We offer industry leading 24 month / 1,000 hour warranties on our engines and diesel generators.

The StromerPower 220kVA Three Phase Alternator (STRO-220SD) provides a high capacity power core for heavy duty generator builds and commercial replacements. Assembled under a strict ISO 9001 quality assurance scheme, this 4 pole brushless unit gives engine builders a dependable baseline to manage high industrial starting loads without forcing sudden sags across facility distribution lines.

  • Power capacity: Supplies a reliable 200kVA prime rating for continuous application and up to 220kVA standby power at a stable 50Hz.
  • Responsive AVR control: An integrated automatic voltage regulator manages line fluctuations to protect electronics.
  • Low reactance: Employs high purity copper windings to minimise impedance losses, maintaining clean power wave while improving engine fuel efficiency.
  • Rugged core housing: Built on a thick structural steel base with Class H thermal insulation and an IP23 weather protective shell to withstand harsh, humid or dusty environments.

We offer delivery across Sub-Saharan Africa at the best prices.

SUPERIOR QUALITY AND PERFORMANCE

StromerPower sets new global standards in all aspects, from design, manufacturing, material selection, production and testing equipment, tooling, and quality control.

GENERAL SPECIFICATIONS

StomerPower 220kVA Alternator

The StromerPower STRO-220SD is a high output three phase alternator for heavy duty generator builds as well as commercial and industrial applications. Built under a strict ISO 9001 quality assurance system, this 4 pole brushless unit provides engineers with a robust platform that handles heavy  load transfers without dropping line voltage. It operates at a steady 1500rpm to keep operations running smoothly through grid outages.

StromerPower 220kVA (STRO-220SD) Alternator Features

  • Power capacity: Provides 200kVA prime power and 220kVA standby output for backup operations (50Hz at 0.8 power factor).
  • Line balancing control: The factory installed automatic voltage regulator manages variations to steady outbound currents and protect equipment.
  • Copper core efficiency: Built with premium insulated copper windings that lower impedance means less waste heat and better engine fuel economy.
  • Vibration management: A dynamically balanced rotor limits operational resonance to help maintain low noise.
  • Rigid core chassis: Features a robust steel mounting base frame, an IP23 weather protective shell and Class H insulation.
  • Oversized terminal hub: The terminal box allows easy access for quick terminations, phase balancing and routine maintenance.
