How much does it generally cost to transform hydropower in Shenzhen? What are the precautions?

Three bedrooms, two living rooms, one kitchen and two bathrooms, with a building area of 90 square meters and an indoor area of 76 square meters. The budget of the decoration company is as follows: 1. High voltage: 2.5-4.0 High voltage: 33 yuan/m * 123m=40592. Weak current: network cable, TV and telephone: 37 yuan /m*48m= 17763. Water reform: cold water 4 points: 80 yuan/. 22m=2 156 air-conditioning sewage: 50 yuan/m *4m=200 sewage drainage 4 inch pipe: 172 yuan/m *2.5m=430 sewage drainage 2 inch pipe: 98 yuan/m *4.7m=46 14. High voltage transmission line 2.5 strong wire: 65433. Only *28 PCs =280 concrete bottom box installation: 65,438+08 yuan/only * 65,438+05pcs = 270 total * * 65,438+04, 500 yuan (1) water and electricity engineering costs account for 20% of the family decoration. Check whether there is an inappropriate route. It is very important to avoid bending as directly as possible in hydropower transformation. Whether there is an intermediate junction box in the bending place will facilitate maintenance and meet the needs of life. (II) Stability of hydropower In the renovation of hydropower, the wiring of the circuit must be protected by PVC pipes, and the strong and weak current should be kept at a certain distance to avoid the influence of strong current on weak current signals. Indoor wiring, telephone, TV and network cable must not be connected in series, so as to prevent interference between signals. This is very heavy, otherwise there will be problems in the future, and even the problems will not be easy to find.
