Product descriptions from the supplier

Description

35kV Oil-immersed Grounding transformer Product introduction

35kV Oil-immersed Grounding transformer is commonly used to provide an artificial loaded neutral point for the ungrounded point of the system for system grounding. The neutral point of this product is connected to the arc suppression coil or resistor, and then grounded. A secondary winding with a continuous rated capacity can be used as a power source for the station.

35kV Oil-immersed Grounding transformer Product use

Substations, user distribution stations and other 35kV and below power systems.
