Oil-immersed transformers equipped with front and rear protection boxes that facilitate safe and accessible connections; their robust construction and the use of dielectric oil guarantee efficient cooling and optimal insulation in demanding environments. They are ideal for withstanding extreme conditions, such as high temperatures, humidity, and dust, ensuring high reliability, durability, and protection of critical electrical equipment. They are also equipped with special accessories for monitoring and protection, such as thermometers to measure oil temperature, oil level indicators, pressure relief valves, and Buchholz relays for detecting internal faults. These devices guarantee safe and efficient operation, allowing continuous monitoring of equipment conditions.
