The StromerPower 35kVA Three Phase Alternator (STRO-35K) is a commercial-grade, three-phase low-voltage AC alternator engineered within a strict ISO 9001 quality assurance environment to deliver uncompromising reliability. Designed as a premium component for stationary diesel generator sets, mobile power plants, and industrial equipment, this 4-pole brushless alternator features high efficiency, low reactances, and exceptional motor-starting capacity under heavy starting loads.

  • Dual-Rating Performance: Delivers 31.8kVA Prime power and up to 35kVA Standby power output at a stable 50Hz frequency (PF = 0.8).
  • Advanced Voltage Regulation: Features the industry-standard SX460 AVR model maintaining a tight +/- 1% voltage regulation to shield sensitive equipment from fluctuations.
  • Clean Power Winding: Implements a 2/3 pitch stator winding layout that cleanly suppresses lower-order harmonic distortion, keeping Total Harmonic Distortion (THD) under 5%.
  • Rugged Mechanical Interface: Built with a resilient single-bearing configuration optimised for native SAE housing flange and clutch flex plate alignment setups.
  • Industrial Grade Protection: Outfitted with an IP23 weather-protective enclosure, Class H insulation, robust steel base, and dynamically balanced rotors compliant with ISO 1940 vibration specifications.
SUPERIOR QUALITY AND PERFORMANCE

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

GENERAL SPECIFICATIONS

StomerPower 35kVA Alternator

Strengthen your company's operational standby capability with the StromerPower 35kVA Three Phase Alternator (Model: STRO-35K). Developed to support critical multi-phase commercial operations and production setups, this heavy-duty brushless synchronous component acts as a high-performance power core for manufacturing machinery, industrial facilities, and large-scale agricultural infrastructure. Operating at a balanced 1500rpm threshold, its 4-pole self-excited architecture manages high inductive starting currents smoothly, protecting internal systems from premature heat degradation.

Specifically tailored to deliver balanced, stable power across all three lines, the STRO-35K provides a highly efficient 31.8kVA prime output rating. Integrating this genuine StromerPower component into your generator design ensures that heavy workshops, ducted cooling networks, distribution panels, and high-torque electric motors run smoothly through long grid outages.

Precision Three-Phase Regulation and Advanced Waveform Control

Featuring advanced structural ventilation paths and superior heavy-load balance, this unit interfaces cleanly with modern engine blocks without causing alignment errors or added mechanical wear. The rigid frame assembly and high-purity copper stator layouts ensure a highly dependable, long-term investment for any enterprise focused on maximising uptime.

StromerPower 35kVA Alternator Key Features

  • Heavy-Duty Phase Delivery: Supplying a reliable 31.8kVA prime capacity, this alternator seamlessly balances large multi-phase loads across commercial and light industrial operations.
  • Low Vibrational Signature: Built with exceptional internal balancing and tight production tolerances, the unit minimises acoustic echoes inside custom generator enclosures.
  • Optimised Fuel Conversion: Crafted with premium copper windings that lower internal impedance, directly improving engine fuel economy numbers under continuous factory loads.
  • Resilient Structural Build: The structural steel base frame handles rigorous on-site conditions effortlessly while maintaining a compact footprint for easy plant positioning.
  • Integrated Automatic Regulation: Outfitted with a standard Automatic Voltage Regulator (AVR) module to control line voltage fluctuations and shield fine control machinery from spikes.
  • Advanced Thermal Insulation: Uses high-grade H-class insulation material alongside an IP23 protective housing to keep processing lines moving in challenging, high-temperature environments.
  • Accessible Junction Layout: An oversized, top-mounted terminal enclosure gives technicians clear access for quick input wiring, diagnostics, or adjustment steps.
  • Certified Sine Quality: Supported by StromerPower's established field reputation, this low-reactance alternator limits total harmonic distortion to deliver an exceptionally clean power wave.
