Wire specifications and their use occasions

Wire is an indispensable material in the process of home improvement. Although it is only a thin line, the role is very large. What is more, it is related to home security. The following Xiao Bian came to talk about some common sense about wires.

The classification and application of wires

The wire used in home improvement is generally a single-stranded copper wire, and its cross-sectional area mainly has three specifications, namely 4.0 mm2 , 2.5 mm2, and 1.5 mm2 . There are also 6.0 mm2 specifications, which are mainly used for entering the main trunk line. There is little or no use in home improvement, and they are generally not included in the scope of home-use circuit lines.

  

4.0 mm2 single-stranded copper core wire is used for circuit main lines and special lines for air conditioners, electric water heaters, etc., 2.5 mm2 single-core copper core wire receptacle and part branch wires, 1.5 mm2 single stranded copper core wire for lamps and switch wires The ground wire in the circuit generally uses 1.5 mm2 single-strand copper wire.

In addition, we must use telephone lines, television lines, network cables, and audio cables in our home improvement. These lines are all within the scope of a dedicated line. The specifications are relatively uniform, but there are some differences in quality. It is recommended that you choose better quality when you purchase. It is appropriate.

  

Second, wire threading considerations

Threading pipe and switch box must be selected for good quality, circuit and other basic projects are the top priority of home improvement, we must choose the best within the range of capabilities. Threaded pipe should use flame-retardant PVC pipe, smooth wall, high strength, and certificate of conformity. Can not choose three products. The PVC pipe is generally divided into 6 branches and 4 branches, and the economical situation allows the best use of 6 points. It should be noted that the 4 in charge can only wear 1.5 square lighting lines, and can only wear 3 at most.

  

Third, the line tube pre-installed

Line tube pre-installation is directly related to the status of the use of electrical appliances after the stay and the cost situation. In order to reduce these unnecessary troubles, to live in peace of mind, you have to be particularly concerned about these basic projects. Some workers are perfunctory and do not pay close attention, but in the future they will suffer. Some small details must be insisted on with the decoration workers insist, do not miss due to a lazy moment.

  

1, the wire embedded pipe, the slot does not need to cut too deep. If there is a leveling layer, the upper line of the line pipe needs to be flush with the leveling layer.

2. There must be a groove in the joint of the line pipe, so that the surface of the line pipe is flush with the ground; as far as possible, the line pipe should be constructed in parallel; as far as possible, the joints at the corner should be staggered.

3. The elbow on the wall of the line pipe must have an arc to facilitate threading.

4, TV background wall and other areas with frequent electricity to prepare a sufficient number of outlets, cable outlets to be ready.

5, located in the door hole of the threading pipe, pay attention to the late construction of the door sleeve, nails do not destroy the line tube.

6. The ceiling of the ceiling is connected with a plastic hose. The slot should not be cut too deep to prevent damage to the floor.

The above is all about the specifications of the wires and their respective applications. If you want to learn more about the home improvement circuit, please pay attention to this site's information channel.
