When planning for wire installation, it's essential to choose premium threading pipes that ensure safety and efficiency. Opt for durable materials like PVC or PE threading pipes, which are cost-effective, flexible, and provide superior insulation. For household use, a PVC or PE threading pipe is a superb choice. To test durability, simply step on it — if it withstands the pressure, it's ideal. A crucial note: regardless of the pipe type, ensure there are no joints within the tube to maintain integrity.
When approaching circuit transformation, it's critical to avoid what is known as a 'dead line.' Despite superior circuit quality, future faults may necessitate line replacement. Ensuring the wires in the buried wall can be easily withdrawn and replaced is paramount. Thus, during electrical restructuring, it's vital to preemptively avoid creating unreplaceable 'dead lines':
1. Undoubtedly, the top priority is to utilize threading pipes when embedding wires.
2. Circuit wiring should adhere to the principle of the 'shortest distance between two endpoints' to prevent unnecessary loops. Such loops not only cause 'dead lines' but also escalate the investment required for electrical modifications.
3. Avoid overloading a threading tube with wires. After threading, ensure you can effortlessly pull the wires to confirm ease of future access.
4. If a wire has connectors, position them at the junction within the cassette buckle panel for easy future access and maintenance.
5. For pipes with a diameter of less than 25, use a pipe bender to form bends in PVC wire pipes. Refrain from adding elbow bends or right-angle bends, as they frequently result in 'dead lines' which are difficult to manage.
