AC Resonant Test System for High Voltage Cable Testing Variable Frequency Series Resonance Equipment for 10kV to 500kV XLPE Cable AC Withstand Voltage Test

The AC Resonant Test System for High Voltage Cable Testing is designed for AC withstand voltage testing of medium-voltage, high-voltage and extra-high-voltage XLPE cables.

Cable systems become increasingly capacitive as voltage level and cable length increase. Conventional AC test transformers may require large power capacity for these applications.

A variable frequency series resonant system provides an efficient solution by tuning the reactor and cable capacitance into resonance.

Series resonant systems are commonly positioned for 6 kV to 500 kV cable testing, although actual capability depends entirely on the specific configuration and project requirements.

Q: Can one system test different cable voltage levels?
A: Depending on the reactor and voltage configuration, one system may support multiple test ranges.

Q: Is it suitable for on-site cable testing?
A: Yes. Variable frequency resonant systems are widely used for field cable testing because the equipment can be configured in a modular structure.
