It is not only the quality of the telephone line that must be guaranteed. In the selection of switches and sockets, it is better to choose brand products or products with safety certification marks, and they should be purchased in large building materials stores. Do not try to buy in some hardware stores. There are no manufacturers or products with no certification mark to avoid the risk of counterfeit products. In wet environments such as bathrooms, special moisture-proof sockets must be used. Electric appliances such as air conditioners with large power consumption must be routed separately and use special sockets.

In the process of new house decoration, many people often pay attention to the quality and safety performance of carpentry and tile work, ignoring the circuit installation. As everyone knows, the safety performance of these concealed projects is even more important. Once rework is done, it makes everyone feel uncomfortable and does not say anything about it. The engineering movements are large, time-consuming, labor-intensive, and costly.
Mr. Zhao, who had just bought a house, had moved into his new home for a while, but the phone at home suddenly took off. He called on the phone and made loud noises that made it unbearable. Originally thought to be a problem with telecommunications here, but the people in the telecommunications sector came to a test. The phone line that had been buried under the floor tiles had problems. To fix it, you had to use a floor tile. Mr. Zhao was afraid to think of such a big project. In the end, he could only give up the telephone line.
Audiovisual room line must be professionally designed
Prevention: pipeline drawings to keep
At present, in home renovations, water pipes, wires, telephone lines, cable TV lines, etc. are generally not buried under the floor, they are buried in walls, covered with cement, and then surface decoration. This totally enclosed method has caused a lot of hidden dangers and has also brought great obstacles to the maintenance of pipelines in the future.
In fact, even in the commodity housing building books, the introduction of similar concealed projects such as electrical lines is mostly scarce. The owners cannot obtain a complete diagram of the electric circuit when purchasing a house, and they do not know the wiring of the house during the renovation process. Situation, the knowledge of safe power and wiring in the decoration process can be said to be blank. Therefore, keeping a complete pipeline trend drawing is a prerequisite for avoiding problems and solving problems in the future, otherwise it is impossible to start.
At the same time, it must be noted that construction personnel should hold electricians issued by the relevant state departments and prevent the occurrence of unlicensed construction.
Material: It is best to use copper wire
Due to the design reason, at present, most of the houses only have one telephone line entrance reserved. If they want to apply for the second phone, they will be rejected by the telephone exchange on the ground of being unable to pull the cable. Therefore, only the original one can be rejected. Make a fuss on the telephone line, sharing a line in each room? Therefore, the quality of the telephone line must be guaranteed, and the buried telephone line should be provided with a protective sleeve. Otherwise, once it is damaged, it will take a lot of time to repair it. If you want to use an ISDN home, it is better to bury the ISDN line and fit the corresponding wide interface when you want to decorate it so that you can connect a dedicated telephone or use an ISDN adapter to access the Internet.
It is not only the quality of the telephone line that must be guaranteed. In the selection of switches and sockets, it is better to choose brand products or products with safety certification marks, and they should be purchased in large building materials stores. Do not try to buy in some hardware stores. There are no manufacturers or products with no certification mark to avoid the risk of counterfeit products. In wet environments such as bathrooms, special moisture-proof sockets must be used. Electric appliances such as air conditioners with large power consumption must be routed separately and use special sockets.
In home renovations, copper wires are preferable because they have better electrical conductivity and higher safety. The plastic pipe buried in the wall is also best to use rigid PVC pipe.
Construction: Pay attention to floor wiring
In the construction of the wiring, if the ground is floored, whether composite or solid wood (bamboo), experts suggest that citizens should put the wire as far as possible on the wall foot behind the skirting board, only in the wall plug, door or wall, etc. A small pipe is buried behind the skirting board. There can be no dead curve in the middle of the line tube. Leave the lead wire in the tube. Wait until the floor is finished but the skirting board is not yet installed. After installing the skirting board, it will not see any traces of the traces, it is very beautiful.
Since the flooring is laid in the final stage of the renovation work, when the flooring is laid, it can be effectively prevented from causing accidental damage to the wire during the long construction period. When the public wants to change lanes or add lines, it is very convenient to remove the skirting boards for construction. Because the line pipe does not go under the floor, it is not necessary to cut off the wooden keel underneath the solid wood (bamboo) floor (except when the line pipe and the wooden keel move toward the same direction), thereby improving the construction quality and reducing or even eliminating the stepping of the solid wood (bamboo) floor. The possibility of ringing.
If the citizens' new homes are paved with floor tiles, it is best to route the pipes. The role of the line tube is not only to protect the wire, it also has the function to facilitate the replacement of the wire.
Renovation: Replace the aluminum wire in the old house decoration
Experts said that if the public renovated the old house, the original aluminum wire must be replaced with copper wire. Because the aluminum wire is easily oxidized, its connector can easily catch fire. According to the survey, the incidence of electrical fires using aluminum wire is several dozen times that of copper wires. If only the switch and outlet are changed, it will bury potential safety hazards for the residents in the future.
In addition, a sufficient number of loops is essential for modern home life. With enough loops, a short circuit or other problem on one line will not affect the normal operation of other circuits. According to the area of ​​use, lighting circuit can choose two or three way, power socket three to four way, kitchen and bathroom go all the way, air-conditioning circuit two to three roads, one air-conditioning loop with up to two air conditioners.
Good to know: wiring
In order to be beautiful and easy to check and replace, slotting and dark pipe laying are generally used. During the wiring process, the principle of "fire line into switch, zero line into the lamp head" should be followed.
Leakage Protection
In addition to air conditioning power outlets, other power outlet circuits should be equipped with leakage protection devices.
Number of outlets
The number and variety of electrical appliances in each household is increasing, and many households use pull-out socket boards to meet their electricity needs while ignoring security factors. Due to the accidental electrical shock and electrical fire accidents often caused by the temporary line in the room, it is important to remember that the socket board can only be used temporarily.
When decorating, you should consider increasing the number of fixed sockets in the wall. It is recommended to refer to the Hong Kong standard: 4 bedrooms per room, a group of 2.5 square meters in the living room, and a kitchen of 1.2 square meters.
Socket type
In order to prevent children from getting an electric shock, a safety socket with a safety cover should be used; refrigerators and air conditioners should use separate, protective grounded three-eye sockets; the bathroom should be damp, and ordinary outlets should not be installed but splash-proof sockets should be used.
Installation position
General switch from the ground 1.2-1.4 meters, horizontal distance from the door frame 0.15-0.2 meters, the same indoor switch height should be the same; wall mounted socket not less than 1.8 meters away from the ground, concealed socket distance 0.3 meters is appropriate. Of course, the specific installation location has to be determined by the placement of furniture and electrical appliances.
Installation method
Single-phase two-eye socket wiring requirements are: "zero left and right fire" when horizontally arranged, and "zero under fired" when vertically arranged; the zero line of three-eye socket and protective grounding wire must not be wrongly connected.
