Profile:

The KDCT-120 addresses the critical need for a simple yet robust test terminal that eliminates corona interference and ensures stable PD performance during cable qualification. Its transparent high-strength insulating tube allows visual monitoring, while integrated sealing, grounding, and fluid valves enable quick setup with oil or water as the external insulation medium. Designed for mobility and ease of use, it delivers laboratory-grade test conditions—even in field substations or cable jointing sites.

Features:

Ultra-Low Partial Discharge: <2 pC at up to 100 kV
Dual Test Capability: Supports 120 kV AC and 250 kV impulse tests
Transparent Insulating Tube: Enables real-time visual inspection of cable end
Integrated Sealing System: Reliable cable root fixation with waterproof/oil-tight valves
Corona Shielding: High-voltage grading shield minimizes surface discharge
Mobile Floor-Standing Design: Easy to position and operate on-site
Compliance Ready: Meets Chinese national standards for 35 kV cable testing
High Accuracy: Measurement accuracy class 0.01–0.05, ±(0.5% + 2 µΩ)
