HFP-4-10/50A Multi-pole Busbar Trolley Wire
Darui Electric recommends
The power supply safety trolley wire device consists of a conduit, a current collector, and some auxiliary components:
1. Conduit: It is a semi-enclosed special-shaped tubular component, which is the main part of the safety trolley wire. Inside, 2-9 bare guide rails can be embedded as power supply conductors as needed. The guide rails are insulated from each other and from the shell, ensuring power supply safety. During live maintenance, it effectively prevents electric shock accidents for maintenance personnel. Each conduit produced by our factory is 4m in length and can be connected to any required length. Generally, conduits are made straight, but can also be made into arc shapes or other special shapes as required.
2. Current collector: It is a set of brush frames running inside the conduit, driven by a fork (or traction chain, etc.) installed on the electrical mechanism (such as cranes, trolleys, electric hoists), making it run synchronously with the electrical mechanism. It transmits electrical energy from the guide rails and brushes to the motor or other control elements. The number of poles of the current collector brushes ranges from 3 to 16, corresponding to the number of guide rails in the conduit.
(2) Product Features: DHGJ-4-70 Aluminum Alloy Shell Multi-pole Trolley Wire
1. Safety: The shell of the power supply safety trolley wire is made of engineering plastic with high insulation performance. The shell protection level can reach IP13 or IP55 as needed, protecting against rain, snow, frost, ice, and foreign object contact. The product has been tested under various environmental conditions. It has good insulation performance and poses no harm to maintenance personnel touching the outside of the conduit.
2. Reliability: The power transmission guide rails have excellent conductivity, fast heat dissipation, high allowable current density, low impedance, and low line loss. The brushes are made of metal copper and carbon alloy materials with high conductivity and high wear resistance. The current collector moves flexibly with good directional performance, effectively controlling contact arcs and arc chaining.
3. Economy: The power supply safety trolley wire device has a simple structure, high allowable current density, low resistivity, low voltage loss, saving about 10% electricity. It uses plastic instead of steel and copper, with novel design, no additional insulation structure, no compensation wire needed, and is installed on the same side as the crane control room, saving installation materials and costs.
4. Convenience: The power supply safety trolley wire device integrates multiple pole busbars into one conduit, making assembly simple. Its fixing brackets, connecting clamps, and suspension devices are supplied as universal parts. Installation, disassembly, adjustment, and maintenance are also very convenient.
(3) Applications: The power supply safety trolley wire device can be used for electric hoists, electric beam cranes, and overhead cranes; stackers, automatic testing lines for electromechanical products, automated production lines; mobile electric tools and other mobile conductive equipment, as well as fixed busbar trunking in factories, mines, workshops, and office areas.
3. Product Structure Types, Applicable Occasions, and Models: DHGJ-4-70 Aluminum Alloy Shell Multi-pole Trolley Wire
(1) Structure Types: The power supply safety trolley wire conduit is composed of an aluminum alloy shell (metal type), a plastic pipe wrapped with an aluminum alloy shell (composite type), a plastic conduit, a current collector, intermediate connectors (power supply units), end caps (end power supply units), and other accessories. The conduit shape can be square or split.
1. Reinforced engineering plastic conduit: Its cross-section is square, suitable for outdoor use with ambient temperatures from -30°C to +55°C. The guide rail cross-sectional areas include: 10, 16, 25, 35, 50, 70, 95, 140 mm², etc. The number of guide rail poles includes: 3, 4, 5, 7, 8, 16 poles, etc.
2. Metal composite conduit: It is a reinforced conduit with an additional layer of aluminum alloy composite shell to improve temperature resistance and anti-aging performance, suitable for outdoor environments with temperatures from -30°C to +65°C and high-temperature workshops.
3. Metal type: The metal conduit uses an aluminum alloy shell and is made with insulating protective materials, suitable for environments with temperatures from -40°C to +80°C. 3-4.
