Busway systems are essentially made of copper or aluminum conductors, supported by special insulating materials, and encased in aluminum or steel shells for dense high-current transmission. They are commonly used in factory power supply systems, building power supply systems, data center power supply systems, residential power supply systems, and commercial power supply systems.

Busbars have significant advantages over ordinary cables, such as high current carrying capacity, low transmission voltage drop, low power loss, simple connection and branching, easy installation and maintenance, and a long service life. They are an ideal device for high current transmission.
