Seamless current collector for sliding contact wire is a high-performance conductive device mainly used to provide continuous and reliable power supply for small and medium-sized mobile equipment. Its core feature is "seamless", that is, in the entire sliding contact wire system, the current transmission path is continuous, and there are no other interfaces except the power supply points. This design effectively avoids problems such as poor contact and power outages caused by too many interfaces.
Working principle
The seamless current collector for sliding contact wire directly transmits electric power to the electrical equipment through the sliding contact between the collector brush and the guide rail, so as to realize the mobile power supply of the system. The current collector is a set of brush brackets running in the conduit, which is driven by a shift fork (or traction chain, etc.) installed on the power consumption mechanism (such as crane, trolley, electric hoist, etc.) to run synchronously with the power consumption mechanism, and transmit the electric power through the guide rail and the brush to the motor or other control components.
Materials and performance
The conductor of the seamless sliding contact wire is usually made of oxygen-free copper, which has excellent electrical conductivity. Moreover, copper is tightly combined with plastic, and will not cause poor contact due to vibration. Its shell material is generally PVC, which has good insulation, impact resistance and ultraviolet resistance. In addition, the seamless sliding contact wire is made of special materials, which runs smoothly, has high speed, low noise, and is easy and time-saving to install with small space occupation.
