The application of wire and cable has brought us light and met the needs of our family's life, but in the installation, it is necessary to follow certain principles or standards to ensure that the wire can be used normally after installation or without too many problems in subsequent use.

Nowadays, most of the line installation is buried in the wall, that is, we often say the hidden line, the hidden line is safer, reliable and beautiful than the open line, so how long can the line be buried in the wall, if there is a problem how to replace it, Tianxing cable summarizes the following three points.

First, the line buried in the wall will not have a short circuit, this depends on the quality of the line you installed at that time, this can not be found accurately, the key to see when you were threading the line is wearing live line, or wear dead line, if it is wearing live line, then find the short circuit of the group of line, pull out and replace it, if the dead line is no way. Therefore, the line of the buried wall should be used as far as possible after quality inspection, and the probability of failure is relatively small.

Second, the wire buried in the wall is protected by PVC wire pipe, and it is really not necessary to use the wire pipe with the sheath line, but the sheath line will be corroded in the wall, the service life is not as long as the wire pipe and the risk is relatively large, and the maintenance is not convenient, as far as possible, the wire pipe protection.

The wire is buried in the wall, must be in accordance with the standard way of operation, according to the construction requirements of the electrical line, any wire is not directly buried in the wall or underground without the sleeve, which is mainly to eliminate safety hazards and facilitate future inspection and repair.

Directly buried in the wall or underground wire in the case of high current through the heat, because there is no space for heat dissipation, will accelerate the aging of the wire insulation layer deterioration, from the occurrence of leakage, electric shock accidents. In addition, due to the reason of thermal expansion and contraction, the wall (ground) may have cracks and deformation, which may cause the wires inside the wall (below the ground) to break, causing line failure, or leakage, electric shock accidents.

Third, the life of the home wire directly buried in the wall is generally about 20 years, if the home does not use high-power electrical wires can be used for 50 to 60 years, it must be under the premise of standard wires, and there is according to standard construction.

In home decoration, line installation is an important item, we should do a good job of line installation before decoration, pay attention to some line installation skills, if necessary, please ask the relevant technical electrician for line installation.

Qingdao Tianxing Cable Co., Ltd. focuses on the production of customized wire and cable manufacturers, main: fire wire and cable, power cable, control cable and other products, exported to more than 40 countries and regions around the world, the annual production capacity of 1 billion yuan. 6000 square meters of storage, standing hundreds of millions of inventory, order demand for rapid distribution and delivery, large prices more favorable.
