2. Check whether the conductor and insulation sheet are damaged and whether the surface of the conductor is smooth. The end of the conductor is coated with lubrication Agent. If foreign objects are found, they must be removed immediately. To prevent moisture from seeping in, it is necessary to ensure that the sealing rubber ring at the broken end is installed correctly and reliably.

4. Connect the two busbars by sliding, and place the installation ruler (whose size should be different from the busbar current) on Be careful not to compress the insulated rubber hose between the two busbars until they collide The position must be correct.

5. Loosen the connecting bolts and washers, thick connecting plates and spring washers, and apply silicone sealant around the bolts.

母線槽安裝完工后，必須全線檢查各個連接點及外殼接地線是否牢靠和遺漏，按電氣規范要求，進行性能檢查。

母線槽水平安裝或垂直豎井安裝后，要求母線槽的水平直線度及垂直度不得超過±5/1000。

母線槽全線安裝完畢，供電端及分支引線全部切斷，不與電器設備相連，常溫狀態下，用1000V 兆歐表測量其相與相，相與地的絕緣電阻≥ 20MΩ，若溫度在30° C 以上，相對濕度在90% 以上時其絕緣電阻不小于0.5MΩ，經過烘烤后絕緣電阻能上升，絕緣耐壓每分鐘2000V 并且無閃烙現象，則可連接通電試運行。

After the installation of the bus duct is completed, it is necessary to inspect all connection points and the grounding wire of the shell for reliability and omissions, and conduct a comprehensive performance check according to electrical specifications.

After the horizontal installation or vertical shaft installation of the bus duct, it is required that the horizontal straightness and verticality of the bus duct shall not exceed ± 5/1000.

After the installation of the busbar trunking is completed, all power supply terminals and branch leads are cut off and not connected to electrical equipment. At room temperature, a 1000V megohmmeter is used to measure the insulation resistance between phase and phase. The insulation resistance between phase and ground is ≥ 20M Ω. If the temperature is above 30 ° C and the relative humidity is above 90%, the insulation resistance is not less than 0.5M Ω. After baking, the insulation resistance can significantly increase. The insulation withstand voltage is 2000V per minute and there is no flashing phenomenon. Then it can be connected for power on trial operation.
