結構特點

Structural features

GCK框架采用壓筋(模數E=25mm)組裝而成,框架全部構件都經過鍍鋅處理,零部件的組裝全部用自攻鎖緊螺釘或高強度六角螺釘緊固,各個零部件的尺寸均實行模數化,從而保證了各零件的通用性、互換性、再按需要加上門、檔板、隔板、抽屜、安裝梁等零件，組裝成品后有美觀、牢固、質量好等優點。柜體分成母線室、功能單元室、電纜室三個相互隔離區間，可防止事故擴散和便于帶電維修。

The GCK frame is assembled with compression bars (modulus E = 25mm), all components of the frame are galvanized, all parts are assembled with self tapping locking screws or high-strength hexagon screws, and the dimensions of all parts are modular, so as to ensure the universality and interchangeability of all parts, and then add door, baffle, partition, drawer, mounting beam and other parts as needed, After assembling the finished product, it has the advantages of beauty, firmness and good quality. The cabinet is divided into three mutually isolated sections: bus room, functional unit room and cable room, which can prevent the spread of accidents and facilitate live maintenance.
