  • Introduction

     


    Our main products are brushless excitation rectifier assemblies used for 10~1350MW turbine generator. The brushless excitation technology can be widely used for generator and motor, especially large generator due to the integration of rectification components and exciter rotor, they are synchronous revolution and remove the commutator, slip-ring and carbon brush, which are the unsurpassable advantages of brush excitation. Rotating rectifier excitation assembly is comprised of rectifier, capacitor, fuse, heat sink, conduct piece, insulation component, fastener and other main devices and components. It has the advantages of small size, enhanced functions, high technology content.

     

    Features

     


      High reliability, no required maintenance for slip-ring and carbon brush.
      Long insulation life, no pollution on generator field coil caused by carbon powder and copper powder.

      Suitable for working in harsh environment, no friction spark. - See more at:
