Electric System Project1. 电气系统安装工艺流程 Installation process2. 钢管敷设 Pipe Laying1) 电线管路明敷设时，固定点间距应均匀，固定点设置见下图： When adopted surface conduit,the distance between fixed points shall be uniform.The fixed points position as follows:2) 钢管路沿墙明敷设需进入接线盒时，其固定管卡应采用离墙码，以保
2、证管路进入接线盒平直，如下图所示：When the wall-following pipe adopted surface conduit to connect with junction box,the clamp shall use 离墙码 to ensure the pipe horizontal and vertical. 3) 钢管路沿墙明敷设需进入配电箱时，应一孔一管，管道应从配电箱预留敲落孔进入，配管需要煨制灯叉弯或安装支架。不少于两根管路与配电箱连接时，应排列整齐，间距均匀。如下图所示When the wall-following pipe adopted surface co
3、nduit to connect with junction box,it must follow the rule”one hole ,one pipe”.The pipe shall go through the reserved hole to junction box while tubing laying need installing support.When there are more than 2 pipes connected with junction box,those pipes shall be neat and uniform spacing as follows
4、: 4) 钢管连接及接地的各种不同方式见下图: Pipe connecting and grounding in different ways as follows :3. 桥架安装Cable Tray Installationa) 槽式水平桥架与支架的横担必须用半圆头的螺栓固定，半圆头向内，以防止螺栓划伤电缆外护层。 Adopting cross-arm cup head bolt to fix support cross-arm on channel tray ,the cup-head side shall be inward in case the bolt will scratch
5、the cable sheath .c) 电缆桥架沿墙垂直安装时，应确保桥架固定牢靠，梯架的固定应采用专用压板。如下图。When install cable tray along wall vertically, make sure that cable tray fixed firmly.Adopting specialized plate pinch to fix cable ladder. d)槽式电缆桥架沿墙安装时，其固定方式应采用支架或半圆头内膨胀螺栓，固定螺栓的螺杆严禁伸进桥架内，如下图：When install channel tray along the wall, adopt
6、ing support or cup-head expansion bolt to fix. It is forbidden to The screw is strictly forbidden into the cable tray.As follows:e)水平安装电缆桥架应在结构主梁上安装固定支架，在主梁之间平均分配间隔距离安装吊架，支吊架间隔距离应符合1.53m的要求。如下图： When install cable tray horizontally ,erect fixed support on main beam.The main beam is divided into unif
7、orm spacing on which install the suspended frame.The distance between fixed support and suspended frame shall be 1.53m. As follows:f)非镀锌（喷塑、防火）钢制电缆桥架连接时，应在连接板处安装跨接地线，跨接地线安装应注意安装爪型垫圈，以保证接地的电气通路。如下图所示：When install non-galvanized(plastic spray,fireproofing)steel cable tray,laying the ground wire at jun
8、ction plate,claw washer shall be installed with ground wire to make sure system running normally.h)桥架在穿防火分区时，对桥架与建筑物之间的缝隙做防火处理，防火材料须能防火3小时以上，具体的做法见下图。When cable tray across the fire compartment,make the fire prevention between cable tray and buildings.The materials shall be fire-proof more than 3 ho
