electrical equipment

Hydropol Group is able to deliver generators, substations, automation and monitoring systems and other power plant electrical equipment, specially adjusted for exact needs of the site and client. It matches all individual requirements in the fields of construction materials, efficiency, standards, environmental restrictions, positioning, etc. The equipment is being outsourced and "tailor-made" packaged with our relevant technical, quality and commercial guarantees:

  • Asynchronous generators 200 - 600 kW, voltage 0,4 kV, speed 600 - 1 000 rpm. 
  • Synchronous generators 300 kVA - 20 MVA, voltage levels 0,4 kV, 6,3 kV a 10,5 kV, speed 150 - 1 000 rpm. Larger generators including mechanical brakes. Smaller air-cooled generators, larger water-cooled generators. 
  • Static or rotary excitation and AVR of generators, for larger generators with possibility of electric braking. HW and SW including peripherals, interfaces, binary and analogue inputs and outputs, all integrated into panels. 
  • Control systems of hydro power plants, HW and SW including peripherals, interfaces, binary and analogue inputs and outputs, all integrated into panels. 
  • Electrical part of turbine governors, HW and SW including peripherals, interfaces, binary and analogue inputs and outputs, all integrated into panels. 
  • Control systems of hydro power plants, (SCADA) HW and SW including peripherals, interfaces, binary and analogue inputs and outputs, all integrated into panels. 
  • Electrical protections of generators, HW and SW, calculations. 
  • Switchboards 400 V AC. 
  • Switchboards 24, 110 a 220 V  DC including accumulator rooms 
  • Switchboards 6,3 kV, 22 kV a 35 kV, vault-type or cubicle-type (circuit breakes, isolator switches, disconnectors, metering current and voltage transformers, fuses, surge voltage protectors, lightning arresters, busbars, bushings, support insulator, safety and protection tools for manipulations …). 
  • Electrical protections of MV and HV substations, HW and SW, calculations. 
  • Uniterrupted power sources (UPS). 
  • Control, communication and power cables, fibre cables. 
  • Monitoring, fire protection and security systems. 
  • Power step-up transformers 63 kVA - 20 MVA. Transmissions 0,4/6,3 kV, 0,4/22 kV, 0,4/35 kV, 6,3/22 kV, 6,3/35 kV, 10,5/22 kV, 10,5/35 kV. Dry-type and oil-type transformers.
