Characteristics of Seamless Sliding Contact Lines
Mobile equipment needs to constantly change positions due to movement, and at each different position, it must be able to obtain power supply at any time, otherwise it cannot continue moving. At this point, seamless sliding contact lines came into being. Several conductors are laid parallel along the running track of the mobile equipment to connect to the power supply. On the mobile equipment, a current collector that can draw power from the conductors is installed. In this way, when the equipment moves, the current collector moves synchronously with the equipment and obtains power from the conductors at any time to provide it to the equipment, allowing it to continue moving. The device composed of these conductors and current collectors is called a sliding contact line.
1. Safety: The housing of the power supply sliding contact line is made of engineering plastic with high insulation performance. The protection level of the housing can reach IP13 or IP55 as needed, protecting against rain, snow, ice attacks, and contact by hanging objects. The product withstands various environmental conditions. It has good insulation performance and poses no harm to maintenance personnel touching the exterior of the conductive duct.
2. Reliability: The conductive rail has excellent conductivity, dissipates heat quickly, has high current density, low impedance, and low line loss. The brush is made of metal graphite material with high conductivity and high wear resistance. The current collector moves flexibly with good directional performance, effectively controlling contact arcs and series arcs.
3. Economy: The power supply sliding contact line device has a simple structure, using copper busbars with high current density, low resistivity, and low voltage loss as the main conductive body. It can save about 6% of electricity, achieving the replacement of steel with plastic and copper with plastic. The design is novel, requiring no additional insulation structure or compensation wires. It is installed on the same side as the crane control room, saving installation materials and costs. Its overall cost is roughly the same as bare steel sliding lines.
4. Convenience: The power supply sliding contact line device integrates multiple busbars into one duct, making assembly simple. Its fixed brackets, connecting clamps, and suspension devices are supplied as universal parts, making installation, disassembly, adjustment, and maintenance very convenient.
