Product Introduction
The power‑frequency withstand voltage test device is an essential high‑voltage test equipment for power systems, industrial & mining enterprises and scientific research institutions. It is composed of two core modules: control unit and boost unit.
SXTC series control boxes & consoles are special supporting control equipment for light‑duty test transformers. Featuring convenient maintenance, stable & reliable performance, beautiful appearance and compact rugged structure, they are easy to transport for on‑site operations. Widely adopted by power supply utilities, large‑scale factories, metallurgy plants, power plants and railway departments for electrical maintenance & inspection work.
YD series test transformers are improved products manufactured complying with the ministry standard for test transformers. They are used to conduct insulation strength tests under power‑frequency and DC high‑voltage for various high‑voltage electrical equipment, electrical components and insulating materials, serving as indispensable core equipment for high‑voltage tests. The control section and boost section of the complete set can be freely assembled in different combinations.
