What is hydropower? Hydropower is what it does

Plumbers belong to the construction industry.

Plumbers are the total slag disturbances of plumbers (plumbers) and electricians, referred to as plumbers. Plumber is the construction worker who installs some simple circuits and waterways on the construction site, and there are two kinds of plumbers, divided into installation of plumbers and maintenance plumbers, and the installation of plumbers such as belt workers is mainly to do the installation of civil electrical pre-embedded water supply and drainage fire bridges, and also do decoration, such as home decoration. The maintenance plumber is the plumber and plumber hired by the hotel school property.

The former is more tiring, has low technical content, and is basically manual work. The latter is relatively relaxed, but it is also not very technical.

Plumber Job Responsibilities:

1. Responsible for normal water and electricity, and eliminate problems immediately.

2. Regularly copy water and electricity meters by household, so that they are accurate, report to the accounting office in time, and assist the accounting office to do a good job in the settlement of water and electricity bills of each household.

3. Rational use of water and electricity equipment, save materials, and take care of tools.

4. Pay attention to safety and work according to relevant operating procedures.

5. Frequently inspect and maintain water and electricity pipelines to prevent accidents and <> caused by aging lines and other reasons

1. It is forbidden to bury the wire directly into the plastering layer.

2. The distribution wire should be laid with PVC casing. There are generally two kinds of PVC pipes: 4 points and 6 points, the 4 points pipe can only wear the square millimeter of lighting wire, and a pipe can wear up to 3 wires. The 6 pipes can thread wires in square millimeters, 4 square millimeters, and up to 3 wires in one tube.

3. There should be no knots and kinks in the distribution wires in the pipe. When the PVC pipe is docked, it is necessary to use joints, and at the same time, it should be firmly bonded with glue. Moreover, the connection between the PVC pipe and the wire box must be covered with a special sleeve, and the PVC pipe box and wire box cannot be directly docked.

4. All distribution wires, including strong and weak wires: lighting wires, air conditioning wires, punch resistant wires, first-class lines, network cables, cable TV lines, audio cables, first-class lines, audio lines, etc. should be casing. The proper operating specification is to connect all the pipes before threading the wires.

At the same time, strong and weak electricity must never be worn in the same tube. The minimum distance between strong and weak electricity is 20 cm to avoid interference.

5. No exposed wires are allowed in the ceiling.

6. During the construction process, the construction personnel must distinguish the direction of the circuit in the house in strict accordance with the drawings, determine the installation position of the cassette on the wall, and make relevant preparations for the opening of the wiring slot. When opening the trunking, the depth is twice that of the conduit used, the trunking must be horizontal and vertical on the wall, and the height of the cassette should be consistent. In the wire threaded into the conduit, it is not allowed to have a joint between the two cassettes.

TV and ** line in the process of wiring resolutely can not have joints,And these two lines can not be worn together with other lines,Must be threaded separately,TV、** The distance between the two lines should be not less than 15 cm。 After threading, it is necessary to ensure that the wire is pulled freely.

7. After the wire is crossed, the wire joint of the power supply should be double-insulated with insulating tape and waterproof tape.

8. The wiring of the lighting should be based on the principle of "live wire into the switch, zero line into the lamp head".

9. The protective ground wire of the three-hole power socket should be laid separately, and can not be mixed with the neutral wire (zero wire), and the socket wiring should comply with the provisions of "left zero right fire, grounding on the top".

10. The entrance line should be made of copper core wire, and the cross-sectional area of ordinary houses should not be less than 10 square millimeters. Mid-range homes are 16 square millimeters and high-end homes are 25 square millimeters.

11. The branch circuit should be made of copper core wire, and the cross-section should not be less than square millimeters. The lighting circuit should be made of copper core wire, and the cross-section can be selected in square millimeters.

12. Copper core wires of square millimeters are used for the power socket circuit in the kitchen and bathroom.

13. The air conditioning circuit should choose 4 square millimeters copper core wire.
