XHDP-80M 80kV VLF Ultra Low Frequency AC Hipot Tester
The XHDP-80M is an 80kV VLF (very low frequency) ultra-low frequency AC hipot tester built on digital variable-frequency technology and single-chip control. Voltage boost, step-down, measurement and protection are fully automated, and the all-electronic design makes the unit compact and lightweight. A large color touchscreen displays the output waveform directly, making 0.1Hz AC withstand voltage testing of 35kV-and-below power cables and motors clear, fast and safe.
Applications & Target Audience: Built for cable erection and installation contractors, urban distribution network operation and maintenance crews, industrial plant electrical departments, and wind, solar and energy-storage power station O&M teams that carry out AC withstand voltage commissioning and preventive testing on 35kV-and-below XLPE power cables and high-voltage motors.
B2B buyer note:
- For electrical equipment distributors, EPC contractors and testing service companies seeking a portable 80kV VLF hipot set with export-ready packing and technical support
- Ideal for buyers who must test long cable runs without transporting heavy 50Hz power-frequency test sets

Why the XHDP-80M
One Unit, Two UsesUnits rated above 60kV use a series structure with two boosters that can each be used independently, delivering true multi-purpose value.
Intelligent ProtectionNo manual protection settings needed. The instrument calculates over-voltage and over-current limits from the test object capacitance and test voltage, and reacts to sudden changes in under 20ms to capture discharges.
No Capacitance-Rise EffectA closed-loop negative-feedback control circuit removes the capacitance-rise effect, keeping the output voltage stable and accurate.
High-Side SamplingCurrent and voltage are sampled directly from the high-voltage side, so readings are accurate and reliable.
Extended DiagnosticsAdds DC, dielectric loss and partial discharge test functions to measure dielectric loss, capacitance, insulation resistance and partial discharge during the same withstand test.
Safe HV Output LineA 150kV high-voltage output line ensures safe, dependable connection during field testing.
Typical Field Workflow
- Connect the controller, booster(s) and test object following the on-screen wiring diagram, then power on.
- Set parameters on the touchscreen: test voltage (0 to rated value) and test time (1 to 99 minutes); the system limits values to the safe range.
- Auto boost and test - two pre-test cycles check for low-resistance faults and measure capacitance, then the instrument steps up to the set voltage at the correct frequency with intelligent protection active throughout.
- Discharge and report - the unit automatically discharges the test object at stop, and results can be printed or saved; up to 90 test records are stored for later printing.
FAQ
Q1: Who is the XHDP-80M designed for?
It is designed for cable installation contractors, urban distribution network O&M crews, industrial plant electrical departments, and new-energy (wind, solar and storage) station maintenance teams performing AC withstand voltage commissioning and preventive testing on 35kV-and-below XLPE cables and high-voltage motors.
Q2: What test voltage and cable types does it support?
It delivers an adjustable 30kV-80kV peak output at 0.1Hz-0.01Hz, and is mainly used for AC withstand voltage testing of power cables and motors rated 35kV and below, with load capacity of up to 6µF (within 50kV) and 4µF (above 50kV).
Q3: How long is the withstand test and can results be stored?
The test time is adjustable from 1 to 99 minutes (60 minutes is standard per the cable test code). The instrument can print or save each result and stores up to 90 records for later review and printing.
Q4: What safety protection does it provide?
It offers intelligent over-voltage, over-current, sudden-change and discharge protection with an action time under 20ms, and it automatically discharges the test object at stop - without the need to set protection values manually.
Q5: What makes it different from a conventional 50Hz hipot tester?
Its 0.1Hz VLF output dramatically lowers the reactive charging current, so a compact, lightweight set can test long cable runs that would otherwise need a heavy power-frequency test system. It also adds DC, dielectric loss and partial discharge test functions and uses a color touchscreen with real-time waveform display.
