Product Description
Product Description
Description about Three Phase Oil Immersed Power Transformer
Oil-immersed power transformers are critical components in electrical power systems, widely used for voltage conversion, energy transmission, and distribution across grids. These transformers employ mineral oil or synthetic ester fluid as both an insulating and cooling medium, enabling efficient operation under high-voltage conditions.
According to the customer's project requirements, we provide customized transformer services.
According to the different insulation materials, Pearl Electric can provide mineral oil distribution transformers without PCB, environmentally friendly FR3 vegetable oil immersed power transformers, and NINAS oil power transformers.
According to the different requirements of iron core materials, Pearl Electric can provide oil-immersed transformers with silicon steel sheet iron cores and oil immersed transformers with amorphous alloy iron cores. Among them, amorphous alloy oil immersed transformers are ultra-high efficiency transformers with losses only 20-30% of silicon steel sheet transformers, which are very suitable for projects with high energy efficiency requirements.
