Lighting engineering implementation

The project in the late once a problem, will not be able to repair, so in the implementation must be carried out in accordance with the relevant norms, to avoid the short circuit, the line is not energized, lamp bracket is not fixed and so on. Before the installation of casing, according to the drawings and the actual situation, draw the line segments of pipeline and the position of the box, to mark the actual wall, marked by the amount of the actual installation segment size, recorded in the sketch, and then according to the sketch prefabrication. The manual pipe cutting saw, fixing pipes under pressure.

Engineering embedded mainly refers to lighting engineering, in order to match the progress of other projects, according to the site conditions, part of the lighting power supply lines and lighting fixtures need to be installed in advance. The utility model can be divided into the following parts: the laying of the cable trench or the lamp position, the laying of the wire or the cable sleeve, the threading in the pipe, the casting of the lamp base, the fixation of the lamp bracket, the backfill of the earth, etc.. The project in the late once a problem, will not be able to repair, so in the implementation must be carried out in accordance with the relevant norms, to avoid the short circuit, the line is not energized, lamp bracket is not fixed and so on.

Before the installation of casing, according to the drawings and the actual situation, draw the line segments of pipeline and the position of the box, to mark the actual wall, marked by the amount of the actual installation segment size, recorded in the sketch, and then according to the sketch prefabrication.

The manual pipe cutting saw, fixing pipes pressure clamp in case the pressure inside the firm, quasi dimension draw a good mark, hands push and pull hacksaw, evenly cut end, not broken, saw off pipe shall not turn aside, after using the circular saw and pipe wall edges down to. When the casing is laid, the saddle and the clamp are fixed, the fixed point is even, the SC20 card is 1.5m, the SC25 card is 2.0m.

To do the connection is tight, smooth mouth, full mouth care, orderly arrangement, no obvious wrinkle bending pipe, paint anti-corrosion integrity. Threading should be preceded by a steel wire into the pipeline to check whether it is smooth, according to the size of the pipe diameter to select the appropriate size of the mouth. Two people wear line, pull a wire feeding, less root number can be cut off at the front end of the wire insulation layer, and then the wire core is directly inserted into the coil wire, and bending die compaction, firm binding, tapered parts to form a smooth banding. The pipeline will be removed before the debris in the pipeline, the pipeline is longer or turn more, in the line at the same time to blow the right amount of talcum powder.

The wire is not allowed to penetrate into the connector and the local insulation damage and dead bend, the outer diameter of the conductor section does not exceed 40%. Pipeline should distinguish the color.
