Busbar trunking, also known as busway or bus duct, is an electrical distribution system commonly used in industrial and commercial buildings to transmit power from the main source to various distribution points. It consists of a rigid metal enclosure, typically made of aluminum or copper, which houses conductive bars or busbars. These busbars act as conductors for electric power and are supported by insulating materials to ensure safety and reliability.
The main features and components of a busbar trunking system include:
- Busbars: These are the primary conductors that carry electrical current. They are typically made of aluminum or copper due to their excellent electrical conductivity properties. The busbars are designed to handle high current levels and are usually arranged in a compact, rectangular cross-section within the enclosure.
- Enclosure: The busbars are enclosed within a protective housing made of metal or non-metallic materials. The enclosure provides mechanical protection, insulation, and acts as a barrier against external elements, preventing accidental contact with the live components.
