CDYH-W Series

CDYH-W Series

Description

CDYH-W impulse voltage generator is designed for outdoor applications of high voltage level, high capacity, high load requirements and wind-proof, rain-proof and anti-UV properties for extreme ambient conditions. It is mainly used to test the ability of outdoor HV apparatus withstanding voltage peaks (medium and high voltage transformer, switch, cable, inductor, insulator etc). It is designed for applicationsof research and routine test.
