When choosing a bus duct,it is also necessary to follow relevant principles,not only to consider the quality and price of the bus duct,but also to understand one's own needs and choose the accurate type for oneself.In terms of types,bus ducts are divided into dense and enclosed types,which means that everyone needs to distinguish between different types of bus ducts because their usage is different.Plug in bus duct is used for transmitting electrical energy in three-phase four wire and three-phase five wire distribution systems with AC 50Hz,rated voltage of 380V,and rated current of 250-3150A.Suitable for various occasions such as workshops,renovation of old enterprises,laboratory buildings,high-rise buildings,etc.

　　There are also different models of bus ducts,and the working efficiency of different bus ducts varies.It is important for everyone to know their own needs and choose a suitable bus duct to ensure smooth operation.Otherwise,if the model is different and incorrect,the bus duct may not work properly.Compared with traditional cable distribution methods,it has the advantages of small size,high current transmission,safety and reliability,easy disassembly and assembly,no interference between infrastructure and distribution construction,and can be reused with a single investment.It is an ideal distribution product.The basic structure of the busbar is enclosed,consisting of a conductive copper bar wrapped in high-quality insulation material,a cold-rolled steel plate shell treated with electrostatic spraying on the surface,and accessories such as insulation screws.Busbar direction changing joint(elbow)is used for connecting and changing the direction of distribution busbars during horizontal and vertical installation.

　　Bus duct straight bus unit,in conjunction with bus direction changing joint,is used to transport power to electrical equipment.Plug in box,used to lead out power branches from the busbar.The starting busbar is a power supply introduction unit that can be directly connected to transformers or low-voltage distribution panels.Variable capacity section refers to the transition section when converting the capacity of the busbar.Expansion joint is a functional unit designed to absorb thermal expansion deformation caused by long-term operation.The intermediate inlet box is suitable for various occasions.Generally,in the case of a long busbar connection length,it will greatly improve the situation of large voltage drop loss from single end power supply to the end.Terminal cover,installed at the terminal of the busbar(or each branch),to prevent external contact with live parts.

　　In the production process of busbar trunking,the important raw material is the conductor.The selection of conductors directly affects the price of bus ducts;The function of conductors is directly related to the performance indicators of bus ducts.The selection of internal conductors is particularly important for a qualified busbar trunking product to meet user requirements and fulfill its transmission and distribution functions.The conductor used is high-quality T2 electrolytic copper,and its motor performance is much better than ordinary brass and purple copper.
