iron pipe) and fix it well to prevent it from moving.
Excessive line connectors and improper handling of connectors are the prominent reasons.
The TV antenna line and telephone line shall go through casing pipes respectively.
Common are: the wall line is broken by electric hammer, and the air nail gun pierces the PVC pipe or sheath line when paving the floor.
If the casing is not sleeved or inappropriate casing is used, the line damage can not be avoided during construction or in future use, which will leave hidden dangers for you.

Therefore, in circuit management, we must strengthen supervision…
For the sake of decoration safety, analysis of the most common problems in circuit engineering construction in the electrical stage of decoration.
Safety involves family members and neighborhood safety.
Circuits and power transformation and distribution equipment must be planned and carefully arranged according to the on-site power consumption, so as to effectively reduce accidents, especially accidents caused by circuits.
Treatment and analysis of safety problems in circuit construction: 1.
Try to reduce joints in the line as much as possible.
The completed line is damaged by subsequent construction.
The practice of telephone line is similar to that of TV line.

Common problems in circuit construction: 1.
PVC rigid conduit shall be used for concealed lines on the wall, and attention shall be paid to matching with the wire number; The ground routing shall take into account that it will be under pressure for a long time in the future and will be affected during construction, so it is best to use water gas pipe (i.e.
If conditions permit, it can also “rinse tin” or use wiring terminals; The coaxial cable connection of TV antenna is best to use a splitter or junction box.
This is why.
There is no casing for the concealed lines, which only cut corners to reduce costs.
Different lines follow the same line.
Some lines are too long, and some joints will be produced during electrician operation.
The different rated current of wires of different specifications is not considered for the distribution line, and the “small horse pulling the big cart” causes the long-term overload of the line itself.
According to the power consumption position, the distribution box shall be set on the electric column of the main line first to prevent the maintenance electrician from connecting with the electric pole frequently, so as to reduce electrical failure and electric shock accidents.
However, due to the limitation of some electricians’ technical level and perhaps the lack of sense of responsibility, if the wiring, insulation and moisture-proof treatment of the joint are not good, there will be open circuit, short circuit and other phenomena.
We all know that safety is very important in home decoration.
In the process of construction, the potential safety hazards of electricity must not be underestimated.
High voltage lines shall not be erected in the construction site, and the main lines entering the site shall be as few as possible.
Last year, there was a report about the damp and electrified walls of a house.
Circuit construction is the most involved in decoration safety.

Circuit is also an important problem that causes potential safety hazards.
3.
Pay attention to its rated current when selecting distribution lines and wires.
If wiring is necessary, the distribution line shall be connected well, insulated and moisture-proof.
Concealed lines shall be marked to avoid being inadvertently damaged by the construction personnel of the next process.
If the TV antenna, telephone line and distribution line are threaded into the same sleeve, the reception of TV and telephone will be disturbed.

Casing is to protect the hidden line from damage.
On the surface, electrician construction does not seem to be many, but many potential problems have left many dangerous hidden dangers for your future life.
