AC Dielectric Test System Power Frequency High Voltage Insulation Testing Equipment

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.

• Complete specifications & strong compatibility; control and boost units for arbitrary combination
• Advanced design and reasonable mechanical structure, durable construction
• Multi‑function for both AC & DC testing, compact and portable
• Support single‑unit operation or cascade connection for higher voltage output
• Multiple control options: Manual, Electric, Full‑automatic, Industrial PC control
• Optional printing, USB communication, PC connection; bilingual Chinese‑English interface
• Multiple insulation options: Oil‑immersed, epoxy dry‑type, SF6 gas, corona‑free type for diverse working conditions

Power supply bureaus, power plants, substations, metallurgy & mining, railway systems, industrial‑mining enterprises, research institutes and third‑party testing laboratories.
Used for power‑frequency withstand voltage & AC‑DC withstand voltage insulation test of high‑voltage switchgears, power cables, instrument transformers, arresters, insulators and insulating materials.
