Strong electricity refers to the 220v voltage line, mainly lighting. Sockets. Air conditioners and other household electrical power lines, such as: electric water heaters, fuel dispensation devices, microwave ovens, electric ovens, dishwashers, washing machines, refrigerators, Yuba, TV audio and so on. According to the civil building code, the lighting line uses 1.5 square meters, the socket 2.5 squares, and the high-power air-conditioner 4 square line. Currently, most of the civil buildings in Shanghai are constructed in strict accordance with the standard. If there is no moving power box in the home improvement, there is no need to discard the original. Some of the wiring, all re-appropriate the wiring, in addition to a great waste of social resources, the slot in the floor, and even deep to 5 cm, which is the destruction of the building structure! Is it necessary? It is worth thinking deeply!
Weak electricity refers to the network, telephone and television lines, as well as the circuit of the district's anti-theft monitoring system. The strong and weak electricity must be worn separately and must not be worn by the same power! Cable and network signals are relatively fragile, and connectors should be minimized. Terminals must be inserted. Excessive exposure to copper will oxidize for a long time, resulting in poor contact and resistance. This will cause signal loss and instability, affecting the receiving effect of television (image jitter or weight Shadow) and computer's Internet speed (may be always broken). Home-installed network and cable must use high-quality wire and good contact pads, and you must not buy cheap wire!
When a cable company first opened a digital TV a few years ago, the construction of the door-to-door connection would be connected to the TV station from the main office of the corridor, one line at a time, that is, each TV would be connected to the corridor! The TV image is absolutely superb and the cable speed is excellent! Today's new homes have weak boxes, and the shortest path should be selected when re-wiring. The contact must be good when wiring! Otherwise, after finishing the floor boarding, I found that there was something wrong with the cable and the network. I regret it! Someone can only rearrange the open line.
