Meaning of sheath wire

1. Generally, when using wires, a layer of sheathed wire is installed outside, so that the wires can be directly buried inside the wall, with strong safety performance and fewer unnecessary and cumbersome procedures in the program. It is simple and has a beautiful appearance. In addition, sheathed wires are still used in some high-power household appliances, which can prevent life damage caused by leakage and have a certain protective effect on everyone's life safety.

Specification of sheathed wire

1. According to the material, the sheath wire is generally divided into two types: hard sheath wire and soft sheath wire; According to shape, sheathed wires can be divided into circular sheathed wires and flat sheathed wires; According to the core, sheathed wires can be divided into multi-core sheathed wires or single core sheathed wires.

There are four common specifications for sheathed wires, namely BLVV, BVVB, BVV, and BLVVB. The letters here have their respective meanings, with L representing aluminum core, V representing polyvinyl chloride insulation, and R representing soft.

Performance of sheathed wire

1. Strong tolerance performance. As it is a material installed on the surface of the wire that has a protective effect, its protective ability must be strong, so a more resistant material will be chosen to make the sheath wire. Moreover, mutual sheathing should be used in regions with different temperature differences, such as cold winters in northern Europe and hot weather in Africa, or temperatures in northern and southern China that differ by tens of degrees. Therefore, the temperature tolerance performance is good in order to play the role that the sheathing wire should play.

2. Environmentally friendly materials. Due to its unique material, most of the sheath wires on the market are made of environmentally friendly materials, which do not pollute the environment and pose no harm to everyone's health. This is also a major highlight of sheath wires.

3. Long service life. Due to many sheathed wires being buried in walls and difficult to replace, the service life of sheathed wires is generally long, which can reduce the inconvenience caused by aging of sheathed wires, which is also a major manifestation of their excellent performance.

4. Strong insulation performance. This is a basic function of sheathed wire. The sheathed wire is combined together through multi-core insulated wires, with strong insulation performance and can play a role in insulation protection, making it convenient for everyone to use.

5. Easy to use. The use of sheathed wires is very convenient, which can save everyone time installing electrical appliances and facilitate their use. It is both safe and convenient, and has a wide range of applications.

Selection method of sheath wire

1. Observe the appearance. The selection of sheathed wire can first start with its appearance. If the color of the sheathed wire is bright, the feel is good, and the appearance is soft, then the quality of the sheathed wire is relatively good. You can also use your nails to pinch the sheath wire. If there are no white marks left on the sheath wire, this type of sheath wire is a relatively qualified product.

2. Observe the cross-section. The insulation layer from the outer layer to the inner layer must maintain a uniform thickness. If some areas are thick and some areas are relatively thin, the thickness may vary and the use experience may be poor. Moreover, cracks and other issues may occur in the thin areas, which can pose a certain threat to everyone's safety and health.

3. Observe the conductor. The conductor is an important component of the sheathed wire and directly determines the quality of the sheathed wire. Firstly, everyone needs to check the flexibility of the conductor
