Feature of Box Type Substation

  • Compact design: Contain more function units with less space.

  • Strong versatility for structure, flexible assembly. C type bar section of 25mm modulus can meet the demands of various structures and types, protection grades and operating environments.

  • Adopt standard module design, can be combined into protection, operation, transfer, control, regulation, measurement, indication, etc such standard units. Users can choose assembly according to requirements at will. A cabinet structure and drawer unit can be formed with more than 200 components.

  • Fine security: Adopt high-strength antifoaming type engineering plastic pack in large quantities to effectively enhance the protective safety performance.

  • High technical performance: Main parameters reach the advanced level at home.
