Profile:
The KDZD-212C Cable Reel Multi-Parameter Field Tester is a professional diagnostic instrument engineered for rapid, on-site quality verification of power cables. Leveraging advanced traveling wave testing technology combined with multi-electrical parameter comprehensive diagnosis, this instrument delivers a complete cable assessment solution without requiring laboratory conditions. The device directly measures cable length, conductor DC resistance, and ambient temperature, then automatically calculates unit length conductor resistance and effective cross-sectional area. It offers two flexible measurement modes — local measurement and wireless remote measurement via a built-in Bluetooth module — enabling operators to adapt seamlessly to complex field environments. A comprehensive protection system featuring lithium battery charge/discharge management, over-voltage and over-current protection, and internal over-temperature protection ensures safe and dependable operation. With a precision DC resistance measurement module delivering ±0.2%+1μΩ accuracy and a high-precision pulse time counting module supporting length measurements from 30m to 50km, the KDZD-212C brings laboratory-grade results to field conditions. The integrated temperature and humidity sensor provides automatic environmental compensation for enhanced accuracy. Powered by a high-capacity 12.6V 15000mAh lithium battery, it provides over 20 hours of standby time and more than 8 hours of continuous measurement. Compliant with GB/T 3956-2008 and GB/T 6587-2012, the KDZD-212C is the ideal solution for cable manufacturers, electrical inspectors, and power utility companies.
