在工業控制柜領域，仿威圖機柜幾乎成了一個品類的代名詞。其核心魅力在于以九折型材為骨架的框架結構——一種將力學性能、模塊化設計和制造成本平衡到出彩的工程方案。

In the field of industrial control cabinets, imitation Weitu cabinets have almost become synonymous with a category. Its core charm lies in the frame structure with nine fold profiles as the skeleton - an engineering solution that balances mechanical performance, modular design, and manufacturing costs to the extreme.

九折型材，顧名思義，是將冷軋鋼板通過輥壓線經九次折彎成型的一種特殊型材。這種型材作為機柜的“骨架”，通過優良專用三通焊接成整體框架。框架結構的好處是多維度的：頂板、底板、側板、門板、裝置板等部件通過螺絲固定在框架上，既提高了機柜的剛度和強度，又實現了面板的可拆卸性。單柜承重普遍可達500-1500KG，部分設計甚至可達2000KG，足以應對變頻器、重型斷路器等各種重型電氣設備的安裝需求。

Nine fold profile, as the name suggests, is a special profile formed by bending cold-rolled steel plates nine times through a rolling line. This type of profile serves as the "skeleton" of the cabinet and is welded into a complete frame through high-quality specialized tees. The advantage of the frame structure is multidimensional: the top plate, bottom plate, side plate, door panel, device board and other components are fixed to the frame with screws, which not only improves the rigidity and strength of the cabinet, but also realizes the disassembly of the panel. The load-bearing capacity of a single cabinet can generally reach 500-1500KG, and some designs can even reach 2000KG, which is sufficient to meet the installation needs of various heavy-duty electrical equipment such as frequency converters and heavy-duty circuit breakers.

材料配置方面，仿威圖機柜有著成熟的行業慣例：門板厚度2.0mm，柜體（背板、側板）1.5mm，安裝板2.5mm（部分廠家可選3.0mm）。材質多選用優良冷軋鋼板，特殊場景（如化工、戶外）可選用304或316不銹鋼。表面處理采用靜電噴粉工藝，前處理包含脫脂、酸洗、磷化、鈍化等多道工序，漆膜厚度可達40-60μm。顏色以RAL7032或RAL7035兩種織紋為主。這種工藝處理的耐鹽霧測試可達48-72小時，優于市面普通機柜的水平。

In terms of material configuration, the imitation Weitu cabinet has a mature industry practice: the door panel thickness is 2.0mm, the cabinet body (back and side panels) is 1.5mm, and the installation plate is 2.5mm (some manufacturers can choose 3.0mm). High quality cold-rolled steel plates are commonly used as materials, and 304 or 316 stainless steel can be selected for special scenarios such as chemical and outdoor use. The surface treatment adopts electrostatic powder spraying technology, and the pre-treatment includes multiple processes such as degreasing, acid washing, phosphating, passivation, etc. The film thickness can reach 40-60 μ m. The main colors are RAL7032 or RAL7035 weave patterns. The salt spray resistance test of this process can reach 48-72 hours, far exceeding the level of ordinary cabinets on the market.

防護等級方面，仿威圖機柜默認可達IP54（完全防塵+防濺水），部分定制款可達到IP65甚至IP66。細節設計上，柜門與框架接觸處配有發泡橡膠密封圈（厚度3-5mm），配合門板扣手的壓緊結構實現可靠密封；底部進線孔帶橡膠護線套，防止線纜磨損并隔絕粉塵。電氣安全方面，強制要求雙重接地（柜體接地+安裝板獨立接地），接地電阻≤0.1Ω。

In terms of protection level, the imitation Weitu cabinet defaults to IP54 (completely dustproof+splash proof), and some customized models can reach IP65 or even IP66. In terms of detailed design, the cabinet door is equipped with a foam rubber sealing ring (thickness 3-5mm) at the contact point with the frame, which cooperates with the pressing structure of the door panel handle to achieve reliable sealing; The bottom inlet hole is equipped with a rubber protective sleeve to prevent cable wear and isolate dust. In terms of electrical safety, it is mandatory to require dual grounding (cabinet grounding+independent grounding of installation board), with a grounding resistance of ≤ 0.1 Ω.

仿威圖機柜分為ES（五折）、PS（九折）、TS（十六折）三大系列。其中五折和九折型材柜的專利均已過保護期，因此成為仿制的主流方向。模塊化設計使得后期擴容只需增加層板、安裝導軌或側擴展柜即可實現，無需整體更換。正是這種集強度、靈活性、標準化于一體的設計哲學，讓仿威圖機柜在工業控制領域占據了不可替代的地位。

The imitation Weitu cabinet is divided into three series: ES (50% off), PS (10% off), and TS (16% off). The patents for 50% and 90% profile cabinets have both expired, making them the mainstream direction of imitation. Modular design enables later expansion to be achieved by simply adding layer boards, installing guide rails or side expansion cabinets, without the need for overall replacement. It is this design philosophy that integrates strength, flexibility, and standardization that has made the imitation Weitu cabinet occupy an irreplaceable position in the field of industrial control.
