从China供应商批发进口250v To 10kv Digital Insulation — FOB条款

The 250V to 10kV digital insulation tester from Wuhan GDMK Electric Co., Ltd. is designed for precise insulation resistance measurement across five fixed ranges: 500V, 1000V, 2500V, 5000V, and 10000V, with a test capacity reaching 10TΩ. It integrates live voltage measurement, leakage current detection, and automatic discharge for capacitive test objects, ensuring operator safety and instrument longevity. The device automatically calibrates before each test and records R15S, R60S, and R10min values, while calculating the polarization index (PI) and dielectric absorption ratio (DAR) in real time.

Constructed for industrial electrical testing, the unit features anti-jamming capabilities that maintain accuracy even with interference currents up to 600 mA. It supports both AC and DC power inputs via an internal rechargeable lithium battery or external AC supply, with no impact on measurement precision. The digital display provides battery level monitoring and undervoltage alarm protection, while short-circuit protection prevents instrument damage during faults.

This tester is suited for utilities, manufacturing plants, and electrical contractors requiring reliable insulation diagnostics for motors, transformers, cables, and switchgear. Typical applications include preventive maintenance, commissioning, and troubleshooting in high-voltage systems. Buyers should confirm compatibility with their test objects and verify the instrument’s calibration certificate before deployment.

Wuhan GDMK Electric Co., Ltd. is based in Jiangxia District Economic Development Zone, Wuhan, Hubei Province, China. The company specializes in electrical test equipment and has a registered address at Huangjiahu Avenue in Daqiao New District. Its product line includes high-voltage test instruments designed for industrial and utility applications, with a focus on safety and precision.

The supplier operates under the harbor trust tier, indicating a verified business presence. While response rate and average response time data are currently unavailable, the company’s product descriptions emphasize adherence to safety standards and advanced technical features. Buyers should directly contact the supplier to confirm certification status, production capacity, and lead times for specific orders.
