The installation of hydroelectric power was a complex but important project during the household assembly. In the process of retrofitting water and electricity, particular attention is paid to the fact that all main and auxiliary materials should be certified by the state and operate in strict compliance with the construction regulations. And the next thing you know, you're gonna come by and give the internet a brief description of 10 hydroelectric installations。
1. Electrical (powerful, weak) and drainage design designs are required prior to the installation of utilities。
It is strictly forbidden to place the steering line in the walls, on the floor, under the floor or on the ceiling without any protection。
3. Different voltages, different circuits, and lines of different signals are strictly prohibited in the same penetrator。
4. The installation of lamps shall take place after the painting has been completed. The installation of lamps on the brick mix, the use of weeds and the application of hooks, bolts or swelling bolts are strictly prohibited. The bolts (or bolts) of fixed lamps shall not be less than two. Lights may not be installed on flammable components。
5. There are two types of protection for the electricity system: on-site protection and zero protection, which are generally currently being applied in our country. Attention is drawn to the fact that in the same system, it is strictly prohibited to use both forms of protection, which would otherwise cause security incidents。
6. It is prohibited to connect the conductor in a penetrating tube, i. E. When the length of the lead is not long enough, the connection to the lead line shall not be in the penetrator and shall normally be connected in a switch, plug, headbox, etc。
7. Pp-r pipes, copper tubes, etc. May be used for water supply。
8- the water piping shall be carefully checked for all connected areas to be fitted closely, securely and in the right direction, then subjected to hydraulic pressure tests and water testing for some time before burial。
9. Horizontal pipes for drainage should have a certain gradient and should be tightly connected to the vent to ensure no leakage. The length of the stand and the suspension card of the fixed pipe is reasonable and solid。
10. Installation of sanitary devices should be accurate, supported, mounted and solid. The leakage should be installed at the lowest point on the ground and dented into the ground at 5 mm. Pepsi are sealed with oil sludge or silicone connected to the ground or pipe and are inappropriate for the use of cement, which swells and causes damage to the bottom of the person。
Water and electricity installation codes need to be kept in mind to be safe and comfortable
