Dry Type Transformers have become a preferred solution in many industrial environments due to their safety, reliability, and environmental benefits. Unlike oil-filled transformers, they operate without liquid insulation, making them ideal for facilities that prioritize fire safety, low maintenance, and clean operation.
At ETAC, our Dry Type Transformers are designed with precision and built to perform in the most demanding environments. Each unit is engineered in compliance with CSA C9 standards, ensuring long-term reliability, safety, and efficiency. In this article, we highlight the five key Advantages of Dry Type Transformers that make them a smart and dependable choice for industrial applications.
Thanks to their oil-free construction, dry type transformers eliminate the risk of fire or environmental contamination. This makes them ideal for indoor use, underground facilities, and spaces where personnel and equipment are in proximity. Their self-extinguishing insulation system and robust design provide an added layer of protection.
Without oil to monitor, contain, or replace, dry type transformers require significantly less maintenance. At ETAC, we use vacuum pressure impregnation (VPI) or cast resin technologies to ensure thermal and mechanical durability.
Our transformers are built with high-grade silicon-steel cores and optimized coil designs to reduce losses and improve efficiency. Because there’s no oil, there are no leaks, spills, or hazardous waste supporting clean, sustainable operations and reducing the need for additional containment infrastructure. As a result, facilities benefit from lower operational costs and cleaner, safer performance.
ETAC Dry Type Transformers are used across a wide range of industries including mining, manufacturing, utilities, commercial buildings, and renewable energy. With voltage ranges up to 35 kV and configurations available for both indoor and outdoor use (NEMA 1, 3R, 4X enclosures), they are adaptable to virtually any installation requirement.
We offer flexible design options, including aluminum or copper windings, optional thermal sensors, forced-air cooling systems, and customizable terminal arrangements. Lead times are typically under 16 weeks, and each unit is backed by a warranty of 12 months(can be extended to 36 months under request), ensuring fast delivery and long-term performance.
This combination of customization and quick delivery ensures clients receive transformers that meet their exact operational needs.
