The KD-2163 is a complete, four-part cable fault testing system developed by Wuhan Kaidizhengda Electric Co., Ltd. It integrates advanced testing technologies to provide a full workflow from fault distance measurement to precise pinpointing. The system consists of the KD-2163 Main Tester for distance measurement, the KD-216D Multi-Pulse Generator for simplifying complex fault waveforms, the KD-210Z Integrated High-Voltage Power Supply for safe and controlled fault excitation, and the KDZD850 Ultra-Quiet Precision Pinpointer for accurate on-site fault location. With its large touch screen, intelligent controls, and rugged design, the KD-2163 offers a highly efficient and user-friendly solution for cable fault diagnosis.

• Complete Four-in-One System: Includes all necessary components for a full cable fault diagnosis workflow: the KD-2163 Main Tester, KD-216D Multi-Pulse Generator, KD-210Z High-Voltage Power Supply, and KDZD850 Precision Pinpointer.
• Advanced Multi-Pulse Technology: The KD-2163 main unit uses multi-pulse and arc reflection methods to simplify the analysis of high-resistance and flashover faults, making waveform interpretation easier and more reliable.
• Intelligent Main Tester: Features a large 12.1-inch industrial LCD screen with both touch and knob/mouse control. It offers eight automatic sampling frequencies (up to 400MHz) and can store 32GB of data.
• Ultra-Quiet Pinpointing: The KDZD850 pinpointer uses BNR (Background Noise Reduction) technology and high-sensitivity sensors to clearly identify fault discharge sounds, even in noisy environments, for precise location.
• Directional Guidance: The KDZD850 features visual arrow indicators that guide the operator towards the fault and help keep them aligned directly over the cable path.
• Safe & Integrated HV Supply: The KD-210Z power supply is a fully integrated unit with a touch screen interface, automatic voltage regulation, and safety features like emergency stop and automatic discharge upon shutdown.
• Rugged & Portable Design: The main tester is powered by a built-in lithium battery for field use, and the high-voltage unit is housed in a durable, wheeled engineering case for easy transport.
• Remote Data Transfer: The main tester is equipped with Wi-Fi and a SIM card slot, allowing for wireless data transfer to mobile devices for remote technical support and analysis.
