Import 3kva/5kv Power Frequency Withstand — Buy in wholesale FOB from Supplier in China

The 3KVA/5KV Power Frequency Withstand from Wuhan GDMK Electric Co., Ltd. is a portable voltage tester designed for field use, integrating over-current protection, high-voltage output, and direct reading instrumentation in a single unit. Its compact design, achieved through a reasonably structured layout, ensures light weight and ease of transportation, making it suitable for on-site testing in power systems. The unit features a current relay for over-current protection, a timing indicator, and a zero point/closing indicator, all housed within the voltage stand for streamlined operation.

Constructed with precision, this tester employs a new time relay to provide a wider timing range, enhancing its adaptability to different test scenarios. The current relay is upgraded for higher precision and reliability, ensuring personal and equipment safety during high-voltage testing. The integrated design eliminates the need for separate components, reducing setup time and complexity. Typical applications include power frequency withstand voltage tests on transformers, cables, and switchgear, where consistent performance under varying conditions is critical.

Industrial buyers such as power utilities, electrical contractors, and testing laboratories use this equipment to verify insulation integrity in high-voltage systems. The unit is designed for bulk supply, with packaging suitable for export. Buyers should confirm logistics details, including lead time and Incoterms, directly with Wuhan GDMK Electric Co., Ltd. The tester is compatible with standard power frequency test procedures, making it a practical choice for routine and diagnostic testing in electrical infrastructure.

Wuhan GDMK Electric Co., Ltd. is based in Jiangxia District Economic Development Zone, Daqiao New District, Wuhan, China, with its operations centered in this industrial hub. The company specializes in power testing equipment, offering products designed for practical, reliable field use. Its address places it within a region known for electrical and mechanical manufacturing, aligning with its focus on power system solutions.

The supplier’s profile indicates a harbor trust tier, reflecting a baseline level of verification. While the response rate and average response hours are currently listed as zero, this may indicate a focus on direct inquiries rather than platform-based communication. The company’s product range, as evidenced by this listing, targets industrial power testing needs, with an emphasis on portability and safety in high-voltage environments.
