从China供应商批发进口Ac Resonant Test System — FOB条款

The AC Resonant Test System from Wuhan GDMK Electric Co., Ltd. is engineered for 35kV cable AC withstand voltage testing, leveraging frequency adjustment to achieve resonance between the reactor and the test capacitor. This method generates high voltage and large current on the test product with minimal power input, as the resonant excitation power supply requires only 1/Q of the test capacity. The system supports a rated voltage of 1.108kV, sufficient for 35kV cable tests, and maintains a waveform distortion rate of less than 1.0% for output voltage.

The device is designed for portability, with components limited to 30kg for single-person transport and 60kg for two-person handling, making it suitable for on-site use. Constructed with dry epoxy casting reactors, it is reliable for various cable types and operates on 220V or 380V single-phase power supplies for flexibility. The system’s quality factor is Q 50, reducing weight and volume by 1/10 to 1/30 compared to conventional units, while the advanced IPM module ensures stability under minimal weight conditions.

This system is primarily used by utilities and testing labs for high-voltage cable certification, field commissioning, and routine maintenance. Its ability to prevent large short-circuit currents from damaging fault points makes it ideal for repetitive testing in harsh environments. Buyers typically confirm compatibility with their cable voltage levels, verify the system’s portability for their site conditions, and ensure the power supply matches their available infrastructure.

Wuhan GDMK Electric Co., Ltd. is based in Jiangxia District Economic Development Zone, Daqiao New District, along Huangjiahu Avenue in Wuhan, Hubei Province, China. The company specializes in high-voltage testing equipment, with a focus on portable and efficient solutions for field applications. Its address and operational location confirm its presence in a key industrial hub for electrical testing technology.

The supplier’s profile indicates a Harbor trust tier, though its response rate and average response hours are currently unrecorded. The listing highlights its expertise in designing systems for cable testing, emphasizing practical on-site usability and technical precision. No additional claims about certifications, client base, or production scale are provided, and buyers are advised to contact the supplier directly for verification of specific capabilities.
