山东电缆桥架在进行缆线敷设的时候除了要采用楼板沟槽和墙内埋管方式之外，在竖井和屋内天棚吊顶内也要采用电缆桥架。电缆桥架型式及品种的选择：

　　In the cable laying, in addition to the use of floor trench and wall buried pipe way, in the shaft and ceiling inside the house should also use the cable tray. Selection of cable tray types and varieties:

　　1、需屏蔽电气干扰的电缆网路或有防护外部(如：有腐蚀液休，易燃粉尘等环境)影响的要求时，应选用(FB)类槽式复合型防腐屏蔽电缆桥架(带盖)

　　1, the need to shield the electric cable network interference or external protection (such as: corrosion liquid, flammable dust and other environmental impact) requirements, should choose (FB) groove composite anti-corrosion shielding cable bridge (with cover)

　　2、强腐蚀性环境应采用(F)类复合环氧树脂防腐阻燃型电缆桥架。托臂、支架也要选用同样材料，提高桥架及附件的使用寿命，电缆桥架。在容易积灰和其它需遮盖的环境或户外场所宜加盖板。

　　2, strong corrosive environment should adopt (F) composite epoxy resin anti-corrosion flame retardant cable tray. The bracket will choose the same material, improve the service life of the bridge and annex, cable tray. Cover the floor in easy to dust and other environment or outdoor places that need to be covered.

　　3、除上述情况外，可根据现场还环境及技术要求选用山东电缆桥架型式及品种的选择托盘式、槽式、梯级式、玻璃防腐阻燃电缆桥架或钢质普通型桥架。在容易积灰和其它需遮盖的环境或户外场所宜加盖板。

　　3, in addition to the above, according to the requirements of site environment and technology selection of Shandong cable tray type and selection of varieties of tray type, channel type, ladder type, corrosion retardant glass or steel cable tray type bridge. Cover the floor in easy to dust and other environment or outdoor places that need to be covered.

　　4、在公共通道或户外跨越道路段，底层梯级的底部宜加垫板或在该段使用托盘 。大跨距跨越公共通道时，可根据用户要求提高桥架的载荷能力或选用行架。 5、大跨距(>3m)要选用复合型桥架(FB)。

　　4, in the public channel or outdoor crossing the road section, the bottom of the bottom of the ladder should be added to the plate or in the use of pallets. When the large span spans the public channel, the load capacity of the bridge or the frame can be improved according to the requirements of the users. 5, large span (>3m) to choose composite bridge (FB).

　　电缆桥架作为承载各种电缆敷设的载体，在从属于布线的需要，同样也要遵循上述原则并且加以实施，由于在一些大型的建筑物内，比如说大型的写字楼和金融办公楼等等.

　　As the carrier of all kinds of cable bridge cable laying, from which belongs to the wiring, also follow the above principles and to be implemented, because in some large buildings, such as a large office building and financial office buildings and so on.
