In 2021, Huawei established contact with our company and purchased equipment from a company in Beijing due to our high prices. After one year, it failed to pass the acceptance inspection.

In November 2022, it is necessary to re purchase this equipment. After two months of negotiation comparison.Finally, we signed a technical agreement for the DC breakdown strength measuring instrument (0-30kV DC breakdown voltage test) with our company, and issued a third-party metrological verification certificate before leaving the factory.

The main advantage of this device is its ability to achieveDC output voltage fluctuation coefficient:<2.5%. Sampling output configuration capacitor: 100pF/50kV. Measurement error: ≤ 1% F.S.

This device passed the acceptance inspection on December 14, 2022.
