Circuit modification in home improvement is very important. If there are problems in circuit reconstruction, it may bring potential safety hazards to the home. Specifically, the circuit transformation includes the transformation of strong and weak currents, and there are many issues when the circuit is modified. Particular attention is paid to the decoration owner, especially the purchase of wires, wire tubes and switches and sockets. Follow the small series together to understand the circuit modification precautions.
Here are some of the lessons learned from the transformation of strong and weak electricity and the purchase of switch sockets.
First, the telephone line and network cable should be designed rationally
If your home is connected to the Internet through a telephone line (such as ADSL), you must plan when you answer the phone line and network cable. Many people can't use the phone on the Internet at home, or some people can't use the home network cable. That's when the design is made wrong. There are some Raiders on the Internet, but people can't read it clearly. Now we can use the vernacular to everyone. Talk about how to take the phone and network cable.
1, the phone line of the total entrance hole is best left to the computer desk, the phone line from the bus out of the ADSL dedicated to the distribution box, and then from the junction box on the hole that says PHONE can take a After the phone is divided into a line and then access to the wall (there is a telephone line jack on the wall), divided into the telephone hole in other rooms.
2. The telephone line coming out of the above ADSL distribution box is directly plugged into the ADSL dedicated cat. The cable from the ADSL cat can be plugged directly into the computer. However, if you want to achieve access to the Internet in other rooms, then you have to put ADSL. The network cable from the cat is plugged into the router, and the line from the router is passed back to the wall (there is a network cable jack on the wall), and it is connected to other rooms. Pay attention to access to several different rooms. Leave several different network cable jacks.
The above are all about traditional methods. Not only are there more lines, but the cost of the project is not low. It is also easy to make mistakes. In fact, there is an even simpler method. That is to use a wireless solution. If you use a wireless solution, it should be the same as the above two points. Operation:
Wireless 1. The total entrance of the telephone line is preferably left at the computer desk. The telephone line comes out of the bus and is connected to the ADSL dedicated distribution box. Then the hole of the PHONE is written out from the distribution box and directly connected. Go to the parent machine of the wireless device (preferably a digital cordless phone), and then you need to use the phone in which rooms. You can use this machine with several handsets, and you can use it in any other room.
Wireless 2. The telephone line coming out of the above ADSL distribution box is directly plugged into the ADSL dedicated cat. The cable from the ADSL cat can be plugged directly into the computer, but if you want to achieve other rooms, you can also access the Internet. The network cable from the ADSL cat is plugged into the wireless router (also called AP, pay attention to the corresponding model of the machine according to the area of â€‹â€‹the home), and as long as your computer has a wireless internet (Wi-Fi) you can access the Internet in any room. , Nowadays, notebooks are equipped with wireless internet cards. Even if some computers do not have any connection, it is OK to buy a wireless network card with a USB jack (usually only a few dozens). Many people worry that the speed of wireless Internet connection will be slow. In fact, it does not exist, as long as the installation is correct, wireless LAN and wired LAN as fast.
Second, the choice of circuit reform tube
The wall of the wire must pass through the pipe. Generally, there are two kinds of metal pipes and PVC pipes:
Metal pipes are more expensive, but their anti-jamming performance is stronger than that of PVC pipes and they are not afraid of fire. In the future, the protection of electric wires will be stronger than that of PVC pipes (for example, the use of PVC pipes may inadvertently break into the wall when nailing).
PVC pipe is affordable, turning is easier than metal pipe, and insulation performance is good.
In fact, the general family choose PVC pipe is very good, but to choose a solid, simple method is to step on the foot, will not be stepped on is good. Finally reminded: No matter what type of pipe threader is used, the cable cannot have a connector in the pipe.

PE Plastic Rod, full name is Polyethylene Rod.
Physical properties: PE plastic Rod is the most simple structure of the macromolecular organic compounds, the world's most widely used polymer materials, composed of ethylene polymerization, depending on the density is divided into high density polyethylene Rod, medium density polyethylene and low density polyethylene.
(1) LDPE Rod
Low density polyethylene Rod (also known as high pressure polyethylene Rod)
(2) LLDPE Rod
Linear low density polyethylene
(3) MDPE Rod
Medium density polyethylene
(4) HDPE Rod
High density polyethylene (also known as low pressure polyethylene)
(5) UHMWPE RodUltra high molecular weight polyethylene
(6)Modified polyethylene Rod
Chlorinated polyethylene (CPE) and crosslinked polyethylene (PEX)
(7)Ethylene - ethylene copolymer
Ethylene/propylene copolymer (plastic), EVA, ethylene, ethylene butene copolymer - other olefins, such as octene POE, cyclic olefin copolymer, ethylene/unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH).
Polyethylene, which has a molecular weight of 3 million to 6 million, is known as UHMWPE.
Ultra high molecular weight polyethylene Rod is very strong and can be used for body armor.
