The Air Insulated Copper Busway manufactured by Qingdao Fenghua Electric Appliance Manufacturing Co., Ltd. is a high-end power transmission product specifically engineered for industrial and commercial low-voltage distribution systems. By adopting high-quality copper conductors with superior electrical conductivity, the system ensures efficient power transmission with minimal resistance and reduced energy loss. This advanced design enables the busway to effectively replace traditional cable distribution systems while providing improved performance and reliability.
Air Insulated Copper Busway is a modern busbar trunking system designed for low-voltage power distribution, using high-purity copper conductors to transmit electrical current and air as the primary insulation medium between conductors. This structure allows the system to safely deliver large electrical loads with excellent heat dissipation and electrical reliability. Compared with traditional power cables and ordinary busbars, an air insulated copper busway provides higher conductivity, lower energy loss, easier installation, and longer service life, making it an ideal backbone power transmission solution for modern electrical infrastructure.
With its air insulation structure, the busway offers excellent thermal management and electrical insulation performance. The product features high current-carrying capacity, strong insulation reliability, high temperature resistance, and long service life, making it suitable for demanding power distribution environments such as manufacturing plants, large commercial buildings, data centers, and infrastructure projects.

The Air Insulated Copper Busway transmits power through conductive copper busbars and air insulation.
The workflow is as follows:
Power enters the busbar trunking from the transformer or distribution cabinet.
High-current transmission occurs through the copper busbars.
Safe air gaps are maintained between each phase busbar.
Power is supplied to the equipment through branch plug-in units.
Due to the low resistance of copper conductors, power loss is reduced and system efficiency is improved.
