槽式电缆桥架 二次电缆桥架主要是变电站使用，二次是相对于一次来说的，其实说白了这就是一常用的说法，二次电缆桥架也是桥架，根据加工安装形式分为梯式桥架和槽式桥架，可以根据电缆规模和设计要求采用多层布置的方法。

The secondary cable tray of trough type cable tray is mainly used in substations, and the secondary cable tray is relative to the primary one. In fact, this is a commonly used term. The secondary cable tray is also a tray, which can be divided into ladder type tray and trough type tray according to the processing and installation form. It can be arranged in multiple layers according to the cable scale and design requirements.

槽式电缆桥架具有适当的封闭性，在具体使用过程中的应用范围也广。不过很多人对于这方面的内容都并不是了解的，很多人对于这方面的内容都有着积极的态度。

The trough type cable tray has appropriate enclosure and a wide range of applications in specific use. However, many people are not familiar with this aspect, and many have a positive attitude towards it.

槽式电缆桥架主要应用于全封闭型的电缆铺设，在这方面具有不错的效果。如果各位能够较好的关注这方面的内容，各位还能够了解到在计算机电缆、通信电缆、高灵敏系统控制电缆等等各个方面该产品都是有着好的用途的。而且对于重度腐蚀的环境来讲，该产品的具体应用效果也是理想的，所以希望所有的朋友都能够以认真地态度来关注这方面的内容，较好的解决这方面的问题。对于整体的通信具有好的发展，起到积极地影响。 不锈钢网格桥架在各类的电缆桥架当中占较大的优势。一般表现在隔热和散热还有防火等方面的改进。其结构主要是使用复合型，和双重的隔热效果，并且可以内外阻燃和防火，与此同时还可以具有适当的抽风的散热的性能和着火自灭。不锈钢的网格桥架的内槽主要是应用了玻璃纤维来增强塑料和各种的阻燃形式的防火材料形成的，其外表面还使用涂覆防火的涂料隔离，不锈钢网格桥架的水平燃烧和垂直燃烧还有暗热的长度等到标准

The trough type cable tray is mainly used for fully enclosed cable laying and has a good effect in this regard. If you can pay good attention to this aspect, you can also understand that this product has good uses in various fields such as computer cables, communication cables, high-sensitivity system control cables, etc. Moreover, for environments with severe corrosion, the specific application effect of this product is also ideal. Therefore, we hope that all friends can pay attention to this aspect with a serious attitude and solve this problem better. It has a positive impact on the overall development of communication. Stainless steel mesh cable trays have a significant advantage among various types of cable trays. Generally manifested in improvements in insulation, heat dissipation, and fire prevention. Its structure mainly uses composite materials and dual insulation effects, and can be flame retardant and fire-resistant both inside and outside. At the same time, it can also have appropriate ventilation and heat dissipation performance, as well as self extinguishing during ignition. The inner groove of stainless steel grid bridge is mainly formed by using glass fiber to reinforce plastic and various flame retardant materials. The outer surface is also insulated with fire-resistant coating. The horizontal and vertical combustion of stainless steel grid bridge, as well as the length of dark heat, meet the standard
