During our use,we may find that enclosed busbars sometimes do not maintain pressure.We need to figure out whether it is due to the enclosed busbar duct or the contact problem of the enclosed busbar.Each section of the enclosed busbar consists of three parts:the outer shell,the conductor,and the insulator.The outer shell and the conductor are relatively fixed in position through the insulator.In order to achieve good sealing of the enclosed busbar,the contact surface between the insulator base and the aluminum cover plate of the base is tight,and a circular rubber gasket is added between the two contact surfaces.

　　Due to the long enclosed busbar,it is not possible to weld it directly before leaving the factory.It can only be transported in sections to the site for welding and assembly.Bumps and collisions during the journey can cause deformation of the enclosed busbar,making it difficult to fit tightly during installation.Most power construction companies in China hire local labor for assembly,and these personnel undergo simple training(some even do not receive training at all)and are directly employed.Do not apply glue where it should be applied inside the enclosed busbar,do not install asbestos pads where it should be installed,and do not install sealing rings where it should be installed.The method of installing terminal posts on insulation boards should be used to connect the internal and external wires.In our daily lives,the use of these products actually requires the use of different methods for power transmission.Due to the increasing demand for electricity in residential areas,central business districts,and various manufacturers.

　　For resistors,the requirements should become increasingly low.When choosing different companies for cooperation,various circuit supply problems often arise.When choosing our company,you should first understand that the power consumption of bus ducts will have a great impact on our lives.The larger the resistance,the smaller our electricity consumption may become.So it is necessary to analyze the product for different situations and lower the resistance standard of this product.So this product is a good safety guarantee for bus ducts.

　　Due to the fact that most of the connections of the enclosed busbar are made through welding(including connections from manufacturing plants),and the outer shell of the enclosed busbar is made of aluminum,which is prone to react with oxygen,a dense and difficult to melt oxide film is formed on its surface,and the specific gravity of the oxide film is also high,making it difficult to float out of the molten pool and form weld slag inclusions;In addition,liquid aluminum can dissolve a large amount of hydrogen gas,while solid aluminum hardly dissolves hydrogen gas.Therefore,when the melted weld metal is rapidly cooled and solidified,hydrogen gas cannot be released in time,and it is easy to accumulate and form pores in the weld seam;Factors such as humid welding environment can also affect the sealing performance of the welding joint.
