Product Description
Sliding Contact Line (Conductor Bar) System
Sliding contact lines, also known as conductor bars, are power transmission systems designed to supply electricity to moving equipment. The main types include single-pole aluminum conductor bars, single-pole copper conductor bars, multi-pole safety conductor bars, and steel conductor bars. Among these, single-pole conductor bars, multi-pole tubular conductor bars, and seamless conductor bars are categorized as safety conductor bars, while steel conductor bars are classified as non-safety conductor bars.
Functionality and Design
Sliding contact lines are essential for providing continuous power to mobile equipment, which frequently changes position. The system consists of multiple conductors laid parallel to the movement track of the equipment, connected to a power source. Mobile equipment is equipped with current collectors that draw power from these conductors. As the equipment moves, the current collectors move synchronously, continuously supplying power to the equipment, enabling uninterrupted operation. The sliding contact line system includes three main components: the sheath, conductors, and current collectors, along with auxiliary components.
1. Sheath: This semi-enclosed tubular component is the main body of the sliding contact line. It can house 3-16 conductors, which are electrically insulated from each other to ensure safety and prevent electric shock during maintenance. The sheaths can be produced in varying lengths and shapes, including straight and curved configurations, according to specific needs.
2. Conductors: Primarily made of copper, common sizes include 10mm², 16mm², and 25mm² cross-sectional areas. These conductors are embedded within the sheath to provide power.
3. Current Collectors: These consist of a set of brush holders running inside the sheath, driven by a fork or towing chain attached to the mobile equipment (e.g., cranes, trolleys, electric hoists). They synchronize with the equipment's movement, transmitting power from the conductors to the motor or control elements. The number of brushes in the collector matches the number of conductors in the sheath.
Product Features
1. Safety: The sheath is made of high-insulation engineering plastic, offering protection levels up to IP13 or IP55, safeguarding against rain, snow, ice, and accidental contact. The system's insulation ensures no harm to maintenance personnel touching the exterior.
2. Reliability: The conductors have excellent conductivity and heat dissipation, with high current density and low impedance, resulting in minimal line losses. The brushes, made from high-conductivity, wear-resistant metal graphite, ensure flexible and reliable operation.
3. Economy: The system features a simple structure with high current density and low resistance, reducing voltage loss and saving approximately 6% in energy. The use of plastic in place of steel or copper minimizes the need for additional insulation or compensation lines, reducing installation materials and costs.
4. Convenience: The multi-conductor system is housed within a single sheath, simplifying assembly. Standardized brackets, connection clips, and suspension devices make installation, adjustment, and maintenance straightforward and efficient.
Particularly, the single-pole H-type safety conductor line has significant improvements in protection level and insulation, ensuring safe and reliable operation. These safety conductor lines are suitable for dusty and humid environments and can be equipped with dust seals and hand protection when the contact line is close to personnel (e.g., in applications like Akapp). The current collector operates at speeds below 300 meters per minute.
This comprehensive and efficient power supply solution ensures reliable and safe operation for a wide range of mobile equipment in various industrial settings.

Installation
The Single-Pole Conductor Bar System can be installed vertically or horizontally, on both straight and curved tracks. It is suitable for outdoor use with a protective cover that offers UV and impact resistance. For high-temperature environments (-40ºC to 115ºC), customized protective covers are available to fit various conductor bar sizes.
Applications
This system is designed with advanced technology, expert craftsmanship, and optimal design. It is suitable for a wide range of applications, including machinery works, small steel factories, low-power hoisting, cranes, monorails, electric hoists, electric tools, and stacking systems. It is particularly well-suited for use in the lifting industry, where ambient temperatures are below 55ºC.
Packing and Delivery
- Packing: Accessories are packed using PE film or according to customer specifications. Electric parts are secured in high-quality plywood crates to minimize distortion during transport. Standard packaging involves wooden boxes that are fumigated to ensure safety and compliance.
- Delivery: Products are typically transported in containers by sea, focusing on cost reduction and safety maintenance.
The Single-Pole Conductor Bar System offers a reliable, efficient, and versatile power supply solution for various industrial applications, ensuring stable and continuous operation with minimal maintenance and exceptional performance.
