Urja Techniques has been one of the eminent name in the sector of manufacturing transformers.Further, to quality production, we also have earned a reputation in the industry as an ideal supplier and exporter of transformers and associated products. We are well known for the production of solar converter duty transformers and a diverse array of other transformer types including earthing, furnace, reactor transformers, compact sub-stations and dry type transformers. Urja Techniques has been in the forefront as far as adherence to recognized standards such as IS, IEC, and ANSI is concerned. As a team of successful and established technocrats, we strive to achieve better techniques and aggressively pursue opportunities related to exports of our varied products range.


A hermetically sealed transformer is a type of transformer that has its windings and core completely sealed in a housing filled with insulating medium such as oil, to provide cooling and insulation. The term "hermetically sealed" refers to the fact that the casing of the transformer is airtight, meaning it does not breathe in or out, which keeps moisture and atmospheric contaminants away from the internal components of the transformer. These transformers are maintenance free and much suited for utilization in outdoor environments. Fabricated for substantial usage at chemical plants, oil and gas terminals, these type of transformers are equipped with devices that measure heat related volume variations.

Hermetically Sealed Transformers offered by Urja Techniques (India) Pvt Ltd is an advanced solution, designed to meet the demanding requirements of various industrial applications. These transformers are built with precision and adhere to the highest standards of quality and performance.


  • Superior Insulation: The transformers are equipped with high-quality insulation materials that ensure optimal performance and minimize the risk of breakdowns or malfunctions.
  • Hermetic Sealing: The transformers are sealed to prevent the ingress of moisture, dust or other contaminants. This hermetic sealing enhances the lifespan of the transformers and ensures their security in challenging environments.
  • Compact Design: These transformers are built with a compact and space saving design, making them ideal for installations with limited space availability.
  • Energy Efficiency: Hermetically Sealed Transformers are designed to minimize energy losses, resulting in improved overall efficiency and reduced operational costs.


  • Enhanced Reliability: The hermetic sealing of these transformers provides excellent protection against external factors, ensuring reliable and uninterrupted performance even in harsh operating conditions.
  • Longer Lifespan: The superior insulation and hermetic sealing contribute to the extended lifespan of the transformers, reducing the need for frequent maintenance and replacements.
  • Improved Safety: The sealed construction of these transformers eliminates the risk of internal faults or leaks, enhancing operational safety and mitigating potential risks.
  • Space Optimization: The compact design of hermetically sealed transformers enables efficient utilization of available space, making them an ideal choice for installations with limited footprint.
