Product Description

VLF 35kV Cable Withstand Voltage Very Low Frequency Tester

Product Description

VLF 35kV Cable Withstand Voltage Very Low Frequency Tester is designed and manufactured for very low frequency withstand voltage test for electrical equipment.

Very low frequency withstand voltage test is essentially an alternative to the power frequency withstand voltage test. It is much smaller, lighter, and more portable than a power frequency withstand voltage tester. It has been proved at home and abroad that 0.1Hz ultra-low frequency withstand voltage test can replace power frequency withstand voltage test.

VLF 35kV Cable Withstand Voltage Very Low Frequency Tester can be applied for 10kV, 35kV, 300MW thermal power machine, 10kV, 35kV power transformer, and other electrical equipment.
