Since the 1990s, with the continuous and in-depth development of the market economy, various new technologies have been continuously introduced and developed, new products have emerged in an endless stream, and bus ducts are also widely used in construction projects. So, what is the purpose of bus duct?
·What is the purpose of bus duct - selection
1. Types, performance and advantages of bus duct
Closed bus duct (referred to as bus duct) is a bus system composed of metal plates (steel plates or aluminum plates) as protective shells, conductive rods, insulating materials and related accessories. It can be made into a plug-in closed system busbar with junction boxes inserted at intervals, or a variety of feed-in closed busbars without a junction box in the middle. In the power supply system of high-rise buildings, power lines and lighting lines are usually installed separately. The main power line is a busbar, which is installed vertically one or more times along the wall of the electric shaft. According to the purpose, the bus ducts are generally produced bus ducts, straight bus ducts (with or without jacks), L-shaped vertical (horizontal) elbow bus bars, Z-shaped vertical (horizontal) biased bus bars, T-shaped vertical (horizontal) triple Input busbars, Bus ducts can be divided into air plug-in bus ducts, sealed and insulated plug-in bus ducts and high-strength plug-in bus ducts.
Air plug-in busbar duct (BMC). Since the connections between busbars are copper connections, they are prone to moisture and oxidation in the south, resulting in poor contact between busbars. In addition, the volume between the joints is too large, the size requirements of the transverse busbar sections are inconsistent, and the appearance is unsightly.
·What is the purpose of bus duct - comparison and analysis
1. Comparative analysis of the performance characteristics of single-core branch cables and compact bus ducts
The so-called branch cable means that the T-shaped connector of the cable can be installed at the location required by the cable company. It is manufactured in the factory according to a specific process, and the joint part is integrally formed by secondary injection molding of PVC synthetic material. Branch cable products undergo strict electrical and physical performance testing before leaving the factory. They have the advantages of high reliability, sealing and waterproofing, flame retardant and fireproofing, and are cheap and easy to use. The installation and construction period is short and no maintenance is required. Branch cables are divided into single core and multi-core. However, the manufacturing process of single-core branch cables is simpler and the price is lower. Compared with single-core and multi-core cross-section cables, they are lighter in weight, smaller in outer diameter and come in a variety of specifications. Installation and construction are simple. The price of multi-core cables is significantly higher than the sum of multiple single-core single cables of the same cross-section. Therefore, when choosing branch cables, single-core branch cables are generally selected.
Bus duct is divided into two types: dense insulation type and air insulation type. The air-isolated type is light in weight, simple in structure, and relatively cheap; the densely insulated type has good heat dissipation conditions and a large rated current. Bus ducts, typically installed in electrical ducts in high-rise buildings, have a plug-in connector on each floor. The products are produced by bus duct manufacturers, transported to the construction site in sections, and connected with bolts. Therefore, the reliability of busway connectors is greatly affected by human factors, and the reliability of finished branch cables is low. However, the bus duct has large capacity, compact structure and small floor space. Rated current up to 5000A
·What is the bus duct construction plan?
1. Construction preparation
(1) Technical preparation
1. Required equipment and materials
(1) The closed plug-in busbar should have a factory certificate and installation engineering technical management documents. The technical documents should include technical information such as rated voltage, rated capacity, test reports, etc. The model, specification, and voltage level should be designed and developed in compliance with teaching requirements.
(2) Various specifications of steel should have no obvious corrosion. Clamps, various bolts, and washers should meet the design requirements and should be hot-dip galvanized products.
(3) Other materials: anti-corrosion paint, topcoat, welding rods, etc. should have factory certificates.
2. Operating conditions:
(1) Construction drawings and product technical documents are complete.
(2) The installation part of the closed plug-in busbar and the decoration work of the construction are all completed, and the installation of the heating, sanitation, and ventilation system projects is completed. (3) Install electrical equipment (transformers, switch cabinets, etc.) and pass acceptance inspection.
Above is everything in the bus pipe. Bus duct is a power distribution device that can effectively transmit electric current and is particularly suitable for buildings that meet increasingly high requirements. The economic development of large enterprises and factories requires rational wiring.
