In home decoration, water and electricity decoration is the most important, especially the electrical part, because it involves the safety of electricity use. If there is a problem with the electrical decoration, it may directly affect the safety of the family and the consequences are quite serious. Therefore, whether it is the wiring, connection, or purchase of PE Cable, there must be reasonable planning and prior understanding.
At present, there are two types of wires for household use on the market, single-core and multi-core. Single-core wire means that the internal conductor is a relatively thick copper core, and the multi-core wire is twisted together by multiple thin copper cores. In comparison, single-core wires have higher hardness, and multi-core wires are softer, and their advantages and disadvantages are also obvious. You need to choose according to your own needs.
220V alternating current is used in the family, whether it is a single-core wire or a multi-core cable, as long as the qualified product is suitable for working under such conditions, the performance of the single-core wire will be more stable and the surface area It is small, not easy to be oxidized, and has higher mechanical strength. Multi-core cables are more flexible and easier to pull and bend, which is more convenient in the installation process, and it is not easy to damage the wires. In terms of price, the price of a single core is slightly cheaper, so when considering whether to use a single core or a multi-core wire, you need to choose according to your own needs and the characteristics of the wire.
In addition, when choosingSingle core cable, the most important thing is to see whether it meets the national standard. It cannot be a shoddy non-standard product. There are manufacturers, specifications, wire diameters, certification marks, and anti-counterfeiting queries on the wires. As for the amount of wire to choose at home, it should be determined according to the number and requirements of electrical appliances in the home. Generally speaking, the light wire uses 1.5 square wire, the socket uses 2.5 square wire. There are more electrical appliances in the kitchen and bathroom, and the power is large. It is best to use 4 square wires, vertical air conditioners use 4 square wires, and central air conditioners use 6 square line.
