Safety trolley wire quality can be measured according to the following criteria:
1, carbon brush life - is consumables, driving distance affect the equipment maintenance cycle.
2, the quality of the line contact shell - applicable temperature, environment and so on.
3, collector performance - mainly from the wheel life, turning wheel design and whether the collector meets a variety of environments.
4. Scaling line expansion problem - The expansion problem should be considered after the length exceeds 100 meters.
5, voltage drop problem - according to the length of a variety of copper strip voltage drop varies.
Safety slide line is also called: trolley line, safety slide line, slide line. The safe trolley line is an energy-saving trolley line developed based on the advanced experience of other countries combined with national conditions. It is safe, reliable and has excellent mechanical and electrical properties, and is easy to install and maintain. The spacing is 80mm. The protective enclosure is made of engineering plastic and aluminum-plastic alloy. The conductor is aluminum alloy (insert stainless steel strip) or pure copper. It is not affected by the rain and snow frost and is suitable for open air, water mist, acid mist, conductive dust and other poor environments.
The safety trolley line is used to supply power to the moving equipment and consists of two parts. The slide rail (fixed part, connected to the power supply, and the regular guide rail is formed by a single length of 4m/root or 6m/root connection), the collector (Sliding part can slide on or within the slide rail and contact the copper strip to take electricity, and the collector is used to connect with the mobile motor).
General use of safety trolley wire (tube type, closed), single-pole combined trolley wire, rigid body trolley wire, multi-stage tubular safety trolley wire, seamless safety trolley wire, cable safety trolley wire, I-shaped Steel cable pulleys, etc., have greatly improved in terms of protection grade and insulation, and are safe and reliable.
Safety slide wire product features:
1. Safety: The housing of the power trolley 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. The product is subjected to a variety of environmental conditions. Good insulation performance, no harm to the maintenance personnel touching the outside of the power transmission conduit.
2. Reliable: The power transmission rail has excellent heat conductivity, high heat dissipation, high current density, low impedance, and small 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.
