Variable Voltage Oil Transformer

DAYA electrical, a prominent manufacturer and supplier of Variable Voltage Oil Transformers in China, has decades of expertise in high-voltage equipment. Oil-immersed transformers are a crucial component in power distribution networks and substations, where their cores and coils are submerged in oil for both cooling and insulation purposes. This oil circulates through internal piping, facilitated by convection, to effectively dissipate heat. Our products offer excellent value for money and have gained significant market share in South America, the Middle East, Africa, and Southeast Asia. We pride ourselves in meeting the needs of power users and design units, providing solutions that align with national conditions, possess high technical performance indicators, and are adaptable to the evolving electricity market. We eagerly anticipate the opportunity to become your trusted long-term partner in China.

Product Description

DAYA Variable Voltage Oil Transformer Details

Our Variable Voltage Oil Transformers encompass a diverse range of distribution, medium, power, and generator transformers, spanning from 40 MVA to 132 kV. They are available in a wide spectrum of ratings and capacities, from 50 kVA to over 2500 kVA (equivalent to 2.5 MVA).

Due to their mechanism and fluid use, Variable Voltage Oil Transformers are designed primarily for outdoor installation, as they pose specific health and safety risks. Despite this, they occupy less space compared to dry-type transformers of similar capacity. Conversely, dry-type transformers offer versatility, being suitable for both indoor and outdoor installations.
