结构特点

Structural features

GCK框架采用压筋(模数E=25mm)组装而成,框架全部构件都经过镀锌处理,零部件的组装全部用自攻锁紧螺钉或高强度六角螺钉紧固,各个零部件的尺寸均实行模数化,从而保证了各零件的通用性、互换性、再按需要加上门、档板、隔板、抽屉、安装梁等零件，组装成品后有美观、牢固、质量好等优点。柜体分成母线室、功能单元室、电缆室三个相互隔离区间，可防止事故扩散和便于带电维修。

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.
