DHG sliding contact line

1DHGbusbarProduct Introduction
（1） The power supply safety sliding contact line series products are innovatively developed and produced by our factory with reference to relevant foreign materials and products, and in response to the situation where sliding lines in domestic lifting facilities are prone to accidents. There are three types of products in this series: composite, square tube, and spliced safety sliding contact wires, which are products of our factory.
（2） The series of power supply safety sliding contact line products developed by our institute are complete and widely used. They can be used for lifting machinery such as electric hoists, beam and bridge cranes in factories, mines, warehouses, stations, ports and docks; Elevators, automated production lines, and other conductive equipment for mobile operations.
（3） Users can choose the appropriate specification of power supply safety sliding contact wire according to the model of the lifting machinery, in order to achieve technical and economic indicators such as meeting the electricity needs of the lifting machinery, saving electricity, energy, and reducing energy consumption.
（4） The correct selection of power supply safety sliding contact line is the key to achieving technical and economic benefits. According to reliability research, using this sliding contact line can improve the reliability of the system by two orders of magnitude. Users should carefully refer to this manual when selecting the power supply sliding contact line, fully understand the product performance, characteristics, etc., in order to achieve * usage effect.

IIDHG Multipole Tube Sliding Contact LineWorking principle, characteristics and uses of the product

（1） Main components and their working principles
The power supply safety sliding contact line device consists of two main components: conduit and conductor, as well as some auxiliary components, as shown in the figure:
1. Catheter: It is a semi enclosed shaped tubular component that is the main part of the safety sliding contact wire. It can be embedded with 2-9 guide rails as power supply wires as needed, and each guide rail is insulated from each other and from the outer shell to ensure the safety of power supply. And effectively prevent electric shock accidents for maintenance personnel during live maintenance. Our factory produces conduits with a length of 4m each, which can be connected to any desired length. Generally, conduits are made in straight lines, but can also be made in circular arcs according to special requirements.
2. A conductor is a set of brush housing frames that run inside a conduit. It is driven by a fork (or traction chain, etc.) placed on the electrical mechanism (such as a crane, trolley, electric hoist, etc.) to synchronize with the motor, transmitting the electrical energy through the guide rail and brush to the motor or other control components. The number of poles of the conductive electric brush is 3-16, corresponding to the number of guide rails in the conduit.
（2） Product Features
1. Safety: The power supply safety sliding contact wire housing is made of high insulation performance engineering plastic. The protection level of the shell can reach IP13.IP55 as needed, which can protect against rain, snow, frost, freezing attacks, and foreign object contact. The product has experienced various environmental conditions. Good insulation performance, no harm to maintenance personnel touching the outside of the transmission conduit.
2. Reliability: Conductive performance of transmission rails Fast heat dissipation, high allowable current density, low impedance value, and small circuit loss. Electric brushes are made of metal copper and carbon alloy materials with high conductivity and wear resistance. The conductor is flexible in movement and has good directional performance, effectively controlling contact arc and series arc phenomena.
3. Economy: The power supply safety sliding contact line device has a simple structure, high allowable current density, low resistivity, low voltage loss, and can save about 10% of electricity. It can replace steel with plastic and copper with plastic. The design is novel and does not require other insulation structures or compensation lines. It is installed on the same side of the crane control room. Save installation materials and expenses.
4. Convenience: The power supply safety sliding contact line device integrates multiple pole busbars into one conduit, making assembly simple. The fixed bracket, connecting clip, and suspension device are all supplied as universal parts. Assembly, disassembly, adjustment, and maintenance are also very convenient.
（3） Purpose: The power supply safety sliding contact line device can be used for electric hoists, electric beam and bridge cranes, stacker cranes, automatic detection lines for electromechanical products, and automated production lines; Mobile electric tools and other mobile conductive equipment, as well as fixed busbar trunking in factories, mines, workshops, and office spaces.
