从事电气这行，有个大家每天都能看到，但是却很少把他当回事的东西，就是机柜。大家可能更加关心柜内接线漂亮不漂亮，而忽略了柜子本体的好坏。

　　In the field of electrical engineering, there is something that everyone sees every day but rarely takes seriously, which is the cabinet. People may be more concerned about the beauty of the wiring inside the cabinet, while ignoring the condition of the cabinet itself.

　　在机柜行业，威图是代表性的，同时国内的仿威图厂家越来越多，市场也越来越大。以威图柜子为例，机柜从构造上可分为：五折型材柜，九折型材柜，十六折型材柜等。

　　In the cabinet industry, Weitu is the most representative, and at the same time, there are more and more domestic manufacturers imitating Weitu, and the market is also growing. Taking Weitu cabinets as an example, cabinets can be divided into five fold profile cabinets, nine fold profile cabinets, sixteen fold profile cabinets, etc. in terms of structure.

　　威图ES 为五折型材柜，PS为九折型材柜，TS为十六折型材柜。通常来说，折弯越多，柜子骨架的承重能力就越强。但是又不能无限的折下去。

　　Weitu ES is a five fold profile cabinet, PS is a nine fold profile cabinet, and TS is a sixteen fold profile cabinet. Generally speaking, the more bends there are, the stronger the load-bearing capacity of the cabinet frame. But it cannot be infinitely folded down.

　　九折和十六折型材均为德国威图的，九折型材在很多年前到期后，国内出现了大量的厂商去仿，称之为仿威图。十六折的还在保护中，但是国内还是有很多厂商在仿制，毕竟市场空间大。偶尔有被打掉的。

　　Both the nine fold and sixteen fold profiles are patents of German Weitu. After the expiration of the nine fold profile patent many years ago, a large number of domestic manufacturers began to imitate it, known as imitating Weitu. The 16% off patent is still under protection, but there are still many domestic manufacturers imitating it because of the large market space. Occasionally, they are knocked out.

　　九折型材机柜是指因柱梁结构的折弯次数（9次）而命名。九折型材为封闭的柱梁结构，比传统的开放梁柱、C型材结构强度高，受力大，造价低廉，占用空间小。下面图片大家一目了然。相同的板材，如果经过十六道折弯相对PS九折型材多出7道折弯，使型材强度得到很大提高；对称的型钢截面设计，为灵活的并柜提供基础（可以沿宽度、深度方向任意的并柜布局）。同时安装基面增加到四个，有效安装空间与九折系列相比，深度、宽度方向各增加50MM，整台机柜安装空间增加15%的空间。

　　The nine fold profile cabinet is named after the number of bending cycles (9 times) of the column beam structure. The nine fold profile is a closed column beam structure, which has higher strength, greater stress, lower cost, and occupies less space than traditional open beam column and C-profile structures. The following picture is clear to everyone at a glance. If the same board undergoes sixteen bends, it will have an additional seven bends compared to the PS nine fold profile, which greatly improves the strength of the profile; Symmetrical steel section design provides a foundation for flexible cabinet consolidation (allowing for arbitrary cabinet layout along width and depth directions). At the same time, the installation base has been increased to four, and the effective installation space has increased by 50MM in both depth and width directions compared to the nine fold series. The installation space of the entire cabinet has increased by 15%.

　　机柜的质量，强度是很重要的一个方面，机柜的喷涂和EMC屏蔽的效果，也直接关系到产品的好坏。

　　The quality and strength of the cabinet are important aspects, and the coating and EMC shielding effect of the cabinet directly affect the quality of the product.

　　喷涂这方面，仿威图柜这几年整体质量上提升了不少，如果不是的人，看几眼也分辨不出好坏。

　　In terms of spraying, the overall quality of the imitation Weitu cabinet has improved significantly in recent years. If you are not a professional, you cannot distinguish between good and bad even after a few glances.

　　在防腐处理上，基本上是三重漆面处理，能提供理想的防腐蚀保护，而且稳定不受矿物油、润滑油、乳液以及清洁用溶剂等的影响。

　　In terms of anti-corrosion treatment, it is basically a triple paint treatment, which can provide ideal anti-corrosion protection and is stable against the influence of mineral oil, lubricating oil, lotion and cleaning solvents.

　　底层目前大部分是磷化处理，高端一点的开始使用新的技术，纳米纳米陶瓷涂层。在防腐和方面，比传统的处理工艺更好。中间层是电泳，通过电极的作用，电泳液会吸附在型材表面，形成一层20 ?m的保护膜。外面的一层是喷粉，根据要求，喷出不同的颜色。

　　At present, most of the bottom layer is treated with phosphating, while high-end ones are starting to use new technologies such as nano ceramic coatings. In terms of anti-corrosion and environmental protection, it is better than traditional treatment processes. The middle layer is electrophoresis, and through the action of electrodes, the electrophoresis solution will adsorb onto the surface of the profile, forming a layer of 20? M's protective film. The outermost layer is powder coating, which sprays different colors according to requirements.

　　在屏蔽EMC（电磁干扰）方面，各家的柜子也有差异。EMC一方面是保护柜内的器件不受外界的干扰，同时，柜内的这些干扰也尽可能少的散发出去，以免影响柜外其他设备的正常运行。通常EMC是在的电子所进行测试的。曾经在一个现场，将手机放在柜子旁边，过会手机的触摸屏就会自己乱跳，可见现场的电磁环境是多么的恶劣。一些莫名其妙的问题，也和EMC有关。

　　In terms of shielding EMC (electromagnetic interference), each cabinet also has differences. On the one hand, EMC protects the components inside the cabinet from external interference, and at the same time, minimizes the emission of these interferences inside the cabinet to avoid affecting the normal operation of other equipment outside the cabinet. EMC is usually tested in professional electronics. I once placed my phone next to a cabinet at a scene, and after a while, the touch screen of my phone would jump around on its own, which shows how harsh the electromagnetic environment was on site. Some inexplicable issues are also related to EMC.

　　售后服务发面，一般国内的机柜厂家的响应速度还是不错，关键还是要看你的量。

　　Regarding after-sales service, the response speed of domestic cabinet manufacturers is generally good, but it depends on your quantity.
