Product Introduction
Multiple copper conductors are arranged in parallel along the length direction and integrally embedded in a semi-enclosed engineering plastic or aluminum alloy housing. The current collector slides inside the housing to draw power, forming a compact multi-pole power transmission system.

Product Feature And Application
Main Features of Multi-pole Enclosed Conductor Rail:
Compact structure with multiple poles integrated into a single housing, saving installation space.
Insulated housing with high protection rating, providing dust resistance, foreign object protection, and shock prevention, ensuring high safety.
Suitable for straight tracks; non-flexible.
Simple installation and maintenance with low failure rate.
Main Applications of Multi-pole Enclosed Conductor Rail:
Primarily used for light to medium lifting equipment, electric hoists, automated production lines, small automated warehouses, and mobile power supply in factory workshops. Suitable for applications with an operating current below 125 A, moderate travel speed, and a relatively clean environment.

FAQ
Q: What is a multi-pole enclosed conductor rail?
A: A compact power supply system in which multiple copper conductors are arranged in parallel and integrally embedded in a semi-enclosed engineering plastic or aluminum alloy housing, with the current collector sliding inside the housing to draw power.
Q: What are the main components of a multi-pole enclosed conductor rail?
A: Housing, copper busbar, enclosed current collector, connector, hanger, end cap, power feed.
Q: What scenarios are multi-pole enclosed conductor rails suitable for?
A: They are suitable for applications with an operating current below 125 A, travel speed ≤ 300 m/min, and a relatively clean environment, such as light to medium lifting equipment, electric hoists, automated production lines, and small automated warehouses.
Q: How do you select the number of poles for a multi-pole enclosed conductor rail?
A: Select based on the equipment power requirements. Common pole configurations are 3-pole, 4-pole, 6-pole, and 16-pole. Three-phase equipment requires 3 poles plus a protective earth conductor; DC equipment is configured according to the positive and negative terminals.
Q: What does daily inspection of a multi-pole enclosed conductor rail include?
A: Inspection of carbon brush wear, dust accumulation inside the housing, looseness of connector bolts, detachment of hangers, and deformation of the housing.
Q: When should the carbon brush be replaced?
A: The carbon brush should be replaced when it wears down to two-thirds of its original length to ensure uniform contact pressure.
