在(zai)工業控制柜領域，仿威(wei)圖機(ji)柜幾乎成了(le)一(yi)個(ge)品類(lei)的(de)代名(ming)詞。其核心(xin)魅(mei)力在(zai)于(yu)以九折型材為骨架的(de)框(kuang)架結構——一(yi)種將(jiang)力學性能、模塊化設(she)計(ji)和制造(zao)成本平衡到(dao)出彩的(de)工程方(fang)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(tong)過(guo)輥壓線經九次(ci)折彎成型的一種(zhong)特殊(shu)型材。這(zhe)種(zhong)型材作為機柜(ju)(ju)的“骨架(jia)”，通(tong)過(guo)優(you)良專用三(san)通(tong)焊接成整體框(kuang)(kuang)架(jia)。框(kuang)(kuang)架(jia)結構的好處是多維度(du)的：頂(ding)板、底板、側板、門板、裝(zhuang)置板等(deng)部(bu)件通(tong)過(guo)螺絲固定在框(kuang)(kuang)架(jia)上(shang)，既提(ti)高了機柜(ju)(ju)的剛度(du)和強(qiang)度(du)，又實(shi)現了面板的可拆卸性。單柜(ju)(ju)承(cheng)重普遍可達(da)500-1500KG，部(bu)分設計(ji)甚至可達(da)2000KG，足以應對變頻器(qi)(qi)、重型斷路(lu)器(qi)(qi)等(deng)各種(zhong)重型電氣設備的安裝(zhuang)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(cai)(cai)料配置方(fang)面(mian)，仿(fang)威圖機柜有著(zhu)成(cheng)熟的(de)行業慣例：門板(ban)厚度2.0mm，柜體（背板(ban)、側板(ban)）1.5mm，安裝板(ban)2.5mm（部分廠家可選(xuan)3.0mm）。材(cai)(cai)質多(duo)選(xuan)用(yong)優良冷軋鋼(gang)板(ban)，特殊場景（如化(hua)(hua)工、戶外）可選(xuan)用(yong)304或(huo)316不銹鋼(gang)。表面(mian)處(chu)理(li)(li)采(cai)用(yong)靜電(dian)噴粉工藝，前處(chu)理(li)(li)包(bao)含脫(tuo)脂、酸(suan)洗、磷化(hua)(hua)、鈍化(hua)(hua)等(deng)多(duo)道工序，漆膜(mo)厚度可達(da)40-60μm。顏色(se)以RAL7032或(huo)RAL7035兩種(zhong)織紋為主。這種(zhong)工藝處(chu)理(li)(li)的(de)耐鹽霧測試可達(da)48-72小時(shi)，優于市面(mian)普通機柜的(de)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(hu)等級方面，仿(fang)威(wei)圖機柜(ju)(ju)默認可(ke)達IP54（完全防塵+防濺水），部分定制(zhi)款可(ke)達到IP65甚(shen)至IP66。細節(jie)設計上，柜(ju)(ju)門與框(kuang)架接(jie)(jie)(jie)觸處配有發泡橡膠(jiao)密封圈（厚度3-5mm），配合門板扣(kou)手(shou)的壓緊(jin)結構(gou)實現可(ke)靠密封；底部進(jin)線(xian)孔帶(dai)橡膠(jiao)護(hu)線(xian)套(tao)，防止(zhi)線(xian)纜磨損并隔絕粉塵。電氣安全方面，強(qiang)制(zhi)要(yao)求(qiu)雙重接(jie)(jie)(jie)地(di)（柜(ju)(ju)體接(jie)(jie)(jie)地(di)+安裝板獨(du)立(li)接(jie)(jie)(jie)地(di)），接(jie)(jie)(jie)地(di)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(fang)(fang)威(wei)圖機(ji)(ji)柜(ju)(ju)分為ES（五折）、PS（九折）、TS（十(shi)六折）三大(da)系列。其中五折和(he)九折型(xing)材柜(ju)(ju)的(de)專利均已(yi)過保(bao)護(hu)期，因此成為仿(fang)(fang)制的(de)主流方向。模塊化設計使得后期擴容(rong)只需(xu)增加層板、安裝(zhuang)導軌或側擴展柜(ju)(ju)即(ji)可實現(xian)，無(wu)需(xu)整體更換(huan)。正(zheng)是(shi)這種(zhong)集強(qiang)度、靈活性、標(biao)準化于一體的(de)設計哲學，讓仿(fang)(fang)威(wei)圖機(ji)(ji)柜(ju)(ju)在工(gong)業控制領域(yu)占據了不(bu)可替代的(de)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.
