The G-Series

DOWIN G series breakers are very convenient in maintenance using several compatible spares such as front cover, ring bush and through bolt, etc. with other G type breakers.
  • Superior quality alloy steel provides excellent durability and longer life.
  • Box Type breaker was developed to minimize the noise during operation, with use of sound absorbing materials and noise reducing frame design, very useful in the job site of urban area.

Dowin G series provides 4 models from 15 tons to 50 tons class.

  • Operator Friendly Function Enabled
  • Well-Balanced Frame with Fewer Components
  • World Best Quality Control Valve and Piston
  • Lower Cost to Maintain with a Good Durability
  • Superior Quality Alloy Steel for Main Power Cell Parts
  • DW 15G

    DW 15G

    • Incorporates a moulded frame.
    • 65mm tension bolt.
    • Less maintenance as compared to other breakers in the market.
    • Nine support ribs which results in superior structural strength.
    • Comparitively more cost effective as opposed to the T-Series.
