What Is a 35kV Oil Immersed Power Distribution Transformer?

A 35kV Oil Immersed Power Distribution Transformer is a medium-voltage transformer used to convert electrical power from a 35kV distribution network to a lower voltage level required by industrial equipment, commercial buildings, substations, and local power distribution systems.

Unlike dry-type transformers, an oil immersed transformer uses insulating oil as both an insulation medium and a cooling medium. This structure helps improve heat dissipation, electrical insulation performance, overload capability, and long-term operational stability. For industrial plants, infrastructure projects, and outdoor distribution networks, oil immersed transformers are widely selected for their reliability, cost efficiency, and adaptability to demanding operating environments.

Key Features

Low Loss and High Efficiency Design

The transformer is designed with optimized magnetic circuit structure and high-grade silicon steel core to reduce no-load loss and load loss. For users searching for a low loss oil immersed transformer, this design helps improve energy efficiency and reduce long-term electricity costs.

Reliable Oil Insulation and Cooling Performance

High-quality transformer oil provides strong insulation and efficient heat transfer. The oil immersed structure supports stable operation under continuous load conditions and helps maintain safe operating temperatures in industrial and commercial power systems.
