Transformers that use oil as an insulator, like our oil-immersed transformers, represent the state-of-the-art in design and construction, and have undeniable advantages and excellent application capabilities in both developing and advanced countries. Our engineers design these transformers so that they are easily adaptable to the various energy systems around the world. The construction of these transformers is such that they are able to function in an oil-immersed environment with their smoldering, boiling, and crashing oil. The recently developed methods of Smart Dust technology, other sensor technologies, and AI have made available the instantaneous monitoring of the unit and all its components and systems. These methods make available, and have increased the accuracy of, failure prevision and removal of downtime failure, as well as the optimization of the operational costs of the unit, and below-the-surface/uknown limit, away from the operational ignored costs. Reliability and versatility of these transformers make them applicable in all areas of: industrial plants, commercial buildings, renewable energy solutions and smart cities. Custom solutions is our engineering-guided philosophy, resulting in safe energy, minimized operational risks and enhanced overall performance.
