The renovation of hydropower is a relatively professional part, and it is also the focus of the renovation. The transformation of the circuit must be strictly in accordance with the norms, otherwise it may not only cause inconvenience to life, but also seriously threaten the personal safety of the family. Then, how does the transformation of the circuit be called the norm? First, the circuit transformation can not be sloppy wire is very important In home decoration, it is necessary to involve strong electricity (lighting, electrical appliances) and weak electricity (television, telephone, audio, network, etc.) circuit lines buried dark lines, wire is very important; Second, the wire specifications have to choose appropriate Selection of wire specifications: In home decoration, according to national regulations, lighting, switches, sockets use 2.5 square meters of wire, air conditioning use 4 square wires, and water heaters use 6 square wires. Third, the circuit installation method costs more than the same At present, there are many ways to install electricity, some are 12 yuan/square, some are 15 yuan/square, and practices are different, and the cost of work is also different. 1. Functional approach: There is no need to divide many groups. As long as it can achieve the purpose of using electricity, a three-bedroom, two-room house is divided into four groups. 2, grouping practice: grouping is the first space must be grouped separately, each space air conditioning but also separate grouping, a three-bedroom and two-room need room 3 groups, living room 1 group, restaurant 1 group, 2 bathroom 2 group , Kitchen 1, air conditioning in three rooms to 3 groups, living room air conditioning in a group, a total of 12 groups of lines, each group needs a separate air-to-air control. If you use ordinary PVC pipe threading, it is 12 yuan / square labor costs. The labor cost for threading with a cold bend is 15 yuan/square, because each bend requires a bender to make an elbow, which is time consuming and expensive. Strong and weak electricity slot layout, to add 3 yuan, is 18 yuan / square, plainly is to increase the slotted money. 3, the national standard's practice will be 22 yuan, completely open horizontal slot, only open vertical slot. Fourth, the circuit construction can not be regulated in accordance with the steps The principle of hydropower construction is "walking the roof and the roof can't go. Consider taking the wall and the wall can't go before considering the ground." The top line is inside the ceiling or gypsum line. Even if there is a fault, maintenance is convenient. The loss is not great. If all is gone, the overhaul will guide the lift of the floor. The ground is a concrete structure. To bury the line, it will inevitably hurt the concrete layer and even reinforce the steel. 1, according to the requirements of positioning First of all, according to your use of electricity for circuit positioning, for example, where to switch, where to socket, where to light and other electrical will be based on your requirements for positioning. 2, slotted to regulate After the positioning is completed, the electrician opens the wiring trough according to the positioning and circuit direction. The wiring trough is very particular and should be horizontal and vertical. However, the normative practice does not allow the horizontal trough to be opened because it will affect the bearing capacity of the wall. 3, buried wiring commonly used pipe buried The wiring is generally buried in a buried manner. There are two types of wire tube: cold bend tube and PVC tube. The cold bend tube can be bent without breaking. It is the best choice for wiring because it has a radian, and the wire can be replaced at any time without opening the wall. 4, bend arc The elbow should use the elbow tool. The radian should be 10 times the diameter of the pipe, so that the thread can be removed or disconnected. 5, circuit wiring 17 principles (1) The distance between strong and weak electricity should be in the range of 30-50 cm, because strong electricity can interfere with your TV and telephone; (2) Strong and weak electricity can't be put in the same pipe. (3) The total cross-sectional area of ​​the conductor in the pipe shall be less than 40% of the cross-sectional area of ​​the protective pipe, for example, up to four 2.5 square lines in the 20 pipe; (4) As far as possible, the long-distance line pipe should use the whole pipe; (5) If the line pipe needs to be connected, use the connector, the connector and the pipe must be glued well; (6) If the cable pipe is on the ground, it should be immediately protected to prevent cracking and affect the subsequent maintenance; (7) When the wiring length exceeds 15 meters or there are 3 bends in the middle, a junction box shall be installed in the middle, because when the wires are dismantled, they are too long or bent, and the wires cannot pass through the threading tubes; (8) Under normal circumstances, the wiring line should be more than 40 cm away from the heating and gas pipelines; (9) Under normal circumstances, the air conditioning socket is installed more than 2 meters away from the rehabilitated area; (10) Under the premise of no special requirements, the socket installation shall be 30cm above the ground; (11) switch, socket face the panel, should be the left side of the zero line, the right side of the fire line; (12) In home decoration, the wires can only be connected in parallel. It is definitely not easy for us to pick them up. (13) Pressing at the joints must be firm and firm; (14) A good line should be immediately wrapped with insulating tape; (15) During the renovation process, if the colors of the fire line, neutral line, and ground line are determined, the color cannot be mixed at any time; (16) The lighting, sockets, air conditioners, and water heaters in different areas of the home must be separately grouped and routed; once any part needs to be turned off for maintenance, it will not affect the normal use of other electrical appliances; (17) It is very important that after the circuit is completed, the constructor must give you a circuit layout plan. Once it is overhauled or wall repaired or nailed on the wall, it will prevent the cable from being damaged.
