The first step in the renovation of apartments is the construction of hydropower. There are many points for hydropower construction. Even if you are a small white decoration, it doesn't matter. Today we will come and learn some small details about hydropower installation. If you learn more, you will find many small details that are easy to overlook. The processing of these small details directly affects the subsequent use. What should we pay attention to in the construction of hydropower? Let's take a look. First, the circuit installation precautions 1, the wire connector can only be in the distribution box, socket, lamp holder, etc. can be opened and maintained in the place, do not have a connector in the threading pipe, afraid that the joints are loose after a long time, if not a joint is not, it is best to weld. There are two points to note: First, take a few lines in each pipe, because the general engineering fee is calculated according to the pipe, the current diameter of 20 commonly used pipe, if you go over five computer lines should take 4-5 The second is the use of materials to be agreed in advance. Forgot to explain: 2.5A per square is based on the value of the safe mode of the machine room to ensure that the wire will not heat, according to the electrical manual value should be 4A per square, in addition, the wire also allows Short-term overloaded use, in general, the cable should be changed within 15-30 years of use, because the aging of the skin will cause leakage, the aging of the skin will be related to the degree of wire heating, the use of the environment. 2, the wire does not need to change to see the electricity, generally each air conditioning and the kitchen's wires are independent walk, the lights and sockets in each room is divided into sections, open the distribution box and look at it will be clear Adding the power of appliances that may be used at the same time, divided by 220, to calculate the current required by the appliance, the wire current is calculated to be 2.5A per square, and the commonly used 2.5mm2 wire can go 6A, 4mm2 wire Can take 10A, (5 amps per kW; 2.5 amps can manage 16 amps, 4.0 amps can manage 20 amps) The number of electric currents allowed to flow through is greater than the number of electric currents required for the electric appliances used at the same time; (Home is the best choice Copper core wire, if only some simple household appliances generally choose 2.5mm copper wire, lighting is best to use 1.5mm or 1.0mm copper wire.If the home has air conditioning and other power home appliances recommended 4.0 The main line of mm, the use of 2.5mm copper core wire) 3, buy a wire to pay attention to whether the 3c certification, pay attention to the same length of wire, heavy weight is good; 4. The socket line and lighting line should be tapped under different switches (loops), and do not go in the same pipe, that is, different switches should take different lines: lighting goes one circuit, and the outlet goes one circuit, I recommend to use air-conditioning This part of the electricity also has to go through a loop. With these three loops, basically a room of one hundred square meters is basically enough. If it is a villa, lighting and sockets may be divided into two loops. The main reason for this is that the power consumption of air-conditioners is relatively high. Therefore, it is necessary to set up a circuit for the air-conditioning electricity bills. What are the benefits? When you're on the trip, you won't jump all over the socket. Sometimes you may be watching TV. Sometimes you may be using a video recorder. Sometimes the air conditioning affects you this period, so the air conditioner is the best one. With this one, it is not enough to reserve two more in the distribution box, leaving two more switches. It is recommended to leave two switches on the socket. Once there is water or a fire in the house, the power can be turned off or tripped inside the room. If there is leakage, you can also trip. The distribution box is usually made of iron. The distribution box must also have a ground protection. The distribution box may sometimes have a closed circuit trip in the room. Open the distribution box and close the gate. This time The distribution box is a tin box, so pay special attention to the ground wire. In the future, when you check it, take a look and try it out. 5. The switch of the whole house should be basically in the same horizontal position. The socket is 30 centimeters away from the ground, and the switch should be 140 centimeters away from the ground. Special sockets such as air conditioners, refrigerators and special requirements are exceptions. 6. The colors of residential fire lines, neutral lines and ground lines in circuit reconstruction must be unified; 7, socket line (including air-conditioned refrigerator) is best to use three lines more than 4.0 shares, lighting line with two lines more than 2.5 shares on it. And air conditioning line to go green, regardless of a few air-conditioning, it is best to use the 4.0 line. Lighting and air conditioning sockets do not have leakage switch; socket right hole is connected to the fire wire; 8, weak wire (220V) can be worn in a tube, as long as the cross-sectional area of ​​the line does not exceed 40% of the cross-sectional area of ​​the tube, strong wire the same reason. Strong electricity (220V) and weak electricity (television, telephone, network, etc.) cannot walk the same pipe. The price of telephone lines and network lines is similar. It is recommended to use network cables instead of telephone lines. In the future, your flexibility will be much greater. Turn the corner of the line and add the elbow; do not disconnect the connector at the middle of the pipe (no joint). Circuit modifications must have circuit diagrams (regardless of who draws) and must be saved to permanent (for overhaul); Second, water installation precautions 1, waterproof construction should use waterproof coating 2. The waterproof project should be done after the concealed project construction is completed and accepted 3, After the completion of waterproof construction to do two water storage test 4, the bathroom waterproof layer should not be less than 1.8 meters 5, floor drain, Yin Yang angle, pipelines and other places to do more waterproof 6, floor drain to use deodorant floor drain 7, hot and cold water left hot right cold 8, try not to walk from the ground 9, cold water pipe in the wall should have a protective layer of 1CM, hot water pipe is 1.5CM, so the slot to open deep 10, PPR pipe is installed to consider the thickness of the tiles, so that the pipe will not be exposed 11, only a few minutes to cook, wash vegetables for a long time, bucket must buy big 12, leading and counter basin to support, can not be installed on the up 13, toilet installation can not use cement, use silicone 14, toilets, taps should be carefully protected after installation 15, to consider the toilet pit when buying a toilet Hydropower installation of hydropower and hydropower Escutcheon lever lock door handle,door hardware,door lock hardware Wenzhou Shenghong Metal Products Co.,Ltd , https://www.shenghonglock.com
