Import 80kv 0.1hz Vlf High Voltage Generator — Buy in wholesale FOB from Supplier in China

The 80KV 0.1Hz VLF High Voltage Generator from Wuhan GDMK Electric Co., Ltd. is designed for ultra-low frequency dielectric strength testing, offering a compact and portable alternative to bulky power frequency test equipment. This unit delivers a peak voltage of 80kV at frequencies as low as 0.1Hz, 0.05Hz, 0.02Hz, or 0.01Hz, with a load capacity of 25A and a theoretical cable test reach of 3 to 15 km for 35kV cables. The model VLF-80 incorporates a fuse-protected system and weighs less than conventional setups, addressing the practical challenges of on-site high-voltage testing.

Constructed for field use, the generator includes high-voltage terminals with nylon spin connections to ensure secure contact and prevent discharge risks. For cables shorter than 500 meters, a parallel 0.1μF high-voltage capacitor is required to maintain stable voltage boosting. The device adheres to standard VLF testing protocols, where a single-phase test is recommended for 35kV cables with voltage settings between 60kV and 78kV. Typical applications include commissioning tests for medium-voltage cables, where space and weight constraints make traditional equipment impractical.

This equipment is primarily sourced by electrical utilities, industrial plants, and testing laboratories requiring reliable dielectric strength verification. Buyers should confirm compatibility with their cable lengths and capacitance values before procurement. The unit is supplied as a standalone system, with no bundled accessories, and is designed for straightforward integration into existing test workflows. Lead times and packaging details are available on request from the supplier.

Wuhan GDMK Electric Co., Ltd. is based in the Jiangxia District Economic Development Zone, Wuhan, Hubei Province, China. The company operates from Huangjiahu Avenue in the Daqiao New District, with a registered address confirming its presence in a dedicated industrial zone. As a harbor-tier supplier, it is positioned to handle large-scale electrical equipment orders, though its response metrics currently reflect a 0% response rate and no recorded average response time.

The supplier specializes in high-voltage testing solutions, with the 80KV 0.1Hz VLF High Voltage Generator as a flagship product. Its profile does not include additional certifications, client lists, or operational history beyond the provided address and trust tier. Buyers are advised to verify the supplier’s technical support capabilities and after-sales service terms directly, as these details are not explicitly stated in the available information.
