Multi-level tubular safety slide contact wire wholesale
Darui Electric recommends
Safety slide contact wire, also known as: slide contact wire, safety slide wire, slide wire. Safety slide contact wire is an energy-saving slide contact wire developed by learning from advanced foreign experience and combining with national conditions. It has safety, reliability, and excellent mechanical and electrical performance, and is easy to install and maintain. The phase spacing is 80mm, the protective shell is made of two materials: engineering plastic and aluminum-plastic alloy. The conductor is aluminum alloy (with stainless steel strips embedded) or pure copper. It is not affected by rain, snow, frost, and is suitable for harsh environments such as open air, water mist, acid mist, and conductive dust. For specifications below 300A, circles and arcs of various radii can be made according to user needs.
Safety slide contact wire is used to supply power to moving equipment. It consists of two parts: the slide rail (fixed part, connected to the power supply, usually made of single lengths of 4m/piece or 6m/piece connected together), and the current collector (sliding part, which can slide on or inside the slide rail and contact the copper bar to collect electricity, used to connect with the moving motor).
Commonly used are safety slide contact wire (tubular, enclosed), single-pole combined slide contact wire, rigid slide contact wire, multi-level tubular safety slide contact wire, seamless safety slide contact wire, cable safety slide contact wire, I-beam cable trolley, etc. They have made great improvements in protection level and insulation, and are safe and reliable.
The quality of safety slide contact wire can be measured according to the following standards:
1. Carbon brush service life - it is a consumable item, and the travel distance affects the equipment maintenance cycle.
2. Quality of the slide contact wire shell - applicable temperature, environment, etc.
3. Performance of the current collector - mainly from 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 slide contact wire - when the length exceeds 100 meters, expansion must be considered.
5. Voltage drop problem - the voltage drop varies according to the length of various copper bars.
1. Product structure: The type slide contact wire consists of guide rail, sheath, current collector, hanger, connector, fixing clamp, end cover, etc. According to user requirements, expansion section (thermal compensation device), maintenance section (isolator), etc. can also be configured.
2. Guide rail and sheath: The guide rail is made of aluminum alloy profile with good conductivity and strong environmental adaptability (grade 6063, state T5). The lower part of the guide rail is embedded with a "V"-shaped stainless steel groove to ensure that when the current collector brush slides along the groove, it is wear-resistant, stable, and has good contact. The guide rail is generally fixed at 6 meters. The sheath is made of engineering plastic with toughness, wear resistance, anti-aging, and flame retardant properties, which provides good insulation protection for the guide rail and ensures personal safety.
3. Current collector: The current collector is a support-type structure and is the main component for supplying power to moving equipment. It consists of special carbon brushes, terminal posts or terminals, plastic protective cover, support arm, etc. It applies appropriate contact pressure, slides smoothly along the guide rail, and supplies power to the equipment. When the equipment needs maintenance, the carbon brush of the current collector can be pulled away from the guide rail to cut off the power, ensuring safety and convenient operation.
4. Connector (also power supply): The connector is specially used for end connection between guide rails. It is reliably connected by pressure plates and bolts, and the shell is protected by engineering plastic. The protective sleeve also serves as a power supply, and the port can introduce the power incoming line, which is fastened together with the connector pressure plate and bolts.
5. Hanger, fixer, and end cover: The hanger is a special part for hoisting and fixing the slide contact wire guide rail. The fixer is a device that limits the guide rail at the bracket. When the guide rail expands and contracts due to temperature changes, it guides the guide rail to extend to both sides of the fixer. The end cover is installed at both ends of the guide rail to provide insulation protection. The hanger and end cover are both made of engineering plastic.
6. Expansion section (thermal compensation device): The expansion section is also called expansion joint, thermal compensation device, etc. It consists of connector pressure plates, compensation power supply aluminum plates or copper plates, leads, etc., and the shell is engineering plastic. When the guide rail expands and contracts due to temperature changes, the expansion joint adjusts its gap to avoid deformation of the guide rail. Generally, when the workshop length exceeds 200 meters, one set is configured for every additional 100 meters.
7. Maintenance section (isolator): The maintenance section is made of connector pressure plates and high-strength insulating materials, with an engineering plastic shell as the protective cover. It is selected according to user needs and is mainly convenient for maintenance of slide contact wire, moving equipment, etc.
Safety slide contact wire: used in dusty, humid environments, can be equipped with dust-proof sealing strips and hand protection (hand protection should be configured when the slide contact wire is very close to people). The running speed of the current collector is less than 300 meters/minute.
Single-pole combined safety slide contact wire: easy to install, fast speed, speed can reach 500 meters/minute (imported slide contact wire can achieve).
Rigid safety slide contact wire: used for high current equipment, current can reach several thousand amperes.
Tubular slide contact wire: combined according to different pole numbers, current can also reach thousand amperes.
