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 closed bus duct is generally called the bus duct, that is to say, the closed bus duct is the bus duct of the camisole, or the bus duct is the camisole of the closed bus duct. Enclosed busway and busway all refer to the same thing. The closed bus duct is a bus duct system composed of metal plate (carbon steel plate or aluminum plate), which is used to maintain the casing, conductive discharge, insulation raw materials and related spare parts. It can be made into a wiring bus duct with junction boxes arranged at every distance, and can also be made into an explosion-proof switch enclosed bus without junction boxes in the middle.

Different insulation materials: there is an appropriate gap in the middle of the grounding copper bar of the vapor bus duct, that is, the focus of the insulation layer in the middle of the grounding copper bar is vapor. As everyone knows, the raw material of the insulating layer in the middle of the gathered bus duct (also called closed bus duct in many regions) is the raw material of the analytical chemical insulating layer.

Minhang district oil-immersed transformer recycling closed bus duct, collectively referred to as the bus duct. Enclosed bus duct and bus duct all refer to the same item. The closed bus duct is a bus duct system composed of metal plate (carbon steel plate or aluminum plate), which is used to maintain the casing, conductive discharge, insulation raw materials and related spare parts. It can be made into a wiring enclosed bus with junction boxes at every distance, and can also be made into an explosion-proof switch enclosed bus without junction boxes in the middle. In the intelligent management system of the power supply and distribution system of high-rise buildings, the main line of the power supply and distribution system plays a particularly critical role, just like the pulmonary artery in the body, once the obstruction occurs, it will cause important results. Therefore, the manufacturing, establishment and scientific research institutes have been making every effort to improve the stability of the main line of the power supply and distribution system, and then write down the new materials with convenient installation and operation, high quality and low price, and stable characteristics.

Busway is a kind of closed metal industrial equipment composed of copper and aluminum busway, which is used to disperse system components and distribute high power. Busway is an effective substation equipment, suitable for high-rise buildings and small and medium-sized production plant economy, substation equipment fair and reasonable. Because of the continuous growth of functional losses in various industries, traditional cables as power transmission and distribution conductors have been unable to meet the requirements of large current transmission and transformation systems. The parallel calculation and application of several cables makes it more and more difficult to assemble and connect on the spot. As a new type of substation equipment line, the bus duct selects new technology application, new technology, new technology and new technology, which greatly reduces the power circuit resistor and heating at the middle of the bus duct and the support point. The use of high quality insulation materials can enhance safety performance and reliability.
