What is Bus duct in electric power distribution :

Bus duct is a duct Container including either copper or aluminum busbar for the purpose of conducting a substantial current. In electric power distribution, a bus duct conducting electricity to power cables or cable bus.

Why bus-duct is used instead of cable?

Installing power cables is more difficult and takes a lot more manpower and more time on site and can only be done by highly specialized electricians. However, bus-duct can be installed quickly, efficiently and with ease resulting in a significant reduction in on-site costs. Busbars also have a limited increase in reactive power to operate compared to cable systems. Their design also reduces the distance between conductors as well as resistance and Reduces voltage loss. is one of the most trusted manufacturing company for air insulated busduct upto 6300A 65KA fault level. Air insulated busduct is more cost effective and reliable than sandwich duct.
Air insulated Bus-duct is mostly used for industrial and commercial sites like malls, multiplex, hospital, solar power plants for effective and efficient supply of electricity. Air insulated busduct is approved by CPRI and major electrical consultant in india.
