HGRX-C-125-T Copper C-type Flexible Busbar
Darui Electric for you
Mobile equipment needs to constantly change positions due to movement, and at each different position, the mobile equipment must be able to obtain power supply at any time, otherwise it cannot continue moving. At this point, busbar came into being. Several conductors are laid parallel along the running track of the mobile equipment and connected to the power supply. On the moving 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 supply the equipment so that it can continue moving. The device composed of these conductors and current collectors is called busbar.
The power supply busbar device consists of three main components: the sheath, the conductor, and the current collector, as well as some auxiliary components.
1. Sheath: It is a semi-closed guide-shaped tubular component and is the main part of the busbar. Its interior can be embedded with 3-16 bare guide rails as power supply conductors as needed, and each guide rail is insulated from each other to ensure the safety of power supply. It also effectively prevents electric shock accidents for maintenance personnel during live maintenance. The length of each duct produced by the manufacturer varies, and they can be connected to any required length. Ordinary ducts are made in straight lines, and can also be made into arc shapes etc. according to special needs.
2. Conductor: The main material is copper, and according to its cross-sectional area, common ones are 10 square, 16 square, and 25 square.
3. Current collector: It is a set of brush shell frames running inside the duct, driven by a fork (or traction chain, etc.) installed on the power-consuming mechanism (such as traveling crane, trolley, electric hoist, etc.), so that it runs synchronously with the power-consuming mechanism and transmits the electrical energy through the guide rails and brushes to the motor or other control elements. The number of poles of the current collector brushes is 3-16, corresponding to the number of guide rail poles in the duct.
(2) Product Features
1. Safety: The shell of the power supply busbar is made of engineering plastic with high insulation performance. The shell protection level can reach IP13 and IP55 as needed, which can protect against rain, snow, and freezing attacks as well as contact with hanging objects. The product has undergone various environmental condition tests. It has good insulation performance and causes no harm to maintenance personnel who touch the outside of the power transmission duct.
2. Reliability: The power transmission guide rail has excellent conductivity, fast heat dissipation, high current density, low impedance, and small line loss. The brushes are made of metal graphite material with high conductivity and high wear resistance. The current collector moves flexibly, has good directional performance, and effectively controls contact arcs and series arcs.
3. Economy: The power supply busbar device has a simple structure, using copper bars with high current density, low resistivity, and low voltage loss as the main conductive body. It can save about 6% of electricity, realize replacing steel with plastic and replacing copper with plastic, has a novel design, requires no additional insulation structure, no compensation wire, and is installed on the same side as the crane control room, saving installation materials and costs. Its comprehensive cost is roughly the same as that of steel bare busbar.
HGRX-C-125-T Copper C-type Flexible Busbar uses high-strength special insulator supports, and is suitable for harsh environments such as high temperature, high dust, and highly corrosive gases. It also has the characteristics of a particularly large heat dissipation surface, compact and simple structure, and easy installation and maintenance.
