Both enclosed bus ducts and enclosed busbars are collectively referred to as bus ducts, but there are still certain differences between the two. At present, some information network comprehensive buildings adopt centralized power supply, while the power room is set up on one floor, and the information load is on the upper floor. The distance between the power room and the information load is too large, and the number of DC cables used in the information room is huge. To avoid excessive cable laying, it is recommended to use a one-time method to transfer the DC power supply from the power room to the load room side. At this time, a closed bus duct can be used.

It is an effective way to reduce the use of cables, with strong heat dissipation capacity, environmentally friendly products, flexible wiring, and other characteristics. It has practical application significance in comprehensive buildings with centralized power supply mode. Currently, this busbar has been increasingly used in operating rooms. Today we will learn about the differences between these two types of bus ducts. Let's follow Guangdong Cisco General Electric Power Technology Co., Ltd. to learn more.

Enclosed bus ducts can be divided into three types according to insulation methods: air type plug-in bus ducts, dense insulation plug-in bus ducts, and high-strength plug-in bus ducts. Divided by purpose into dense insulation, air insulation, air additional insulation, fire-resistant, resin insulation, and sliding contact busbar trunking. According to its shell material, it is divided into steel shell, aluminum alloy shell, and steel aluminum mixed shell bus duct. According to its structure, it is divided into two types: starting end bus duct, straight through bus duct with socket and without socket, L-shaped vertical (horizontal) bent bus, Z-shaped vertical (horizontal) offset bus, T-shaped vertical (horizontal) three-way bus, X-shaped vertical (horizontal) four-way bus, variable capacity bus duct, expansion bus duct, terminal head, terminal junction box, plug-in box, related accessories and fastening devices of bus duct.

The installation site for enclosed busbars should not exceed an altitude of 2km. The surrounding air temperature should not exceed+40 ℃ or -5 ℃, and the average temperature within 24 hours should not exceed+35 ℃. The relative humidity of the air should not exceed 50% at 40 ℃ and 90% at 20 ℃. The surrounding air should be clean and free of corrosive and insulating gases.

There are other differences between the two types of bus ducts besides their concepts and scope of use. The scope of bus ducts is obviously much larger than that of buses. Bus duct systems are complete three-phase three wire, three-phase four wire, or three-phase five wire feeding and distribution systems composed of more than ten types of bus duct unit structures, plug-in boxes, and other supporting components, while enclosed buses only refer to the bus units in the bus duct system.

The above is about the differences between enclosed bus ducts and enclosed busbars. Once we understand them, we will know the differences between the two. They are used in different situations, and their safety and current transmission are different. In addition, the size of the product is also different. So when we make a purchase, we must ask the manufacturer carefully and then choose the appropriate bus duct equipment based on the usage situation
