从China供应商批发进口3 Phase Transformer On-Load Tap Changer — FOB条款

The 3 Phase Transformer On-load Tap Changer tester from Wuhan GDMK Electric Co., Ltd. is designed to measure and analyze the electrical performance of power transformers and special transformers during tap-changing operations. It captures transient time, transition waveform, transition resistance, and synchronization state, providing a comprehensive assessment of on-load tap-changer behavior. The device supports a three-phase constant current source with charge currents of 3A/1A or 0.6A/0.2A, and it operates within a maximum port voltage of 24V.

Constructed for industrial testing, this tap-changer tester handles transition resistance measurements up to 100 ohms, with a waveform recording time of 300ms and a sample rate of 30kHz. It delivers time resolution of 0.1ms and resistance resolution of 0.1 ohm, with an accuracy of ±5% for transition resistance and ±0.5% for transient time. The unit is built to function in temperatures ranging from -10°C to 40°C and is suited for environments with varying humidity levels, typical of field testing conditions.

This equipment is primarily used by utilities, transformer manufacturers, and service providers to verify the operational integrity of on-load tap-changers in high-voltage transformers. Buyers typically include electrical testing labs, power distribution companies, and maintenance contractors who require precise diagnostics to ensure grid reliability. The tester’s ability to automate data capture and display transition parameters makes it a critical tool for preventive maintenance and fault detection in power infrastructure.

Wuhan GDMK Electric Co., Ltd. is based in Jiangxia District Economic Development Zone, Wuhan, China, with its registered address at Huangjiahu Avenue in the Daqiao New District. The company operates from a facility located in the 430200 postal area, serving as a manufacturer and supplier of electrical testing equipment, including transformer on-load tap-changer testers.

The supplier holds a harbor trust tier, indicating a baseline level of verified business information. While the response rate and average response hours are currently not available, the company’s focus on specialized electrical testing tools suggests a commitment to technical precision. Buyers are advised to confirm communication channels and support availability directly with the supplier before placing orders.
