MOEORW-WVF30kV VLF HV Generator
The MOEORW-WVF series 0.1Hz integrated VLF HV Generator is suitable for insulation withstand voltage tests of capacitive electrical equipment of 35kV and below. It complies with national standards, is easy to operate, safe and reliable, and has excellent adaptability for outdoor operations.
Product Introduction
Our company's new generation of 0.1Hz VLF High-Voltage Generator utilizes the latest power electronic components and ARM7 microcontroller technology, further reducing the size and weight of the equipment. It features user-friendly operation, more stable performance, and overcomes the shortcomings of the first-generation mechanical voltage booster, such as short lifespan, high failure rate, and large size. Years of practical experience and extensive user feedback have demonstrated that this series of ultra-low frequency high voltage technologies is leading nationwide and offers excellent value for money!
