2022-01-14The structure of the wire and cable casing is similar to that of the rigid waterproof casing, except that it is combined with more rigid waterproof casings, so it is also called a rigid composite casing. There is also a baffle to prevent shock waves. For welding, it is generally necessary to install a resistance sheet, some are equipped with a ribbon cap, and some are equipped with a bell mouth to save money and trouble. This is determined by the user according to the actual use situation. If the electrical protective sleeve is set between 2 personal defense zones , Both sides of the electrical protective sleeve are provided with sealing ribs and baffles against shock waves.
Installation Notes:
1. It is intended to prepare for the installation. Before the formal installation of the casing, all aspects of the inspection work should be done to ensure that there are no problems before the next operation can be carried out. For example, each casing should be checked. Whether the water is unobstructed, and the quality of the casing body, try to avoid bending, or even if it is damaged. And the wall-penetrating casing manufacturer reminds you to carefully clean the threads and apply lubricating oil. And check and ensure that the corresponding parts of the casing remain unobstructed, etc.
2. Pay attention to the fixing work when lifting and ensure that the skipping rope must be checked first when lifting the casing. The manufacturer of the wall-penetrating casing emphasizes to ensure that there is enough fastening. If it is a casing with a relatively large diameter, it must be The public client should brush a rope so that it can play a more solid role. And the honest wall bushing manufacturer should also want a heald rope, which can reduce the effect of the casing swinging, and then the commander will tell the The driver gestures to signal the next move.
3. Pay attention to the operation details of the wellhead. The manufacturer of high-quality and reliable wall-penetrating casing reminds that at this time, it is still necessary to check the relevant tools first to ensure that all tools are flexible and easy to use. There is no problem with the quality. When it is necessary to take measures to ensure that no objects fall into the casing or the well, all the staff should cooperate with each other and focus on each operation to ensure and more efficient one-step delivery.
Wire and cable bushings are mainly produced in accordance with the standard 07FD02 Atlas. This product is mainly used to solve some underground projects that require pipelines to pass through walls, and there are strict waterproof requirements at the passage; some structures also require pipelines to pass through. It is designed and manufactured to pass through the wall, and at the same time, the pipeline cannot be stretched and displaced due to temperature changes or external forces, and it is not allowed to vibrate under the action of external factors. When the line or steel pipe passes through the middle of the electrical protective casing, The outer diameter of the pipe and the middle of the casing should be sealed with packing, which plays the role of water-proof, leak-proof and shock-absorbing.
