Heavy-Duty Voltage Stabilizers for Industrial and Commercial Applications


At Indus Power Industries Pvt. Ltd., we know that stable and reliable voltage is the backbone of smooth operations for industries, institutions, and businesses. Voltage fluctuations not only reduce the efficiency of your equipment but can also lead to downtime, costly breakdowns, or permanent damage.

To address these challenges, we bring you our Oil Cooled Servo Controlled Voltage Stabilizers – engineered for rugged performance, high energy efficiency, and reliable voltage regulation. Built with transformer oil cooling technology, these stabilizers are ideal for heavy-duty, high-capacity applications, ensuring uninterrupted operations even in the harshest environments.

Whether you need a 100 kVA oil cooled stabilizer for industrial machinery or a 1000 kVA servo stabilizer for large-scale operations, Indus Power offers customized, durable, and efficient solutions.

What is an Oil Cooled Servo Voltage Stabilizer?

An Oil Cooled Servo Voltage Stabilizer is a servo motor-controlled automatic voltage stabilizer that ensures stable output voltage, protecting your equipment from voltage variations. Unlike traditional stabilizers, it provides continuous and precise correction rather than step-by-step regulation.

The oil cooling system uses high-grade transformer oil for thermal management, making it suitable for heavy-duty operations where natural air cooling is not sufficient. This design ensures:

  • Long-term durability and stability
  • Ability to handle high loads
  • Rugged performance in demanding industrial conditions
  • Better heat dissipation compared to air cooled models

Oil cooled servo stabilizers are available in single-phase and three-phase designs, with capacities ranging from 10 kVA to 1000 kVA and above.
