Profile:
The KDZD-JC Softening Breakdown Tester is a high-precision automated instrument designed to evaluate the insulation performance of enameled round wires, film-wrapped round wires, and flat wires (with conductor diameters ranging from 0.020mm to 3.000mm or flat dimensions up to 10mm×2mm) after thermal softening, adhering to international standards such as GB/T4074.6-2008/IEC 60851-6 and JB/T4279.8-2008. It features automatic temperature measurement, control, and adjustment, along with programmable settings for preheating duration, target temperature, and test time, enabling seamless execution of heating, load application, and voltage testing. The device supports three testing modes: fixed-temperature testing (heating to a specified temperature before evaluation), rising-temperature method 1 (100V±10V with a breakdown threshold of 5±0.5mA), and rising-temperature method 2 (155V±10V with a breakdown threshold of 20±1mA), ensuring accurate detection of insulation failure under thermal stress. Equipped with a 900W heating system capable of reaching up to 450°C, a compact 450×380×500mm chassis, and a 30kg weight, it integrates advanced current detection, time control, and motor-driven load application to deliver reliable results. The tester provides real-time feedback via alarms and on-screen notifications (e.g., "Sample Breakdown" or "Test Completed") and includes calibration protocols for voltage, short-circuit current, and sensitivity to maintain measurement accuracy. Its applications span quality assurance in wire/cable manufacturing, material R&D validation, and compliance testing, making it an essential tool for laboratories, production facilities, and research institutions requiring precise, repeatable thermal insulation performance analysis under standardized conditions.
