Precautions for installation of inflatable shaft

1. The copper sheath of the inflatable shaft can be used for grounding, and it is necessary to be grounded. 2. In the process of laying the device, the insulation of the inflatable shaft should be checked frequently, and the problem should be solved in time. 3. Understand the matching accessories of the inflatable shaft, as well as the device and application method of each accessory. 4. After the inflatable shaft is laid, if there is no center joint, you can directly make the terminal head. If there is a center joint, you should do the center joint first, otherwise it will increase the laborious work such as phase checking. 5. Understand the construction drawings and site conditions, and formulate specific construction plans. 6. In the process of laying the inflatable shaft, or after the installation is complete, it is necessary to strictly prevent the electric welding faucet wire from dragging or bumping on the inflatable shaft. 7. Fully understand the structure, function and characteristics of inflatable shafts, understand the types, specifications, varieties and customary places of inflatable shafts. 8. To be proficient in the installation of the inflatable shaft, the method, method and technology of the installation, understand the matters needing attention in the construction, such as the tortuous radius of the inflatable shaft, the placement of the laying, how to get in and out of the distribution box, cabinet, and how Take care to eliminate eddy currents.
