Electric power distribution is the final stage in the delivery of electric power. it carries electricity from the transmission system to individual consumers. Often several customers are supplied from one transformer through secondary distribution lines. There are Several electrical equipment are involved in Power Distribution. Transformers, Switchgear, Bus Ducts, etc. are main contributors at this final stage of electric distribution.
A key part of electrical power distribution is bus duct. Also called busway, bus duct provides an alternative means of conducting electricity. Bus duct is used in commercial and industrial settings to conduct electricity to power cables or cable bus. Structurally, a bus duct is a sheet metal duct containing either aluminum or copper busbars (metallic strips or bars that conduct a substantial electrical current) in a grounded metal enclosure. Bus duct is easy to maintain and flexible, helping to accommodate changing load requirements.
