DMHP-4-10/50 multipole tube safety sliding contact wire

DMHP-4-10/50 multipole tube safety sliding contact wireMulti 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.

DMHP-4-10/50 multipole tube safety sliding contact wireProduct Features

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.

We must be very familiar with the metal element copper, and the most common one is the copper wire in electrical wires. However, there are many varieties of copper, such as red copper, bronze, brass, white copper, etc. Although these are all classified as similar elements, there are still differences between each type. Today, let's share with you some tips on how to differentiate between red copper and brass. What is red copper? Red copper, also known as purple copper, is a type of copper element named after its surface color of purple red. Because it also has a rose red color and a purple surface after forming an oxide film, it is generally also known as purple copper. It is copper containing a certain amount of oxygen, hence also known as oxygen-containing copper. Red copper is an industrial pure copper with a melting point of 1083 ℃ and a relative density of 8.9, which is 5 times that of magnesium metal and has no isomeric changes. The mass of the same volume is about 15% heavier than ordinary steel, and many products require excellent conductivity, such as cables, wires, electric brushes, and special electrical erosion copper for spark discharge.
