My friend's household appliances are all covered with yellow wax pipes. Don't use
your friend's home decoration to help. His home is just running water and electricity lines, and the decoration master has wrapped yellow wax pipes for his home. But when my home was renovated before, I clearly heard from the decoration master that it is no longer supported to use yellow wax pipes for wiring at home. I'm not sure, then I asked the master, and finally I made sure that my friend's house was really wrong!
First, let's give you a general knowledge about the yellow wax pipe:
Yellow wax pipe is a kind of threading pipe, which has good flexibility, elasticity and insulation, and is relatively temperature-resistant, so it is suitable for wiring insulation and mechanical protection of electrical appliances.
let's talk about the other side: why do we need to cover the wires when the circuit is reformed?
there are two reasons. one is to protect the wires. Second, it is easier to replace and maintain if there are problems in the future, because the wires can be extracted after being wrapped in hard pipes, which is more flexible.
Because of this, the yellow wax pipe is not recommended, because it can't be stretched after being buried in the cement wall, so it can't be directly pulled out to replace the wires.
but this is only for trunk lines, such as concrete walls and tops. In other places, yellow wax pipes are still used more.
what kind of conduit should I use?
pvc flame-retardant conduits are commonly used, and the depth of slotting is consistent, and 1mm is added to the original diameter. It is more durable, because it has insulation and flame retardancy, so even if there is any problem with the wires in the future, it will be protected by pipes. Moreover, it is quite expensive and easy to install.
after telling all this to his friends when he got home, he immediately asked the workers to rework and repave the trunk line, saying that he was afraid that there would be more trouble in the future!
