從事電氣這行，有個大家每天都能看到，但是卻很少把他當回事的東西，就是機柜。大家可能更加關心柜內接線漂亮不漂亮，而忽略了柜子本體的好壞。

　　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.

　　在機柜行業，威圖是代表性的，同時國內的仿威圖廠家越來越多，市場也越來越大。以威圖柜子為例，機柜從構造上可分為：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.

　　威圖ES 為五折型材柜，PS為九折型材柜，TS為十六折型材柜。通常來說，折彎越多，柜子骨架的承重能力就越強。但是又不能無限的折下去。

　　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為德國威圖的，九折型材在很多年前到期后，國內出現了大量的廠商去仿，稱之為仿威圖。十六折的還在保護中，但是國內還是有很多廠商在仿制，畢竟市場空間大。偶爾有被打掉的。

　　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.

　　九折型材機柜是指因柱梁結構的折彎次數（9次）而命名。九折型材為封閉的柱梁結構，比傳統的開放梁柱、C型材結構強度高，受力大，造價低廉，占用空間小。下面圖片大家一目了然。相同的板材，如果經過十六道折彎相對PS九折型材多出7道折彎，使型材強度得到很大提高；對稱的型鋼截面設計，為靈活的并柜提供基礎（可以沿寬度、深度方向任意的并柜布局）。同時安裝基面增加到四個，有效安裝空間與九折系列相比，深度、寬度方向各增加50MM，整臺機柜安裝空間增加15%的空間。

　　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%.

　　機柜的質量，強度是很重要的一個方面，機柜的噴涂和EMC屏蔽的效果，也直接關系到產品的好壞。

　　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.

　　噴涂這方面，仿威圖柜這幾年整體質量上提升了不少，如果不是的人，看幾眼也分辨不出好壞。

　　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.

　　在防腐處理上，基本上是三重漆面處理，能提供理想的防腐蝕保護，而且穩定不受礦物油、潤滑油、乳液以及清潔用溶劑等的影響。

　　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.

　　底層目前大部分是磷化處理，高端一點的開始使用新的技術，納米納米陶瓷涂層。在防腐和方面，比傳統的處理工藝更好。中間層是電泳，通過電極的作用，電泳液會吸附在型材表面，形成一層20 ?m的保護膜。外面的一層是噴粉，根據要求，噴出不同的顏色。

　　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（電磁干擾）方面，各家的柜子也有差異。EMC一方面是保護柜內的器件不受外界的干擾，同時，柜內的這些干擾也盡可能少的散發出去，以免影響柜外其他設備的正常運行。通常EMC是在的電子所進行測試的。曾經在一個現場，將手機放在柜子旁邊，過會手機的觸摸屏就會自己亂跳，可見現場的電磁環境是多么的惡劣。一些莫名其妙的問題，也和EMC有關。

　　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.

　　售后服務發面，一般國內的機柜廠家的響應速度還是不錯，關鍵還是要看你的量。

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