pole combined safety slide wires can be combined arbitrarily according to different needs. According to the material, it can be divided into copper and aluminum. The unipolar combined sliding wire has the characteristics of fast running speed, large carrying capacity and excellent temperature resistance, and its protection level can reach IP23. The top of the inner cavity of the aluminum sliding wire guide rail and the contact surface of the collector adopt cold pressure welding technology, and the stainless steel strip and the aluminum wire are combined into one body to avoid the electrical corrosion of the copper-aluminum contact and enhance the wear resistance of the contact. reach more than 10 years. The contact surface between the wire and the current collector is made into a "V"-shaped groove, which ensures the smooth operation of the current collector.
