Wiring principle
Horizontal and vertical. Use special Cai Zhong PVC flame retardant conduit, which must be fixed in the conduit. When the conduit box is connected with the conduit, lock nuts shall be used, and a pipe clamp shall be used every 80 cm for the straight pipe and every 20 cm for the corner.
Socket installation
In the upper part of the wall, the wall should be grooved vertically upward to the top of the wall to install decorative corner lines. If it is in the lower part of the wall, it should be grooved vertically downwards to the bottom of the skirting board, and the groove depth is consistent. After the groove line and top straight line pop up on the wall surface, cut the wall surface with a cutting machine and slot it with a machine.
Use Cai Zhong PVC pipe.
When bending a pipe, now use a spring instead of a 90-degree elbow tee. When installing the line, it is necessary to add a protective wire sleeve and glue it. The edges of sleeves are tight, straight and smooth. At the right-angle corner, it should be cut at the inner side of the corner, and one side of the cut should be cut into an arc joint, and then it should be bent and installed.
pipe joint
Pipe thread depth is moderate, without burr. Wrap the joint of the pipeline with raw material tape for 5 -6 times, and the number of winding teeth of the pipeline is 5-6, until the joint is tightened, and rotten teeth are not allowed to be inserted into the pipe.
Metal wire fixation method
After the wire is put into the casing, it should be fixed on the wall and wall with wire fixing tools, and then plastered for concealment.
pipe laying
It is forbidden to lay the conduit directly under the composite board, and the conduit under the solid wood floor must be reinforced. It is forbidden to lay the catheter on the kitchen and bathroom floor to prevent water from infiltrating into the catheter. There must be no conduit on the floor of the bathroom, which must be strengthened. )
Wire inlet box
When the conductor enters the box, it must be guaranteed to have a certain length, which is 10 ~ 15cm, and the audio frequency is 100cm. When installing and maintaining switches and sockets, please put on hoses.
Distance between water injection pipe and wall surface
The distance between the water injection pipe and the wall should be 1.5cm, and the distance between them should be 15cm.
The distance between the wire and the water pipe
The parallel distance between wires and water pipes should not be less than 30 cm, and the crossing distance should not be less than 10 cm.
Line point and point
There can be no joints between wires, and the hidden wires in the ceiling must be protected by flame retardant pipes.
Hydropower acceptance
After the acceptance of water and electricity, the wire trough can be leveled, and the wall trough is filled with 1: 3 cement mortar (the wall is leveled twice. )
