Briefly describe the application and use of trolley wires

How to use slide wire? Where is the trolley line applied? What is his composition? With these questions, we look down together. The trolley wire device consists of three main components of the sheath, the conductor and the power receiver, and some auxiliary components.

1. Sheath: It is a semi-closed tubular tubular component that is the main part of the trolley wire.

2, conductor: The main material is copper, according to its cross-sectional area commonly used 10 square, 16 square, 25 square.

3. The receiving device is a group of brush housings running in the conduit. It is driven by a fork mounted on the electricity-consuming mechanism to run synchronously with the electricity-consuming mechanism. The energy passed through the guide rail and the brush can be pumped to the motor or Other control elements.

(II) Product Characteristics 1. Safety: The housing of the power trolley line is made of high-insulation engineering plastic. Enclosure protection grade can be up to IP13, IP55 according to need, can protect against rain, snow and freezing attacks and hanging objects touch.

2. Reliable: The power transmission rail has excellent electrical conductivity, rapid heat dissipation, high current density, low impedance, and low line loss. The brush is made of metal graphite material with high electrical conductivity and high wear resistance. The loader moves flexibly with good directional performance and effectively controls the contact arc and string arc phenomenon.

3. Economy: The structure of the power supply trolley line device is simple, and a copper row with high current density, low resistivity, and low voltage loss is used as the conductive body. It can save about 6% electricity, realize the plastic substitution of steel, plastic generation of copper, novel design, no other insulation structure, no compensation line, installed on the same side of the crane control room, saving installation materials and expenses, its comprehensive cost and steel The slide lines are roughly the same.

4. Convenient: The power-slip contact device integrates the multi-level busbars in a single duct, and the assembly is semi-simple. Its fixed brackets, connecting clips and suspension devices are all supplied with common parts. It is also very convenient for assembly and disassembly, adjustment and maintenance.
