电缆桥架分为槽式电缆桥架、托盘式电缆桥架、梯级式电缆桥架、网格桥架等，由支架、托臂和安装附件等组成。可以独立架设, 也可以敷设在各种建(构)筑物和管廊支架上，体现结构简单、造型美观、配置灵活和维修方便等特点，全部零件均需进行镀锌处理，安装在建筑物外露天的桥架，如果是在邻近海边或属于腐蚀区，则材质必须具有防腐、耐潮气、附着力好， 耐冲击强度高的物性特点。

　　Cable trays are divided into trough cable trays, tray cable trays, ladder cable trays, grid cable trays, etc., consisting of brackets, support arms, and installation accessories. It can be independently erected or laid on various buildings and pipe gallery supports, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration, and easy maintenance. All parts need to be galvanized and installed on the bridge outside the building. If it is near the seaside or in a corrosive area, the material must have physical properties such as anti-corrosion, moisture resistance, good adhesion, and high impact strength.

　　槽式电缆桥架是用整张钢板弯制而成的槽式部件，其概念上与盘架的区别是高、宽比不同，盘架浅而宽，槽式电缆桥架具有一定的深度和封闭性。槽式玻璃钢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。而且槽式电缆桥架其材质有不锈钢、铝合金、钢质三种。

　　A trough type cable tray is a trough type component made by bending a whole steel plate. Its conceptual difference from a tray is the height to width ratio. The tray is shallow and wide, while the trough type cable tray has a certain depth and enclosure. The trough type fiberglass cable tray is a fully enclosed cable tray, which is most suitable for laying computer cables, communication cables, thermocouple cables, and control cables of other high-sensitivity systems. It has good effects on shielding interference of control cables and protecting cables in heavily corrosive environments. And the material of trough cable tray includes three types: stainless steel, aluminum alloy, and steel.

　　槽式玻璃钢桥架的护罩随槽体配套供货，其它配件与梯级式、托盘式桥架通用。表面处理分为镀锌、防火、静电喷塑、热浸锌等，在重腐蚀环境中可特殊防腐处理。托盘式电缆桥架托盘式电缆桥架是石油、化工、轻工、电视、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。它既适用于动力电缆的安装，也适合于控制电缆的敷设。梯级式电缆桥架梯级式电缆桥架具有强度大、重量轻、成本低、造型美观、安装方便、透气性好等特点。它适用于一般直径较大电缆的铺设，特别适用于载荷大的高低压电缆的铺设。

　　The protective cover of the trough type fiberglass bridge is supplied with the trough body, and other accessories are compatible with the stepped and tray type bridge. Surface treatment can be divided into galvanizing, fireproofing, electrostatic spraying, hot-dip galvanizing, etc., and special anti-corrosion treatment can be carried out in heavily corrosive environments. Tray type cable tray is the most widely used type in petroleum, chemical, light industry, television, telecommunications and other fields. It has the advantages of light weight, large load capacity, beautiful appearance, simple structure, and easy installation. It is suitable for both the installation of power cables and the laying of control cables. Cascade cable tray has the characteristics of high strength, light weight, low cost, beautiful appearance, easy installation, and good breathability. It is suitable for laying cables with larger diameters, especially for laying high and low voltage cables with large loads.

　　网格桥架网格桥架适用于电力、通讯电缆布线，是作为传统桥架的延伸。提高了系统升级和维护能力，为升级留有余地，在综合布线系统可以灵活应用，适用于布线桥架的上下走线。线路和设备的检修非常快速。网格桥架节省了二次重复投资的昂贵成本。自重仅是传统桥架的1/5，比传统桥架节省2/3的安装时间，布线系统和周边生产环境更清洁，卫生和美观。网状的机构使它的散热更好,有效的延长线缆的使用寿命。

　　Grid cable tray is suitable for power and communication cable wiring and is an extension of traditional cable trays. Improved system upgrade and maintenance capabilities, leaving room for upgrades, and can be flexibly applied in the comprehensive cabling system, suitable for the up and down routing of cabling trays. The maintenance of lines and equipment is very fast and safe. The grid bridge saves the expensive cost of secondary repeated investment. The self weight is only 1/5 of traditional cable trays, saving 2/3 of installation time. The wiring system and surrounding production environment are cleaner, more hygienic, and aesthetically pleasing. The mesh like structure improves its heat dissipation and effectively extends the service life of the cable.
