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.
