How to choose weak cable

According to the life plan selection specifications, weak electricity includes telephone lines, network lines, cable TV lines, audio lines, video lines, audio lines, and so on. Although the specifications are high or low, the weak electricity should be selected according to the owner's own life plan to decide whether to choose high-standard products.

TV line

At present, four layers of shielded coaxial cables are generally selected. The most important thing to choose TV lines is to see if the wiring layer is tight. The closer the shielding function is, the better the TV signal will be. The thickness of the copper wire can also be seen. The thicker it is, the better its anti-magnetic and anti-interference signals are.

Audio line

Commonly used in building materials supermarkets are 200-core and 300-core wires. In general, 200 cores can meet basic needs. If the sound effect is very high, such as the sound is very realistic, consider the 300-core audio cable.

cable

The five types of double shielded and unshielded six types of network cables are generally sold. The former is a 100 Mbps network speed. Even if there are multiple computers in the home, it can meet the basic needs and the shielding effect is better. The latter is Gigabit network speed, and the shielding effect is poor.

telephone line

There are 2 core and 4 core single-use telephone lines. The 2-core single-strand telephone line can meet the general needs, and the 4-core cable can meet the needs of installing two different number telephones in the home. And the 4-core single-strand telephone line has two lines for backup. If other lines are broken, the relative risk is small. Of course, the price difference between the two is about 1 yuan / meter.

Buy common sense

Wire specifications are high or low, but you should choose according to your own conditions, not the more expensive, but also consider the long-term. For a wire that is sufficient for 4 square millimeters, there is no need to buy a 6 or 10 square millimeter wire. However, products such as telephone lines and network cables, if you plan to live for a long time, can foresee future changes in life such as video calls and other factors, combined with cost budgets, to consider whether they are in place. If you only live temporarily, you can buy enough products, there is no need to buy advanced products.
