Why do we separate strong and weak electricity during decoration?

In circuit decoration, strong electricity and weak electricity must be separated according to regulations. What are weak electricity wires? How to distinguish them during decoration? Let's follow the Handan Decoration Network to learn about what weak electricity wires are in home decoration and why strong electricity and weak electricity are To be separated.

Why do we need to separate strong and weak electricity in home decoration?

According to relevant regulations: wires of different voltages or different watt-hour meters must not be worn in the same pipe.

Strong and weak currents are laid in a steel wire tube to avoid strong current interference with weak currents.SYWV Strong and weak current wires must be separated. This is regulated and cannot be run in the same wire tube.

What are the weak wires for home decoration?

1. Telephone line

In an era when mobile phones were not widely circulated, the telephone was a communication tool commonly used by people for long-distance communication. To ensure that your home phone can make normal calls,AVVR cable you must install a phone line at home. The telephone line is a type of weak wire. Telephone lines are generally made of copper core wires. The number of copper cores represents the number of telephone extensions that can be connected. The commonly used core numbers are two-core and four-core. The number of telephone lines commonly used in ordinary households is two cores, and a few households use four-core telephone lines.

2.TV cable

TV cables are lines used to transmit TV signals and are also weak wires. TV cables can be divided into cable TV coaxial cables and digital TV coaxial cables. CATV coaxial cables use double shielding to transmit TV signals, ul 758 cable while digital TV coaxial cables use four shielded cables to transmit TV signals. . Generally speaking, the greater the number of shielded cables, the smaller the loss when transmitting TV signals, and the stronger the anti-interference function.

3.Network cable

Network cable is also a kind of weak wire, which can be mainly divided into three types: twisted pair, coaxial cable, and optical cable. Optical cable is the most advanced type of network cable. This network cable has the strongest anti-interference and the fastest network signal speed. Capacity is also the largest; while coaxial cable and twisted pair have slightly worse performance.

4.Audio and video cable

Audio-visual cables are lines used to transmit music signals and video signals. They generally include three types: audio cables, audio cables and audio and video cables. In an era when computers were not yet popular, audio-visual equipment was a common device used by people to listen to music and watch videos. The normal use of audio and video equipment is inseparable from the audio and video cable. Only if the audio-visual cable is installed at home can the audio-visual equipment be used normally.
