When embedding wires in walls, it is imperative to use a threaded pipe. Typically, options like PVC wire pipe or PE wire pipe are favored for their affordability, flexibility, and excellent insulation properties. For most households, these pipes are exceptionally suitable. To ensure their strength, a simple tactic is to step on them; a durable pipe will withstand being stepped on without damage. A crucial tip: regardless of the type of threading tube used, ensure there are no wire joints within the tube to guarantee seamless performance.
In circuit transformations, it's essential to avoid creating 'dead lines.' No matter how superior the circuit quality, future faults may necessitate line replacements. Being able to easily extract and replace wires buried in walls is crucial. Thus, during electrical transformation, it is paramount to prevent scenarios where lines cannot be pulled out later, creating a 'dead line':
1. Undoubtedly, the foundational step is using a threading tube to embed the wire efficiently.
2. Circuit wiring should prioritize the 'shortest distance between the two line ends.' Avoid unnecessary winding, which not only risks creating dead lines but also escalates electrical renovation costs.
3. Avoid overcrowding a threading tube with too many lines. Ensure to pull the wire after threading to check for easy maneuverability.
4. If there is a connector in the line, it should always be located at the junction of the cassette buckle panel for convenient future replacement and maintenance.
5. For pipe diameters less than 25, utilize a pipe bender for bending PVC wire pipes. Avoid adding elbow bends, as right-angle bends often lead to dead lines, challenging the smooth flow and maintenance of the wire.
