How to know what kind of wires you need in your home renovation is also a problem that confuses consumers. Insiders pointed out that before home improvement, the owner should understand the knowledge of some commonly-used wires, which is a great advantage for purchasing products.
What we usually talk about is the laying of plastic copper wire. There are 1.5 square meters, 2.5 square meters and 4 squares for the plastic copper wires currently on the market, and the basic level of 2.5 square feet and 4 square feet for home life is sufficient. In general, there are six or seven strong roads at home, including lighting lines, socket lines, kitchen socket lines, bathroom socket lines, air conditioning lines, and a spare line. In addition to the air conditioning line to use 4 square line, the other can choose 2.5 square, bathroom and kitchen can also use 4 square lines if there are many electrical appliances. In the market, there are many other grades of plastic copper wire, such as low-smoke, halogen-free and other grades. Home-made plastic copper wire can be used.
Weak electricity includes telephone lines, network cables, cable television lines, audio cables, video cables, and audio cables. The grades of products sold on the market are high or low, and some of them are quite different in price. You can decide whether to choose high-quality products according to your own life planning and economic conditions.
TV lines have common coaxial lines, two-layer shielded coaxial lines and four-layer shielded coaxial lines. Currently, four-layer shielded coaxial lines are generally selected.
The cable is divided into Super Category 5 cable and Category 6 cable. There are also shielded and non-shielded. Home appliances often use Super Category 5 double shielded cable. Even if there are multiple computers at home, it can meet basic needs and the shielding effect is also good.
The telephone line is divided into two cores and four cores, and is also shielded and unshielded. Under normal circumstances, the 2-core shielded telephone line can meet the general requirements, and the 4-core line can meet the needs of installing two different telephone numbers at home. And the 4-core single share telephone line has two lines ready for use, and other lines are broken.
According to industry insiders, after understanding these basic knowledge, it is also advisable for the workers to draw up a list before purchasing electric wires and go to the market for purchase according to this list. Because even if it is the same kind of wire, there are many different grades on the market, so it's hard to be dazzled.
