40KV VLF High Voltage Generator
The 40KV VLF High Voltage Generator from Wuhan GDMK Electric Co., Ltd. is a precision diagnostic tool designed for testing the insulation integrity of power cables and electrical equipment using Very Low Frequency (VLF) technology. Operating at an output frequency of 0.1Hz, the device applies controlled high voltage to detect insulation faults, such as partial discharges or weak spots, before equipment is deployed in the field. This makes it essential for utility companies, cable manufacturers, and electrical contractors performing preventive maintenance or quality assurance.
The generator features a steel housing with copper winding components and epoxy insulation, ensuring durability and resistance to electrical stress. It is capable of testing cables and generators with corresponding voltage ratings, with a load capacity of up to 20 µF at 0.1Hz. The instrument includes a control body and boost module, weighing approximately 50 kg, and is designed to overcome the shortcomings of mechanical VLF methods, such as non-standard sine waves and measurement errors in high-voltage testing.
Primary applications include testing medium-voltage cables, transformers, and switchgear in power transmission and distribution networks. The generator is particularly valuable for detecting faults in aged or degraded insulation, helping to prevent costly failures and outages. Buyers should confirm the unit’s compatibility with their specific test objects, as the capacitance of the test product must not exceed the instrument’s rated capacity. The device is typically used in conjunction with other diagnostic tools, such as partial discharge detectors, for comprehensive insulation assessment.
| Rated Voltage | 40kV (peak) |
| Output Frequency | 0.1Hz (standard for VLF testing) |
| Load Capacity | 20 µF at 0.1Hz |
| Fuse Rating | 20A |
| Weight | 50 kg |
| Material | Steel Housing with Copper Winding Components and Epoxy Insulation |
| Minimum Test Capacitance | 0.05 µF (below this, output may be unstable) |
| Auxiliary Capacitor | 0.05 µF (for parallel connection to stabilize output) |
| Typical Applications | Cable and generator testing at corresponding voltage levels |
| Waveform | Standard sine wave (avoids errors in high-voltage measurement) |
Wuhan GDMK Electric Co., Ltd. is located in the Jiangxia District Economic Development Zone, Daqiao New District, Wuhan, Hubei Province. The company operates from Huangjiahu Avenue and specializes in the manufacture of electrical testing equipment, including high voltage generators and diagnostic tools for the power industry. Its location in a designated economic development zone suggests access to industrial infrastructure and logistics networks.
The supplier holds a harbor trust tier, indicating a verified presence in the supply chain. While the response rate and average response hours are not specified, the company’s profile confirms its focus on producing precision instruments for insulation testing. The listing does not provide details on certifications, production scale, or export markets, so buyers should request these directly to assess the supplier’s capabilities.
The 40KV VLF High Voltage Generator is a precision instrument designed for testing electrical insulation integrity in power cables and equipment using Very Low Frequency technology. Operating at 0.1Hz output frequency, this device applies controlled high voltage to detect insulation faults before field deployment, making it essential for utility companies, cable manufacturers, and electrical contractors. As a specialized diagnostic tool rather than a power source, it plays a critical role in quality assurance and preventive maintenance across the power transmission and distribution industry, supporting safe and reliable grid operations worldwide.

Sourcing 40KV VLF High Voltage Generator from Wuhan GDMK Electric Co., Ltd. - China Import Guide
Before placing an order, verify the generator’s rated voltage, output frequency, and load capacity to ensure compatibility with your test objects. Request the supplier’s calibration certificates and test reports to confirm the instrument meets industry standards, such as IEEE 400 or IEC 60060. Clarify whether the unit includes accessories like test leads, auxiliary capacitors, and user manuals, as these are essential for proper operation.
Discuss logistics, including packaging, shipping, and lead times. VLF generators are typically shipped as delicate instruments, so confirm the supplier’s packaging standards to prevent damage during transit. Clarify the Incoterms (e.g., EXW, FOB) and payment terms, and ensure the supplier can provide the necessary export documentation, such as commercial invoices and packing lists. For international shipments, verify compliance with import regulations in your country.
Upon receipt, conduct a thorough inspection to ensure the generator is free from physical damage and that all accessories are included. Perform a functional test using a known-good test object to verify the instrument’s accuracy and stability. Request additional documentation, such as maintenance records and warranty information, to ensure long-term reliability. Establish a calibration schedule to maintain the generator’s accuracy over time.
