In today's increasingly complex power grid construction and operation, the insulation withstand voltage test of high-voltage cables is no longer limited to laboratories. Whether it is transmission lines in deep mountain canyons, winding cable tunnels underground in cities, or outdoor construction sites in the cold winter of the north, the operating environment faced by testing equipment is becoming increasingly harsh. Equipment not only needs to be "accurately measured", but also "stand steadily and withstand". As a leader in the high-voltage electrical testing industry, Wuhan UHV Power Technology Co., Ltd. has been deeply involved in the industry for 22 years. Its VLF high voltage generators provide extreme testing solutions for power grid companies at all levels with excellent environmental adaptability and on-site operation capabilities.
Lightweight and split design, solving the problem of outdoor transportation
Portability is the first hurdle for fieldwork. The Wuhan UHV VLF high voltage generator adopts a modular and split structure design, with the main unit and control unit separated. The weight of each unit is strictly controlled within 20kg, and one or two on-site personnel can easily transport it. Whether climbing iron towers, crossing narrow cable trenches, or transitioning on rugged mountain roads, the equipment can be quickly positioned, greatly reducing the workload of frontline teams and improving testing efficiency.
Fully sealed protection and wide temperature range operation, fearless of harsh weather and extreme temperature differences
Environmental challenges are everywhere, from the damp and rainy substations in the south to the snowstorms of minus 20 degrees in the north. The shell of Wuhan UHV VLF series products is made of high-strength engineering materials, which have dustproof and waterproof capabilities, effectively resist rain, snow, and dust invasion, and ensure the safety and reliability of internal precision circuits. In response to the winter operation needs in cold regions, the equipment is equipped with industrial grade wide temperature LCD screens and low-temperature resistant components, which can start and operate normally and stably at temperatures as low as minus 15 ℃ or even lower, completely eliminating the embarrassment of "black screen when starting up and striking at low temperatures" during winter field testing.
Intelligent battery power supply and wide voltage adaptation completely eliminate on-site power anxiety
At the field testing site, it is often difficult to connect to the mains power supply, and the generator power supply faces challenges such as voltage fluctuations and unstable frequencies. The Wuhan UHV VLF high voltage generator is equipped with a large capacity rechargeable lithium battery pack, which can meet the requirements of continuous multiple withstand voltage tests with one full charge, truly achieving "pick up and run, start up and test". At the same time, the device has the ability to adapt to wide voltage inputs and is compatible with generator power supply. Even if the on-site power supply voltage fluctuates significantly, it can still output stable and accurate high-voltage waveforms, ensuring the authenticity and reliability of test data.
Intelligent control and data management make on-site testing simpler and more standardized
In the face of complex on-site working conditions, the ease of operation directly affects the success or failure of the test. The Wuhan UHV VLF series products adopt a touch screen human-machine interaction interface, integrating automatic voltage boosting, timing, voltage reduction, and data storage functions. Testers only need to set parameters with one click, and the equipment can fully automatically complete the entire voltage withstand process. The test data can be saved in real-time and exported through a USB drive to generate standard test reports, which not only meets the needs of rapid on-site testing, but also meets the management requirements of power grid companies for data traceability and standardized reporting.
With 22 years of craftsmanship accumulation, Wuhan UHV has always focused on technological innovation and product upgrades in the field of high-voltage power testing. The VLF high voltage generator is a reliable tool tailored for field cable withstand voltage testing of power grid companies at all levels - lightweight, durable, intelligent, precise, and consistent no matter how complex the environment is.
Choosing Wuhan UHV means choosing a reliable solution that can withstand on-site testing.
