  • Free warranty
    12 month

  • On-line training
    Support

Profile:

The KDCT-120 eliminates corona interference and ensures stable test conditions by using oil or water as an external insulation medium. Its transparent design allows real-time visual inspection of the cable termination, while integrated sealing and grounding mechanisms guarantee safety and repeatability. Compact, mobile, and easy to operate, it brings laboratory-grade high-voltage testing capability directly to substations, jointing sites, or manufacturing floors.

Features:

✅ Ultra-Low PD Performance: <2 pC background noise at up to 100 kV
✅ Dual-Mode Testing: Supports 120 kV AC and 250 kV impulse voltage tests
✅ Transparent Insulation Tube: Enables direct observation during testing
✅ Integrated Fluid System: Quick-connect valves for oil/water filling and draining
✅ Corona Shielding: Minimizes surface discharge at high voltage
✅ Mobile Floor-Standing Design: Equipped with wheels for easy transport
✅ Standards Compliant: Meets GB/T 12706.3-2020 and GB/T 31489.4-2020
✅ Rugged & Field-Ready: Operates immediately after transport—no settling time required
