Overview
The multi pole tube sliding contact power bus transmission guide rail has high conductivity, fast heat dissipation, high allowable current density, low impedance value, and small line 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.

Multi pole tube sliding contact power busbar
main advantages
1. The power busbar has high safety performance; Long service life, as well as advantages such as simple installation and easy maintenance.
2. Compared to cables, power busbars are more economical and practical for use in workshops. Once the power busbar is fixed in place, it no longer moves. Additionally, there are specialized wiring accessories, which are more economical and practical compared to cables.
3. It can make maximum use of the limited space in the workshop to layout the power bus. Moreover, the power bus has high flexibility and can be extended to any mobile equipment in the workshop.
1. Sliding contact wire conduit: 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. The length of each produced conduit is 6m, and it 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. The sliding contact wire conductor is a set of brush housing frames that run inside the conduit. The sliding contact wire 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 of the sliding contact wire brush through the guide rail 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.

Mobile devices need to constantly change positions due to their mobility, and at each different location, they must be able to obtain power at any time, otherwise they cannot continue to move. At this point, the sliding contact line emerged. Several conductors are laid in parallel along the operating track of the mobile device and connected to the power supply. Install a current collector on the mobile device that can draw electricity from the conductor. In this way, when the device moves, the collector runs synchronously with the device and obtains power from the conductor at any time to provide power to the device, so that the device can continue to move. The device composed of these conductors and current collectors is called a sliding contact wire.
1. Sliding contact wire 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 sliding contact line has experienced various environmental conditions. Good insulation performance, no harm to maintenance personnel touching the outside of the transmission conduit.
2. Reliable sliding contact line: The transmission guide rail has good conductivity, fast heat dissipation, high allowable current density, low impedance value, and small line 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. Sliding contact line 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 realizes the use of plastic instead of steel and copper, with a novel design that does not require other insulation structures or compensation lines. It is installed on the same side of the crane control room. Sliding contact lines save installation materials and costs.
4. Convenient sliding contact line: 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 of the sliding contact line are all supplied as universal parts. Assembly, disassembly, adjustment, and maintenance are also very convenient.
Order of installation tasks
1. Install the angle steel bracket along the track at the preset position, and the spacing between the brackets should follow the standard spacing as much as possible, ensuring a parallel position with the centerline of the track.
2. Install the hanging clip on the angle steel bracket, insert the nut into the appropriate position, and ensure that the hanging clip can still move left and right on the long hole of the bracket.
3. Install the sliding wire guide rod from one end of the track, with a distance of 750mm from the end to the first bracket as much as possible.
4. Assemble terminal sheath, joint and joint sheath, power input and sheath.
5. Install expansion components and set the gap between components reasonably according to the on-site ambient temperature.
6. Install the fixing clip.
7. Select a reasonable location on the mobile device to install the collector bracket, ensuring that the collector is at a standard height.
8. Install the current collector.
9. Connect the incoming cable and collector cable.
10. After confirming the correct installation, power on and test drive to check if the phase sequence of the power supply needs to be changed.
11. Run the equipment slowly and repeatedly to both ends of the track, paying attention to whether there is any collision, ignition, or deviation of the current collector. If there is any abnormality, stop the vehicle immediately and cut off the power to identify the cause of improper installation and make adjustments.
12. After confirming that the equipment has been running repeatedly and there are no abnormal phenomena, power off again and tighten all the fixing bolts of the lifting clamps.
13. Power on the test drive and confirm that the installation is correct.
Quality can be measured according to the following standards:
1. Carbon brush service life - belongs to consumables, and the driving distance affects the equipment maintenance cycle.
2. Quality of sliding contact wire shell - applicable temperature, environment, etc.
3. The performance of the current collector mainly depends on the service life of the wheels, the design of the turning wheels, and whether the current collector can be used in various environments.
4. Expansion problem of sliding contact line - when the length exceeds 100 meters, expansion problem should be considered.
5. Voltage drop issue - voltage drop varies depending on the length of various copper bars.
Can be used for electric hoists, electric beam and electric single beam bridge cranes; Stacker cranes, automatic inspection lines for electromechanical products, automated production lines, mobile electric tools and other mobile power receiving equipment, as well as fixed busbar trunking in factories, mines, workshops, and office spaces.
The commonly used single pole H safety sliding contact wire is a semi enclosed tubular component that serves as the main body of the sliding contact wire for protection purposes. 3-16 bare body guide rails can be embedded internally as power supply wires as needed, and each guide rail is insulated from each other to ensure the safety of power supply. There have been significant improvements in terms of grade and insulation, making it safe and reliable.
It is mainly divided into commonly used sliding contact wires such as single pole aluminum sliding contact wire, single pole copper sliding contact wire, steel sliding contact wire, multi pole tube sliding contact wire, seamless sliding contact wire, copper contact wire, etc. Single pole sliding contact line, multi pole tube sliding contact line, seamless sliding contact line belong to safety sliding contact line, and steel sliding contact line belong to non safety sliding contact line.
