Electric actuators for hydrotechnical constructions on HPP

Electric actuators for hydrotechnical  constructions on HPP efficiency


Area of application:

  • Applied for handling of the following types of paddles:
    - segment
    - flat
    - disc and ball 
  • Replacement of outworn mechanisms and hydraulic drives
  • Mechanical stiffness is similar to hydraulic drive.
  • Electric actuator is flow-operable.
  • Operating rod travel: up to 8 m
  • Rod force: up to 160 tf

Construction peculiarities:

  • For protection of mechanical transmission against flow vibration and “shocking” impact loads active damper is used
  • Hermetic housing and special seals
  • Ceramic rod coating
  • Corrosion-resistant housing coating

Main advantages:

  • Design engineering convenience;
  • Service life: 40 years;
  • Operation at minus temperatures down to -45ºС;
  • Fast commissioning;
  • Minimal maintenance (visual examination: once per year, grease relubrication: once per 10 years);
  • compatibility with any control system;
  • Highest-level reliability;
  • Oil free, environmental friendliness;
  • Capability of carrying multiple static and impact loads;
  • Low power consumption, efficiency 90%.
