Due to too many actual specifications, we can't list them all. After our understanding of the market, if you don't have the specifications you want, please consult our customer service immediately, and our customer service will give you a complete quotation.

强腐蚀性环境应采用(F)类复合环氧树脂防腐阻燃型弱电桥架。

Class (F) composite epoxy resin anti-corrosion flame-retardant weak current bridge shall be used in highly corrosive environment.

托臂、支架也要选用同样材料，提高桥架及附件的使用寿命，弱电桥架。

Brackets and supports should also be made of the same materials to improve the service life of bridges and accessories, and weak current bridges.

在容易积灰和其它需遮盖的环境或户外场所宜加盖板。

Cover plates should be added in the environment or outdoor places that are easy to accumulate dust and need to be covered.

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、玻璃防腐阻燃弱电桥架或钢质普通型桥架。

In addition to the above situations, tray type, trough type, cascade type, glass corrosion resistant flame retardant weak current bridge or steel common type bridge can be selected according to the site, environment and technical requirements.

 

电缆桥架的大载荷和支撑间距应小于允许载荷和允许支撑间距，安装工程中不得载人，如现场环境确实有必要时，需有保障设施方可载人，不得让不合格非人员操作。

The large load and support spacing of the cable tray shall be less than the allowable load and support spacing, and no person shall be carried in the installation project. If the site environment is really necessary, safety guarantee facilities shall be provided to carry people, and unqualified non-professional personnel shall not be allowed to operate.

再将表面处理过的立柱、托臂支架等等采用膨胀螺栓固定在墙面上(得在混凝土构体和实心砖墙体，不得在空心砖墙)，对现场焊接处做好防腐处理，现场进行涂刷反腐漆，电缆桥架敷设时，桥架之间的对接处支撑点尽量设置在跨距的1/4左右处。

After that, the columns and brackets with surface treatment shall be fixed on the wall with expansion bolts (only in concrete structure and solid brick wall, not in hollow brick wall), the anti-corrosion treatment shall be carried out on the site welding site, and the anti-corrosive paint shall be painted on the site. When laying the cable bridge, the support point at the junction between the bridge frames shall be set at about 1/4 of the span as far as possible.

CQ1-T型梯级式电缆桥架是根据国内外有关资料而改进设计的。它具有重量轻、成本低、造型别具、安装方便、散热、透气好等优点。

CQ1-T stepped cable tray is improved and designed according to relevant domestic and foreign data. It has the advantages of light weight, low cost, unique shape, convenient installation, heat dissipation and good ventilation.

他适用于一般直径较大电缆的敷设，适合于高、低压动力电缆的敷设。

It is suitable for the laying of general cables with large diameter and for the laying of high and low voltage power cables.

托盘式电缆桥架是石油、化工、轻工、电讯等方面应用广泛的一种。它具有重量轻、载荷大、造型美观、结构简单、安装方便等优点。它即适用于动力电缆的安装，也适合于控制电缆的敷设。

Tray type cable tray is widely used in petroleum, chemical, light industry, telecommunications and other fields. It has the advantages of light weight, large load, beautiful shape, simple structure and convenient installation. It is not only suitable for the installation of power cables, but also suitable for the laying of control cables.
