Safety conductor rail, also known as: conductor rail, safety slide wire, slide wire. The safety conductor rail is an energy-saving type developed by learning from advanced foreign experience and combining with national conditions. It has safety, reliability, and excellent mechanical and electrical properties, and is easy to install and maintain. The phase spacing is 80mm, and the protective shell is made of two materials: engineering plastic and aluminum-plastic alloy. The conductor is aluminum alloy (with embedded stainless steel strips) 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 conductor rail is used to supply power to moving equipment. It consists of two parts: the slide rail (fixed part, connected to the power supply, usually composed 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 track and contact the copper strip to collect electricity, used to connect with the moving motor).
Commonly used are safety conductor rails (tubular, enclosed), single-pole combined conductor rails, rigid conductor rails, multi-level tubular safety conductor rails, seamless safety conductor rails, cable safety conductor rails, I-beam cable trolleys, etc. They have made great improvements in protection level and insulation, and are safe and reliable.
The quality of safety conductor rails 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 conductor rail 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 the conductor rail -- after the length exceeds 100 meters, expansion must be considered.
5. Voltage drop problem -- the voltage drop varies according to the length of various copper strips.
1. Product structure: The M-type conductor rail consists of a guide rail, protective sheath, current collector, hanger, connector, fixing clamp, end cap, etc. According to user requirements, expansion sections (thermal compensation devices), maintenance sections (isolators), etc. can also be configured.
2. Guide rail and protective sheath: The guide rail is made of aluminum alloy profile with good conductivity and strong adaptability to the environment (grade 6063, state T5). A "V"-shaped stainless steel groove is embedded in the lower part of the guide rail to ensure that the carbon brush of the current collector slides along the groove with wear resistance, stability, and good contact. The guide rail is generally fixed at 6 meters. The protective sheath is made of engineering plastic with toughness, wear resistance, anti-aging, and flame retardant properties, providing good insulation protection for the guide rail and ensuring personal safety.
3. Current collector: The current collector is of a support type structure and is the main component that supplies 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 serving as 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 that also serves as a power supply can introduce the power incoming line at the port, and is fastened together with the connector pressure plate and bolts.
5. Hanger, fixer, and end cap: The hanger is a special part for hoisting and fixing the conductor rail 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 caps are installed at both ends of the guide rail for insulation protection. The hanger and end caps are made of engineering plastic.
6. Expansion section (thermal compensation device): The expansion section is also called an expansion joint or thermal compensation device. It consists of connector pressure plates, compensating aluminum or copper plates, leads, etc., and the shell is made of engineering plastic. When the guide rail expands and contracts due to temperature changes, the expansion joint adjusts the 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 sleeve. It is selected according to user needs and is mainly convenient for maintenance of conductor rails, moving equipment, etc.
Safety conductor rail: For dusty, humid and other environments, it can be equipped with dust-proof sealing strips and hand protection (hand protection is required when the conductor rail is very close to people). The running speed of the current collector is less than 300 meters/minute.
Single-pole combined safety conductor rail: Easy to install, fast speed, speed can reach 500 meters/minute (imported conductor rails can achieve this).
Rigid safety conductor rail: Used for high current equipment, current can reach several thousand amperes.
Tubular conductor rail: Can be combined according to different numbers of poles, and the current can also reach thousands of amperes.
