Product Description

2000kVA Step Down Oil Immersed Transformer Premium Copper Wire Electrical Transformers with Factory Price

Specification

S11Series 10kV Class Three-Phase 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.
