High-strength cable bridge can be installed according to local conditions. It can be laid overhead along with the process pipeline and hoisted under the floor and beam; Side installation of indoor wall, column wall, tunnel and cable trench wall; It can also be installed on open-air column piers; According to the actual situation, the cable bridge can assign technicians to carry out on-site survey and design and install accessories.

二、电缆桥架的结构:

2、 Structure of cable tray:

1.常用的电缆槽有无孔槽式、有孔槽式、阶梯式等。托盘式电缆桥架可广泛用于石油、化工、电力、轻工、电视、电信、煤炭等行业的电缆敷设。它们具有外形美观、结构简单、安装方便的特点。

1. Commonly used cable trays include holeless, holed and stepped cable trays. Tray type cable tray can be widely used for cable laying in petroleum, chemical, electric power, light industry, television, telecommunications, coal and other industries. They are characterized by beautiful appearance, simple structure and convenient installation.

本发明适用于电力电缆和控制电缆的敷设要求，采用隔板后，电力电缆和控制电缆也可以敷设在同一层电缆槽内。电缆桥架常见的表面处理分为热浸镀锌、热浸镀锌、防火、喷塑四种。可分别在不同的环境下使用，在重腐蚀环境下要做特殊的防腐处理。

The invention is applicable to the laying requirements of power cables and control cables. After the partition is adopted, the power cables and control cables can also be laid in the same layer of cable trench. Common surface treatment of cable tray includes hot-dip galvanizing, hot-dip galvanizing, fire prevention and plastic spraying. It can be used in different environments, and special anti-corrosion treatment shall be carried out in the heavily corrosive environment.

2.无孔托盘式电缆桥架是一种全封闭的电缆桥架，电缆桥架适合敷设计算机电缆、通信电缆、热电偶电缆以及其他高灵敏系统的控制电缆。对控制电缆的屏蔽干扰和重腐蚀环境下电缆的保护有很好的效g。

2. The holeless tray type cable bridge is a fully enclosed cable bridge. The cable bridge is suitable for laying computer cables, communication cables, thermocouple cables and control cables of other highly sensitive systems. It has good effect on shielding interference of control cable and cable protection under heavy corrosion environment.
