What Is a Busway System?
A busway system, also commonly called a busbar trunking system, is an enclosed electrical power distribution system used to transmit and distribute power through copper or aluminum bus conductors.
Instead of using large bundles of conventional power cables, a busway system uses prefabricated sections that connect together to form an organized electrical distribution route. Depending on the project design, busway can be used for main power transmission, vertical distribution, branch distribution and equipment connection.
A typical busway system may connect:
Transformer → LV Switchgear → Main Busway → Plug-in / Rising Main Busway → Plug-in Box / Distribution Board → Electrical Loads.
Different busway types are used for different applications. Feeder busway is mainly used between major electrical distribution points, plug-in busway provides flexible branch distribution, and rising main busway is used for vertical electrical distribution in multi-storey buildings.
Busway systems can be applied in industrial facilities, commercial buildings, high-rise buildings and other projects where reliable and organized power distribution is required.
Frequently Asked Questions
Frequently Asked Questions
1. Is busway the same as busbar trunking?
Yes. The terms are commonly used for enclosed bus conductor systems used for electrical power distribution.
2. Can busway be installed vertically?
Yes. Rising main busway is commonly used for vertical electrical distribution in multi-storey buildings.
3. What conductor materials are available?
Yongjin’s YJC compact busway documentation includes both copper and aluminum conductor configurations.
4. Can busway connect to transformers and LV switchgear?
Yes. Busway systems can use starting and connection sections for transformer and LV switchgear interfaces.
5. What information is needed before requesting a quotation?
Useful starting information includes the SLD, electrical layout, rated current, route information, equipment positions and project specification.
