It is necessary to stick 2*30 insulation double-sided tape at the end of the dense busbar side panel to maintain the insulation layer of the busbar from being damaged by the end of the side panel.The insulation double-sided tape should extend 5mm beyond the end of the side panel,and the length should be the same as the height of the side panel.In the middle of the side panel,one insulation tape should be stuck every 300mm,and the length should be the same as the height of the side panel.Before assembling the dense busbar trunking,the holes on the busbar side and cover plate of the unit should be calibrated in advance.If the holes are not matched,they should be promptly returned to the sheet metal area for drilling and deburring.Drilling operations are prohibited in the busbar assembly area.

　　During the assembly process,if the ends of the busbar are not aligned with the outer shell,use a wooden or rubber hammer to gently strike and adjust slowly.Do not use metal objects or force to strike.If the lengths of the busbars in each phase are different,adjust the distance between the two ends to evenly distribute the error.Do not accumulate errors at one end.After the fixing of the busbars and side plates in the dense busbar trunking is completed,it is necessary to carefully check whether there are screws,nuts,or other debris inside the busbar trunking to ensure that all debris is removed before covering the cover plate.The bolts on the busbar side and cover plate should be locked tightly,and the pressure should be uniform.There should be no missing bolts on all bolts.

　　The inspection of dense busbar ducts is particularly important due to the layout characteristics of dense busbars themselves.Each functional unit must undergo strict inspection through the busbar inspection line before being stored.Products that fail the inspection cannot be stored.In addition to inspecting the appearance of the air type busbar,it is important to conduct a voltage withstand test of 3750V for 1 minute on each unit of the dense busbar.Only products that pass the test can be stored,and products that fail the test can be returned to the installation process.After dismantling,gross defects and their causes can be identified,and after rework and disposal,a voltage withstand test can be conducted again until they pass before they can be stored.

　　The installation of dense busbar trunking can be directly connected from the transformer to the low-voltage distribution cabinet,or directly connected from the low-voltage cabinet to the distribution system as a distribution main line.Bus ducts have the advantages of small size,compact structure,high transmission current,and easy maintenance.In short,it refers to the power supply and distribution equipment in industrial and mining areas,enterprises,and high-rise buildings,which play a role in transportation.However,if water enters the dense busbar trunking due to natural or human factors.When dense bus ducts pass through floors,water accumulation may occur due to various reasons such as production or roof leakage,which will leak down along the bus ducts passing through the floors,causing water to enter the bus ducts and reducing their insulation.
