An electrical transformer that uses oil as an insulating and cooling medium is known as an oil-filled distribution transformer. To step down the voltage from high voltage levels to lower voltage levels suited for usage in residences, commercial buildings, and other low voltage applications, it is frequently employed in electrical power distribution systems.
The transformer’s core, which is commonly formed of laminated steel sheets, serves as a conduit for magnetic flux. Power is more effectively transferred from the primary winding to the secondary winding thanks to it. The transformer has primary and secondary winding sets. While the secondary winding produces the lower voltage output for distribution, the primary winding receives the high voltage input from the power grid.
The transformer converts the high voltage electricity from the power grid to lower voltages suited for local distribution while it is in operation. This makes it possible for electricity to be safely delivered to consumers at the right voltage levels across power lines. In electricity distribution networks, oil-filled distribution transformers are renowned for their dependability and effectiveness.
To maintain good operation and lifespan, they need routine maintenance, which includes keeping an eye on the oil. Oil-filled transformers are still widely used in many electrical grids across the world, while newer transformer technologies, including dry-type transformers, may occasionally be employed as a substitute where environmental or safety issues exist.
The Europe oil filled distribution transformer market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Innovative oil-free and plug-and-play traction transformers are now available from Hitachi Energy. The dry-type traction transformer for RESIBLOC Rail with integrated cooling system is intended to improve energy efficiency while lowering CO2 emissions and overall operating expenses. RESIBLOC Rail, a novel oil-free traction transformer with an integrated cooling system and voltages up to 25 kilovolts (kV), has been introduced by Hitachi Energy.
A ground-breaking technological advancement for dry-type on-board traction transformer is this plug-and-play solution. Hitachi Energy considerably minimizes installation complexity for train makers while maintaining the advantages of dry-type transformers by including an effective cooling system. This traction transformer has a factory-installed cooling system that is integrated with the traction transformer’s design, giving the customer a plug-and-play dry-type traction transformer solution that has never been possible before.
