保定专业水电改造施工

施工进场——定位——设计线路——开槽——穿线——封槽——线路测试——安装暗盒，开关，插座面板——验收——安装——验收。

The construction approach -- the orientation of design - line - thread - slotted sealing groove - line test - mounted cassette switch socket panel - Installation - acceptance - acceptance.

1、定位：首先要根据你对电的用途进行电路定位，比如，那里要开关、那里要插座、那里要灯等要求，电工会根据你的要求进行定位。

1, positioning: first, according to your purpose of electric circuit location, for example, there are switches, plugs, lights and other requirements, electricians will be positioned according to your requirements.

2、开槽：定位完成后，电工根据定位和电路走向，开布线槽，线路槽很有讲究，要横平竖直，不过，规范的做法，不允许开横槽，因为会影响墙的承受力。

2, slotting: after the positioning is completed, the electrician according to the location and circuit direction, open the wiring slot, the line slot is very particular, must be horizontal and vertical. However, the standard practice is not allowed to open the transverse slot, because it will affect the bearing capacity of the wall.

3、布线：布线一般采用线管暗埋的方式。线管有冷弯管和PVC管两种，冷弯管可以弯曲而不断裂，是布线的最好选择，因为它的转角是有弧度的，线可以随时更换，而不用开墙。

3, wiring: the wiring generally adopts the way of the wire tube buried. There are two kinds of cold pipe and PVC tube. The cold bending pipe can bend without breaking. It is the best choice for wiring, because its rotation angle is radian, and the line can be changed at any time, instead of opening the wall.

4、弯管：冷弯管要用弯管工具，弧度应该是线管直径的10倍，这样穿线或拆线，才能顺利。

4, bend: the cold bend tube must use the elbow tool, the arc should be 10 times the diameter of the line tube, so that the line or disassembly line can be smooth.

5、穿线：管内所穿电线的总横截面积不能超过线管横截面积的60%，一般情况是在相匹配的管内的线数最好不要超过3根，这样才能充分保证是活线而不是死线。

5, wear line: wire wear tube the total cross-sectional area of not more than 60% line pipe cross-sectional area, the general situation is in the matching pipe line number is best not more than 3, so as to fully guarantee the live line rather than a deadline.
