Fu Li Da Ge, a teacher who has been engaged in water and electricity for 28 years: This is the standard water and electricity technology! Let's have a look!

Is water and electricity decoration going to the top or the ground? How many owners in the decoration because do not understand, because tangled, let the decoration company to decide, but how many decoration company is really for the owners? How to do well, how to do, how to make money. All kinds of arbitrary, disorderly, and finally also plausible. This is not, today Xiaobian brings the trend and layout of hydropower in the eyes of national standard electricians. You can compare the differences.

National standard teacher Fu: no matter whether you are home decoration or tooling, the principle of hydropower transformation is to take the top instead of the ground. If the top can't go, then consider taking the wall, and finally consider taking the ground

The reasons are as follows:

1. Water and electricity go to the top:

① First, some lines and pipes on the top can be directly in the ceiling, and the floor height will not be reduced on the basis of the ceiling;

② If there is a problem in the later stage, the maintenance is very convenient, and the loss is also reduced to the minimum as far as possible

2. Water, electricity and land

① The ground is a concrete structure, to bury the pipe, will inevitably damage the concrete layer, or even steel.

② Once there is water leakage in the later stage, you can't find it at the first time. After you find it, it will affect the neighbors downstairs. The maintenance cost is not ordinary.

What are the detailed principles of hydropower transformation?

1. Positioning: before decoration, it is necessary to communicate with the owners about the positioning of home appliances and other electricity, such as where to use switches and sockets, where to use lamps, where to put what kind of appliances, where to use water, etc., which all need further communication and positioning.

2. Slotting: after the positioning of the water circuit in the whole house, the electrician will decide whether to slott according to the positioning and the direction of the circuit. If slotting, remember that only vertical slots can be opened, not horizontal slots, which will greatly reduce the bearing capacity of the wall.

3. Wiring: we usually use the way of buried wiring, but there are mainly two kinds of wiring pipes, one is PVC pipe, the other is cold bend pipe. The cold bend pipe is used for the purpose of bending, which is the best choice for hydropower transformation.

Wiring principle

(1) When we arrange the strong and weak current, we must remember not to be adjacent to each other, and the distance between them should be 30-50cm, otherwise, there will be some interference when you use them later.

(2) Remember not to use the same pipe for strong and weak current.

(3) The cross-section area of the conductor passing through the pipe must be less than 40% of the cross-section area of the protective pipe. For example, if the inner diameter of a pipe is 20, the pipe can pass through at most four 2.5 square wires.

(4) Strong and weak in the cross wiring, we must use tin foil, which can play a role in shielding the signal.

(5) Long distance pipes should not be spliced. It's better to use the whole pipe. If you really want to splice, you must glue the joint and pipe well

(6) If the wiring material in the home is too long, there will be bending in the middle, then a junction box should be installed in the bending place, otherwise when disassembling the wire, if it is too long, the wire will not pass through the threading pipe;

(7) There must be a distance between the laying of electric wires and the laying of gas pipes, at least 40 cm.

(8) If there is no special case, the socket of air conditioner should be more than 2 meters.

(9) The switch socket in the home must follow the principle of left zero and right fire;

(10) The lighting, socket, air conditioner, water heater and other circuits in different areas of the home should be wired separately; In this way, if there is a circuit problem in that area, it will not affect other normal use.

(11) After we finish the wiring project, we must remember that every wire joint should be wrapped with waterproof insulating tape, and Party B will have an accident later.

Now, let's take a look at a group of practical operations on the construction site

How, this water and electricity decoration is not very standard, your home's water and electricity transformation is in accordance with this?
