產品特點 Product feature

■設計緊湊；以較小的空間能容納較多的功能單元。

■結構通用性強，組裝靈活：以25mm為模數的C型型材能滿足各種結構型式、防護等級及使 用環境的要求。

■采用標準模塊設計：分別可組成保護、操作、轉換、控制、調節、測定、指示等標準單元，用 戶可根據需要任意選用組裝。以200余種組裝件可以組成不同方案的相架結構和抽屜單元。 ■安全性：大量采用高強度阻燃型工程塑料組件，有效加強防護安全性能。

■技術性能高：主要參數達到當代國際技術水平。

■壓縮場地；三化程度高，可大大壓縮儲存和運輸預制件的場地。

■裝配方便：不需要特殊復雜工具。

The switchgear owns good characteristics asfollowing:

■Com pact,space saving desigh.

■High generalization in structure design and flexi bil ity i nmake-u p. The C profiles of sheet steel with 25mm modularinterval can meet the needs of all kinds of structural types,protection degrees, operating and enviromental conditions.

■Adoption of standard module design. They can make up a variety of standard units for protection, operation,switching,controlling, regulating, measuring and indication. The user may choose at option the relevant standard unit for assemble according to requirement. Up to more than 200of structure parts and funcational modules make it possible to make up a variety of structure frames and drawer units for different schematic requirements.

■Adoption of large number of the high strength flame-resisting plastic modularsand functional partition plates are effective to strengthen the performance of safety protection.

■High technical characteristics, main parameters reach a fairly high international advanced level.

■Reduction in space requirement for storing and transporting pre-fabricated parts thanks to the high degreeof seriation, standardization and generalization of the structure.

■Easy assembly, no special tools are necessary.
