槽式电缆桥架是一种全封闭型的电缆桥架。用整张钢板弯制而成。按照长度分为普通槽式电缆桥架和大跨距槽式电缆桥架。普通槽式电缆桥架一般长度为2米，桥架底板与侧板一般是由一块板材压制而成，大跨距槽式电缆桥架长度有3米、4米、6米几种，桥架侧板一般采用瓦楞型以增强单位长度内的安全载荷，桥架底板与侧板通过焊接固定在一起。

The trough type cable tray is a totally enclosed cable tray. Made by bending the entire steel plate. According to the length, it can be divided into ordinary trough cable tray and long-span trough cable tray. The general length of ordinary trough cable tray is 2m. The bottom plate and side plate of the cable tray are generally pressed by one plate. The length of long-span trough cable tray is 3m, 4m and 6m. The side plate of the cable tray is generally corrugated to enhance the safety load within the unit length. The bottom plate and side plate of the cable tray are fixed together by welding.

槽式直线段电缆桥架弯头常见的规格型号有槽式90度水平弯通电缆桥架、槽式45度水平弯通电缆桥架、槽式水平三通电缆桥架、槽式水平四通电缆桥架、槽式垂直上弯通电缆桥架、槽式垂直下弯通电缆桥架和槽式垂直三通电缆桥架等。

Common specifications and models of cable tray elbows in trough straight section include trough type 90 degree horizontal bend through cable tray, trough type 45 degree horizontal bend through cable tray, trough type horizontal tee cable tray, trough type horizontal cross cable tray, trough type vertical upward bend through cable tray, trough type vertical downward bend through cable tray, and trough type vertical tee cable tray.

槽式电缆桥架按照镀锌工艺分为电镀锌槽式电缆桥架和热浸镀锌槽式电缆桥架，电镀锌槽式电缆桥架是通过金属电溶解技术来把锌离子附着到桥架表面，热浸锌槽式电缆桥架是通过锌融液涮洗在桥架表面生成一层合金层。热浸镀锌的锌层厚度比电镀锌锌层厚度要厚不少。

According to the galvanizing process, the trough cable tray can be divided into electrogalvanized trough cable tray and hot-dip galvanized trough cable tray. The electrogalvanized trough cable tray attaches zinc ions to the surface of the bridge through metal electrodissolution technology, and the hot-dip galvanized trough cable tray generates an alloy layer on the surface of the bridge through rinsing with zinc melt. The thickness of the zinc layer in hot-dip galvanizing is much thicker than that in electric galvanizing.

山东电缆桥架厂家提醒，槽式桥架默认是不能防火的，喷涂防火漆或者防火粉末后，桥架表面涂层就有了防火阻燃的特性，也就能够防火了。镀锌槽式电缆桥架还可以进行喷涂工艺处理，喷涂防火粉末后就具有了防火阻燃的性能，可以当作防火桥架来使用。

The manufacturer of cable tray in Shandong reminded that the trough type cable tray is not fireproof by default. After spraying fireproof paint or fireproof powder, the surface coating of the cable tray has the characteristics of fire resistance and flame retardancy, and can also be fireproof. Galvanized trough cable tray can also be treated by spraying process. After spraying fire retardant powder, it has fire retardant performance and can be used as a fire resistant cable tray.

喷塑槽式防火电缆桥架通过喷涂热固性防火静电粉末制作而成具有防火阻燃特性的电缆桥架。在密封式环境下更能保护电缆电线，屏蔽性能非常好，使空气中的灰尘和污渍无法污染桥架内的电缆，屏蔽信号干扰能力强，配上静电粉末喷塑功效，能防静电、防锈、防水、增加荷载能力等。经过静电喷塑加工后，桥架外表比较光滑，配上不同的颜色能大大提高美观度。

The plastic sprayed trough type fireproof cable tray is made by spraying thermosetting fireproof electrostatic powder to form a cable tray with fireproof and flame retardant characteristics. In a sealed environment, it can better protect cables and wires, with excellent shielding performance, preventing dust and stains in the air from polluting the cables inside the bridge. It has strong shielding signal interference ability, and is equipped with electrostatic powder spraying effect, which can prevent static electricity, rust, waterproof, and increase load capacity. After electrostatic spraying processing, the appearance of the bridge is relatively smooth, and adding different colors can greatly improve its aesthetics.

槽式电缆桥架水平安装时，应该按照载荷规范选择支、吊架间距，佳距离不应该大于2米。槽式电缆桥架支、吊架的间距也要参考其产品性能参数说明来设置。两段槽式电缆桥架的连接处或者活动连接板处，应该采用黄绿线或铜编织线进行两端的连接，连接线的横截面积不应该小于16平方毫米。钢制槽式电缆桥架在出入建筑物时，应与就近的总等电位接地装置相连接。

When the trough type cable tray is installed horizontally, the spacing between supports and hangers should be selected according to the load specification, and the optimal distance should not be more than 2m. The spacing between supports and hangers of trough type cable tray shall also be set according to the product performance parameters. Yellow green wire or copper braided wire shall be used at the connection of two section trough cable tray or at the movable connecting plate for connection at both ends, and the cross sectional area of the connecting wire shall not be less than 16 square millimetre. The steel trough type cable tray shall be connected with the nearest general equipotential grounding device when entering and exiting the building.

槽式桥架应用范围：地下室车库、厂房输电、输变电站，地铁站飞机场，发电厂，核电厂，智能化工业厂房等电缆使用多的场合。如果您对其有所疑惑或者需求，就来我们网站 //www.comprepyme.com留言看看吧！
