Overview

HTXZ-1000KVA/500kV variable frequency series resonance is mainly designed and manufactured for the AC withstand voltage test of all electrical main equipment such as 10-500kV substations and lines. The reactor adopts multiple separate designs, which can meet the requirements of equipment testing conditions for high voltage and low current, as well as the requirements of AC withstand voltage testing for low voltage and high current. It can meet the needs of high voltage testing departments and power installation and maintenance engineering units at the local, municipal, and county levels for easy mobility on site.
