Product Description

VLF 32kV Cable Ultra Low Frequency High Withstand Voltage Hipot Testing Instrument

Product Description

VLF 32kV Cable Ultra Low Frequency High Withstand Voltage Hipot Testing Instrument is designed and manufactured for electrical equipment very low frequency withstand voltage test.

Very low frequency withstand voltage test is essentially an alternative of power frequency withstand voltage test. It is much smaller, lighter and portable than power frequency withstand voltage tester. It is proved home and abroad that 0.1Hz ultra-low frequency withstand voltage test can replace power frequency withstand voltage test.

VLF 32kV Cable Ultra Low Frequency High Withstand Voltage Hipot Testing Instrument can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer and other electrical equipment
