玻璃防腐阻燃电缆桥架的优势
1, the bridge through the building deformation and straight line section more than 30m, set the compensation device, the bridge gap at both ends of the soft copper conductor cross, and leave telescopic margin. For vibration sites, spring loops shall be installed at the connections to the ground.
2、若设计要求把桥架作为接地干线的一部分，则要求遵守电缆桥架安装规范在接头处的连接电阻不应大于0.00033Ω。若利用桥架连接板达不到这个要求，即使是镀锌桥架，也应用符合设计要求的软铜导线跨接。
2, if the design requirements of the bridge as part of the ground line, then comply with the requirements of the cable bridge installation specifications, the joint resistance shall not be greater than 0.00033. If the bridge connecting plate does not meet this requirement, even the galvanized bridge, also meet the requirements of the design of soft copper wire jumper.
3、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)
Cable network 3, shielding electrical interference or external protection (such as: a corrosive liquid Hugh, flammable dust and other environmental effects) requirements, should choose (FB) type groove type composite type anti-corrosion shielding cable tray (with cover)
4、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。
4, 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 panels in easy ash and other environment or outdoor areas that need to be covered.
5、除上述情况外，可根据现场还环境及技术要求选用托盘式、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。
5, in addition to the above circumstances, according to the site environment and technical requirements, choose pallet, trough, step type, glass anti-corrosion flame retardant cable bridge or steel ordinary type bridge. Cover panels in easy ash and other environment or outdoor areas that need to be covered.
6、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。
6, in public 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 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.
