Busbar, busbar trunking, and busbar bridge are three things that are often confused. Let CG BUSWAY's brief encyclopedia help you uncover the differences between busbar trunking.

In the field of electrical engineering, a busbar, also known as a busway or busbar, often refers to the busbars or main power lines inside high and low voltage switchgear used to connect multiple electrical circuits. The system uses busbars to install various interface cards and transmit data to the devices connected to these interface cards.

A bus can serve multiple components. The basic operation of a bus typically involves components sending information to the bus in a time-multiplexed manner, after which the bus simultaneously transmits this information to all components receiving it. Control signals generated by decoding the device address given by the CPU determine the routing of the information.

(Busbar: Most commonly refers to the main power distribution bars or feeder lines inside high and low voltage cabinets.)

Busway

The busway is a high-current trunk-type separable power supply system, which mostly refers to intensive busways or enclosed busways, typically consisting of a metal shell (iron or aluminum), conductors (copper bars or aluminum bars), insulation materials, and related accessories. The copper bars inside are closely packed together and can operate safely and stably through insulation treatment.

The busway originated in the United States, was first put into practical use in Japan, and then rapidly spread in developed countries and regions like mushrooms after rain. In recent years, with the extensive construction of infrastructure, the demand for electricity has been increasing. The busway has gradually become a necessary product for high-current transmission systems in industrial plants, high-rise buildings, commercial complexes, rail transportation, and other places.

(The busway is a trunking-style plug-in power supply system for high currents.)

Busbar Bridge

The busway bridge is functionally equivalent to the busway, both serving as high-current conductors. It is a busbar system composed of metal plates (steel or aluminum) as protective shells, conducting bars, insulating materials, and related accessories. It can be made into plug-in closed busways with interval junction boxes or feeder-type closed busways without junction boxes in the middle. There are gaps between the product's conducting copper bars, primarily insulated by air within the busway, hence the busway bridge is also known as an air-insulated busway.

(The busbar bridge is also known as an air-type busbar trunking.)

From the perspective of selecting busway products and the iterative process, busway (compact busway) has superior conductivity, safety, and current-carrying capacity compared to bus ducts (air-type busway), making it an upgraded product.
