Air-Insulated Busway System

the air-insulated busway system, also known as an air-insulated enclosed busway, uses the air gaps between conductors as the primary insulation medium. Insulating support blocks are installed between the copper busbars to maintain safe phase spacing, while the entire conductor assembly is enclosed within a protective metal housing.

Designed as a cost-effective solution for low-voltage power distribution, the system supports both three-phase four-wire and three-phase five-wire configurations. It has a rated voltage of 690 V and a standard rated current range of 250 A to 1600 A, making it suitable for general industrial plants, commercial buildings, and conventional power distribution trunk lines.

Air-Insulated Structure

The system uses controlled air gaps between phase conductors as the main insulation method, with insulating support blocks providing additional separation and mechanical positioning.

Reliable Electrical Isolation

Insulating supports maintain stable spacing between copper busbars, helping prevent phase-to-phase contact and ensuring reliable electrical insulation during operation.

Metal Enclosed Protection

The conductor assembly is completely enclosed within a metal housing, providing mechanical protection for the internal busbars and insulating components.

Multiple Distribution Configurations

The system supports both three-phase four-wire and three-phase five-wire power distribution configurations, making it adaptable to different low-voltage electrical systems.

Wide Current Range

With a rated voltage of 690 V and current ratings from 250 A to 1600 A, the air-insulated busway meets the power transmission requirements of conventional industrial and commercial projects.

Cost-Effective Power Distribution

Its simple and practical structure provides reliable power transmission while maintaining competitive overall costs, making it suitable for factories, buildings, and other general-purpose low-voltage distribution applications.
