DC high voltage tester

main feature:
1. Adopt high-frequency voltage doubler circuit, apply PWM pulse width modulation technology and high-power IGBT devices.
2. Using large voltage feedback, high output voltage stability, and small ripple factor ≤ 1%.
3. Full-scale smooth voltage regulation, fine voltage regulation, adjustment accuracy ≤ 0.5%, stability ≤ 1%, voltage and current error 1% (reading ±0.2kV, current error ±1 word.
4. The booster potentiometer has zero boost.
5. With 75% UDC1mA function button, it is convenient for zinc oxide surge arrester test, accuracy 1% reading ±1%.
6. The overvoltage protection adopts the code setting, which is clear at a glance, and the error is ±1%.
7. The double pressure adopts new materials, which are light and strong.
8. The surface is coated with special insulating materials, with good electrical performance and strong moisture resistance.
9. Folding support feet, large diameter area, good stability.

Founded in 2003, FANKE is the domestic leader specializing in designing and manufacturing HV test, measurement and overhaul equipments. In 2003, Wuhan HIGHVOLT Co.,Ltd is established as our subsidiary. We provide a diversity of complete testing solutions and one-stop service for electric power companies, electric research institutions and electric equipments manufacture companies.
Located in Guannan Science and Technology Industrial park-- the Optical Valley of China, we cover an area of 12,000 square meters used for workshop and offices.With the registered capital of 16,000,000 yuan, our annual sales volume reaches 70,000,000 yuan. As a sub-measurement unit of Wuhan city, we develop us as a comprehensive high-tech enterprise integrating research, development, production, installation, commission, sales and service consultancy.

Good networking keeps us stay advantageous and innovative in the market. Relied on the wide cooperation with institutions of higher learning in Wuhan, we establish a HV research center supported by professional HV engineers and specialists from Wuhan High Voltage Research Institute of State Grid, Institute of Water Conservancy and Hydroelectric Power of Huazhong University of Science &Technology and Wuhan University.

Our management team is composed of professional administrators with rich experience in modern business and project management and technical personnel specializing in HV, power transmission, transformation and automation. Until now, we employ 75 stable workers, 65% of whom have bachelor degree and some of the rest are advanced engineers and professional experts with Doctor degree.

We hold numerous intellectual property rights, utility model and invention patents for products, such as hydraulic integrated high voltage withstand test system, series resonant test trail, ultra high voltage AC/DC voltage withstand test equipment, power frequency PD free voltage withstand test equipment and other electric power maintenance equipments as well as other tailor-made products.
Our products have been applied for onsite handover, preventive maintenance and quality inspection test. We have customers all around the country, including stated-owned institutions and large-scaled enterprises in sections of railway, oil industry and chemical engineering. Some products have been exported to overseas markets, including USA, Mid-east, Korea, India and Vietnam, ect.

With a vision to win-win result, We will continue to focus on customer needs and rely on technical innovation, striving to become the top-ranking provider for electric testing and measurement equipments and EPC engineering service.
