The KDZG-II 60kV/10mA DC High Voltage Generator is a compact, high-stability test system designed for DC withstand and leakage current testing of zinc oxide surge arresters, power cables, transformers, switchgear, and rotating machines. Compliant with Chinese industry standard ZGF24003-90, it delivers precise, low-ripple DC output up to 60 kV with integrated safety protection—ideal for field use in power utilities, industrial plants, and laboratories.
The KDYDJ-6kVA100kV series excited power frequency withstand voltage test device is a supporting equipment for lightweight high-voltage test transformers. It has excellent performance, multiple functions, small size, light weight, reliable use, beautiful appearance, and easy operation and maintenance.
AC Withstand Voltage Test Device (100kV)
The KDYDJ-420kVA 30kV AC Withstand Voltage Test System is a robust, high-capacity testing solution designed for long submersible cables (up to 3000 meters with a core cross-sectional area of 42.5 mm²). It provides precise AC voltage testing up to 30 kV and can sustain this voltage for 10-60 minutes without breakdown, ensuring cable insulation integrity. The system includes advanced safety features like automatic overvoltage/overcurrent protection, fault alarms, and harmonic stabilization.
