Industry Solutions FAQ

What exactly is a busway? Industrial power distribution explained.

A busway is an enclosed, factory-assembled electrical distribution system combining busbars, insulation, protective housing and accessories. It collects and distributes power efficiently, with capacities of up to 6300A or more, making it ideal for high-rise buildings, industrial corridors, and data centres. The enclosure prevents dust, moisture and impact, while flame-retardant insulation ensures that no toxic gases are emitted in the event of a fault. All ratings comply with industry standards to ensure safe, continuous operation.

Busway vs. cable tray: Key technical differences and advantages

Busways offer higher ampacity, enclosed safety and faster installation than cable trays, particularly in confined spaces. However, cable insulation can degrade over time, emitting toxic smoke in the event of a fault. Busway allows infrared inspection of joints for predictive maintenance. It also complies with industry standards for fire and temperature performance, whereas traditional cables only comply with installation rules. For long vertical risers, busway can reduce shaft width by up to 50% and eliminate hidden failure points.

The main types of busway are compact, air-insulated and cast-resin.

Compact: Tight bars with flame-retardant insulation. Ideal for narrow shafts and IP65 environments. Saves 50% of the space required by air-insulated types.

Air-insulated: Ideal for dry, well-ventilated industrial corridors.

Cast-resin: Ideal for IP68 submersible or coastal environments.

Select copper for high-performance applications or aluminium for cost-sensitive projects.Fire ratings follow building fire codes.
