Ordinary dense bus duct is a device for power transmission and distribution, suitable for power supply and distribution systems such as DC three-phase three-wire, AC three-phase four-wire, and three-phase five-wire. Its rated voltage can reach 1000V, the rated working current range is between 100 and 6300A, and the frequency covers 50 to 60Hz. This product is widely used in industrial plants, hospitals, shopping malls, high-rise buildings and other places with its high efficiency, safety and reliability.

Ordinary intensive bus duct

What is the difference between intensive bus duct and closed bus duct

Dense bus duct, a kind of closed bus duct. At present, the bus bar bridge is divided into several generations. The first generation is called bus duct and the second generation is called bus duct. All bus duct are closed, including dense bus duct, air bus duct, fire safety bus duct, fire prevention bus duct, pouring bus duct and so on.

Trunking length considerations for dense busbars

Compared with the traditional wire and cable paving method, the dense bus wire slot has many prominent advantages. Such as small size, compact structure, small footprint; large transmission current, can be very easily according to the bus slot plug-in power switch box out of the switching power supply support system; high-quality raw material selection, superb design, high mechanical and electrical engineering characteristics, excellent chassis grounding device, safety factor and stability. Therefore, it is widely used in the world of high-rise residential and high-rise residential industrial building distribution room on the main line. Dense bus threading is not as casual as the air bus duct leading out of the supporting power circuit, but it has excellent flame retardancy.

Installation Process and Common Problems of Common Box Enclosed Bus

Installation process and common problems of common box enclosed bus: including isolated phase enclosed bus, common box (including common interval phase) enclosed bus and cable bus, which are commonly used in power stations, substations, industrial production and civil switching power supply wires. Today, we talk about the installation process and common problems of the enclosed bus.

Two kinds of installation of intensive bus duct

1. intensive busway vertical installation. 1. Accurate measurement According to the position of the embedded hole of the wooden floor, connect two galvanized angle steel support frames and dense bus grooves with bolts, then cover the anti-seismic torsion spring and sealing ring with the bolts brought by the distributor, tighten the nut, and then fix it on the bad steel support frame. The total number of torsion spring support point groups shall be specified according to the type and volume of the dense bus duct.

Closed bus duct is what does that mean?

There are two types of closed bus duct. A closed bus duct cable has a large current carrying capacity but is not resistant to high temperatures. It only works at 200°C and is generally installed on the line to transport the working voltage. This type of busway is also called the gathering type closed busway; another kind of closed busway high temperature, generally in 700~1000 ℃ operating temperature specification, can maintain 1.5 hours of power transmission and transformation operation, the cable carrying capacity of up to 5000A. This type of closed bus duct is called fire safety closed bus duct. The difference between the fire-proof closed bus duct and the aggregate closed bus duct is a part of the casing. The fireproof and safe enclosed busway casing is coated with fireproof industrial paint, while the surface of the clustered enclosed busway is sprayed with electrostatic powder, which is smooth and has strong adhesion of the anti-corrosion layer. Therefore, when selecting bus duct in the design of safety fire line and EPSEPS emergency power supply line scheme, the closed bus duct shall be fired.

The use of bus duct advantages

With the development of social economy and science and technology in all walks of life, the continuous emergence of social engineering facilities and equipment, the continuous increase of electricity consumption in all walks of life, especially the increasing number of workshops and factories, the supply and demand of electricity can not meet the demand, which brings a lot of inconvenience to the engineering and plant construction.
