Hydropower engineering is a very important part of home renovation. The necessary factor for the quality assurance of hydropower projects is that the quality of materials must be passed.

Generally speaking, if the semi-package is repaired, the wires, waterproofing and other materials are purchased by the foreman or the decoration company, but as the owner, at least you must know how to judge the quality of the materials. In addition to wires, decoration and electricity-related need to purchase air switches, circuit breakers, strong current boxes, switch sockets, ceiling lights, etc. Under the same brand model, the soft wire is twice that of the hard wire....

There are a few key factors to consider when considering whether or not you need to replace a 20-year-old wire. First and foremost, the age of the wire is an important consideration. Generally speaking, the lifespan of wires is around 25-30 years, and if your wires have been used for 20 years, then they may be close to or have exceeded their expected lifespan.

In addition, if a wire has failed or been damaged in the past 20 years, the need to replace the wire is even greater.

Therefore, if the length of the wires that need to be replaced in your house is about 100 meters, then you may need to expect to spend around 1000-3000 yuan.
