JDC Series High-Quality Safe Busbar
Darui Electric recommends
The JDC type safe busbar (also known as H type) uses aluminum alloy with an H-shaped cross-section as the current-carrying conductor. Through the sliding contact between the carbon brush of the current collector installed on the moving electrical equipment and the current-carrying body, electrical energy is transmitted to the equipment.
Product Features
The current-carrying conductor of the JDC busbar is made of aluminum profile, which has high strength; the good containment, insulation, and resistance to heat and cold of the plastic outer shell make it very safe. Each phase is laid separately, with good inter-phase insulation, enabling large-capacity power supply; the sliding contact surface of the profile is embedded with stainless steel wear-resistant material, greatly extending the busbar's lifespan; the standard length is 6m, and it can be installed outdoors or on the same side as the crane cab, making installation and maintenance quite convenient.
Main Components
1. Busbar: It is the main component for power transmission. The outer shell is a plastic insulating groove, embedded with an H-shaped cross-section current-carrying body (called a rail), whose contact surface with the carbon brush is a stainless steel wear-resistant body. The standard length is 6m, with a minimum bending radius (horizontal) of R>1.5m, and it can be installed upright (as shown in Figures 4.2 and 4.3) or side-mounted.
2. Hanger: A device for installing the busbar on a support frame. Before installation, the required number of hangers are pre-threaded onto the busbar, with the hanging bolts on the opposite side of the busbar slot. For 100A-400A, the installation spacing is 1.5m; for 500A-1200A, it is 3m. During installation, first tighten the hanging nuts by hand, then after adjusting the distance between the busbar and the crane track and the spacing between each line, tighten them fully.
3. Connector: Used to connect each section of the busbar supplied in fixed lengths. During installation, place a plastic protective cover on each end of the fixed-length busbar, and install an aluminum alloy connector head on one end. When installing the aluminum connector head, note that only 1/2 of the aluminum rail should be inserted into the connector, leaving the remaining 1/2 for the other rail to insert. After adjusting the connector position, tighten the connector nuts and cover with the joint protective cover.
4. Power Supply Connector: It is the component that supplies power to the busbar. It is the same device as the rail connector. When power supply is needed, drill a hole in the circular end cap of the protective cover to lead in the wire. Press the wire lug under the connector nut. According to circuit requirements, single-point or multi-point power supply can be used.
5. Expansion Joint: A special section added to compensate for thermal expansion and contraction when temperature differences are large and the busbar is long (not considered within 200m). Its installation method is the same as the connector.
6. End Cap: Used to seal both ends of the busbar, and can also serve as an end power supply. Installation method is the same as the connector.
7. Current Collector: A device that transmits the electrical energy from the busbar to the electrical equipment. It is installed on the equipment. During installation, pay attention to the direction of the mounting square steel of the current collector to avoid twisting, keep it parallel to the installation plane of each busbar, and keep the rocker arm of the current collector parallel to the busbar installation plane and perpendicular to the busbar direction. For curved busbars, use special current collectors.
The YD-G rigid current collector is composed of components such as the collector shoe, collector brush, stainless steel connecting rod, rotating arm, torsion spring, tension spring, limit plate, and support shaft. The quality of its sliding contact with the busbar mainly depends on whether the structure of the current collector is reasonable, whether the materials are excellent, and whether the torsion spring torque and tension spring force are properly designed. This device collects electrical energy. Therefore, the safe operation of the rigid current collector mainly depends on: 1. The installation of the busbar section; 2. The quality of the collector brush in the current collector; 3. Full contact with the busbar and contact pressure. In summary, it can be summed up as: three parts selection of materials, seven parts installation and adjustment.
Jiangsu Yida Electric Co., Ltd. is a manufacturer dedicated to the research and development of rigid current collectors. The company has advanced processing equipment and exquisite craftsmanship, making it one of the few star enterprises in Jiangsu. Welcome customers from all walks of life to visit our company!!!!
When selecting a current collector for a safe busbar, the first consideration is to choose a manufacturer that matches the busbar. Do not use random current collectors, as this may affect the normal operation of the crane, and in severe cases, burn out the busbar. The shoe piece on the current collector is made of copper-containing carbon-based pressed material. After purchase, check its fit with the busbar. Since the current collector itself is a consumable item, long-term use will wear the shoe piece, so it is necessary to regularly check the wear degree of the shoe piece on the current collector and replace it periodically.
