How long is the straight section of DMHP-4-35/140 multipole tube sliding contact line

How long is the straight section of DMHP-4-35/140 multipole tube sliding contact lineMulti pole tube sliding contact line collector, also known as receiver, conducts the current on the sliding contact line to the electrical equipment through the collector. The collector is installed on the collector bracket, which is installed on the moving equipment. As the device moves, the carbon brush on the collector moves within the sliding wire, achieving uninterrupted power supply. To facilitate the slip of the collector brush and reduce brush wear, a copper sleeve with a 45 degree chamfer is embedded at the root of the brush; At the same time, in order to make the current collector move flexibly and conveniently, bearings were installed in the guide wheel.

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.

Due to its superior conductivity compared to aluminum, copper bars have been widely used in electrical equipment, especially in complete power distribution systems; Generally, copper bars are used for the A, B, C, N-phase busbars and PE busbars in the distribution cabinet; Copper bars are generally marked with colored letters or coated with colored paint during use. The A-phase copper bar is marked with "yellow" color, the B-phase is marked with "green" color, the C-phase is marked with "red" color, the N-phase is marked with "light blue" color, and the PE busbar is marked with "yellow green" dual color.
Copper bars are mainly used on primary lines (high current phase lines, neutral lines, and ground lines all use copper bars). Copper bars are used to connect primary components with high current on electrical cabinets. For example, a row of electrical cabinets is connected to the main busbar between cabinets, and the main busbar is divided into branch busbars for each electrical cabinet's switch (isolating switch, circuit breaker, etc.). Copper bars come in both tin plated and bare forms. In electrical cabinets, the connections between copper bars are usually treated with tin plating, embossing, or conductive paste. There are heating shrink tubing protections in the vacant areas, and some are coated with insulating paint. The main consideration when using copper bars is the current carrying capacity. Suitable copper bars should be selected according to the current size, and the screws at the connection must be tightened, otherwise there is a possibility of melting the copper bars when the current is high.
