一、电缆桥架适用范围：

1、 Scope of application of cable tray:

高强度电缆桥架适用于电压在10千伏以下的电力电缆，以及控制电缆、照明配线等室内、室外或架空电缆、隧道电缆的敷设。结构特点与安装：高强度电缆桥架具有规格齐全、应用范围广、强度大、施工简单、配电灵活、安装标准、外表美观的特点，对施工过程中的技术改造、扩充电缆、维护检修带来方便。高强度电缆桥架的安装可因地制宜，可随工艺管道架空敷设、楼板、梁下吊装；室内处墙壁、柱壁、隧道、电缆沟壁上的侧装；还可在露天立柱支墩上安装；恒瑞万通厂家可配技术人员根据实际情况现场勘探测量并设计安装附件。

High strength cable trays are suitable for laying power cables with voltages below 10 kV, as well as indoor, outdoor, or overhead cables such as control cables, lighting wiring, and tunnel cables. Structural characteristics and installation: High strength cable trays have the characteristics of complete specifications, wide application range, high strength, simple construction, flexible power distribution, standard installation, and beautiful appearance, which brings convenience to technical transformation, cable expansion, maintenance and repair during the construction process. The installation of high-strength cable trays can be tailored to local conditions, and can be installed overhead with process pipelines, lifted under floor slabs, and beams; Side installations on indoor walls, column walls, tunnels, and cable trench walls; It can also be installed on outdoor column supports; Hengrui Wantong manufacturer can provide technical personnel to conduct on-site exploration, measurement, and design installation accessories according to the actual situation.

二、电缆桥架的结构形式：

2、 The structural form of cable tray:

1、常用电缆桥架有无孔托盘式、有孔托盘式、梯级式等形式，托盘式电缆桥架可广泛应用于石油、化工、电力、轻工、电视、电讯、煤炭等方面进行敷设电缆，它们具有造型美观、结构简单、安装方便等特点。梯级式电缆桥架适用于动力电缆的要求、也适用于控制电缆的敷设、也可在采用隔板后进行同一层电缆桥架敷设动力电缆和控制电缆。电缆桥架常用表面处理分为热镀锌、热浸镀锌、防火、喷塑四种；可以分别用于不同环境，在重腐蚀环境中应作特殊防腐处理。

1. Common cable trays include perforated tray type, perforated tray type, and stepped type. Tray type cable trays can be widely used for laying cables in petroleum, chemical, power, light industry, television, telecommunications, coal and other fields. They have the characteristics of beautiful appearance, simple structure, and easy installation. The stepped cable tray is suitable for the requirements of power cables, as well as for the laying of control cables. It can also be used to lay power and control cables on the same layer of cable tray after using partitions. Common surface treatments for cable trays include hot-dip galvanizing, hot-dip galvanizing, fireproofing, and spray coating; It can be used in different environments, and special anti-corrosion treatment should be carried out in heavily corrosive environments.

2、无孔托盘式电缆桥架是一种全封闭型电缆桥架，它适用于敷设计算机电缆、通信电缆、热电偶电缆及其它高灵敏系统的控制电缆等。它对控制电缆的屏蔽干扰和重腐蚀环境中电缆的防护都有较好效果。

2. Non perforated tray cable tray is a fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables, and control cables for other high-sensitivity systems. It has good effects on shielding interference of control cables and protecting cables in heavily corrosive environments.
