Product Description

10kv HengDa Oil Immersed Transformer for Future-Proof Sustainability

Specification

S22Series 10kV Class Two-Winding Non-Excitation Voltage Regulation Distribution Transformer

Oil-filled transformers use liquids for cooling, making them highly suitable for outdoor applications. They are more efficient, have longer service lives, and feature more reliable overload capabilities.Transformer is isolated from the rest of the air, to prevent and slow the deterioration of oil and insulation aging, enhance the operation reliability.
