Industrial oil-cooled voltage stabilizer installation

Oil-Cooled Voltage Stabilizers

Avani Sales & Service' oil-cooled stabilizers provide robust voltage regulation for heavy industrial applications. Our transformer-based stabilizers use high-grade mineral oil cooling to handle power loads up to 5000kVA while maintaining output voltage within ±1% accuracy, even with input fluctuations from 300V to 480V.

Engineered for continuous operation in India's harsh industrial environments, our oil-cooled stabilizers feature military-grade components and advanced tap-changing technology. The oil cooling system ensures optimal thermal management, allowing 24/7 operation even at 50°C ambient temperatures.

  • ±1% output voltage accuracy
  • Input range: 300V-480V (3-phase)
  • 50kVA to 5000kVA capacity
  • Response time: < 100ms
  • Efficiency up to 98%
  • IP55 protection standard

Industrial-Grade Voltage Stabilization

Avani's oil-cooled stabilizers incorporate microprocessor-controlled tap changing with zero-crossing switching technology. The mineral oil cooling provides superior heat dissipation and component protection, making them ideal for:

  • Steel plants and foundries
  • Cement manufacturing units
  • Heavy engineering workshops
  • Large commercial complexes
  • Hospital infrastructure

Why Choose Avani Oil-Cooled Stabilizers?

Our stabilizers feature CRGO silicon steel cores with Class H insulation, designed for 25+ years of maintenance-free operation. The oil-filled design provides natural cooling and superior protection against dust, moisture, and corrosive industrial atmospheres. Automatic bypass functionality ensures continuous power during maintenance.
