HINDUSTAN POWER is a well-known manufacturer and supplier of servo stabilizers in Hyderabad, India. Our oil-cooled servo voltage stabilizers are popular among customers, and we cater to clients across India and abroad. Our products are manufactured with high-quality standards, which make them reliable, trustworthy, and safe to use. We use oil with specific characteristics, which helps the stabilizer function optimally. Our capillary tube systems ensure even oil circulation throughout the unit.
Our three-phase oil-cooled servo stabilizers ensure trouble-free voltage regulation, which helps in power saving and management. We offer customized solutions with capacities ranging up to 500kVA, designed for indoor and outdoor applications. Our three-phase oil-cooled servo-controlled voltage stabilizers are built with standardized servo motors, which are designed to vibrate the oil in the fins. Our units are capable of withstanding a capacity range of up to 500kVA, and we customize them according to the specific needs of our customers for indoor and outdoor usage.
