Key Product Features

Cable Management Excellence
Equipped with cable boxes or compartments, our transformers facilitate easy and secure cable termination on both High Voltage (HV) and Low Voltage (LV) bushing terminals. This design promotes problem-free maintenance and minimizes downtime.
Customizable Arrangements
Choose from three pre-engineered arrangements, each designed to align with your specific requirements and industry standards: - Cable boxes with HV and LV terminals positioned either at opposite sides of the tank or on the lid. - Compartments featuring HV and LV terminals on the same side of the tank conforming to ANSI / IEEE standards. - The HV side offers flexible dead or live front configurations, catering to loop or radial feed setups.
Innovative Tank Design
UTEC’s transformers are oil-immersed in a hermetically sealed tank. The tank's ingenious construction accommodates oil expansion during loading through corrugated steel sheets. For added versatility, choose from sealed tanks with detachable radiators for nitrogen-filled gas space or the free-breathing type with an oil conservator tailored to your unique specifications.

Proven Performance

Reliable Operation

Backed by extensive industry expertise, our transformers offer a proven track record of reliability and longevity. Count on uninterrupted power supply that reduces downtime and enhances operational efficiency.

Precision Engineering

Crafted in compliance with ANSI / IEEE standards, our transformers exemplify precision engineering, ensuring seamless integration into existing power systems.

Efficient Cooling

Our transformer's innovative radiator designs ensure efficient cooling, maintaining optimal operating temperatures even under heavy loads. This design safeguards the longevity of your equipment and minimizes maintenance requirements.

Safety First

Transformers are hermetically sealed to prevent oil leaks. Options for both sealed and free-breathing designs are available. Free-breathing transformers offer an oil conservator system, maintaining internal pressure and safeguarding against overpressure situations.
