The lightning impulse voltage generator test device under Wuhan UHV can help many power workers conduct various power tests more conveniently.

In the insulation performance testing of power cables, the cable impulse voltage tester is an indispensable key equipment, and its procurement selection directly affects the accuracy of the testing results and the safety of cable operation. The cable impulse voltage tester of Wuhan UHV Power Technology Co., Ltd. has become the preferred target for procurement due to its performance and full process service advantages in adapting to multiple cable types.

The Wuhan UHV cable impulse voltage tester has outstanding technical adaptability. This device covers voltage levels from 10kV to 500kV and can be used to test cables made of different materials such as cross-linked polyethylene cables, oil paper insulated cables, and rubber insulated cables. It supports two waveforms: lightning impulse (1.2/50 μ s) and operational impulse (250/2500 μ s), with waveform parameter errors controlled within ± 3%, fully complying with national standards such as GB/T 17627. The modular Marx generator design it adopts can flexibly adjust the output voltage by adding or removing modules, which can meet the routine testing requirements of low-voltage cables and also adapt to the rigorous testing needs of ultra-high voltage cables, without the need to repeatedly purchase equipment due to changes in cable specifications.

The intelligent and secure design of equipment adds practical value to procurement. The intelligent control system equipped on the tester supports fully automatic charging and discharging processes, and can preset parameters such as impact frequency and interval time. During the test, real-time voltage waveform and cable leakage current data are collected, and the insulation status is automatically determined through built-in algorithms to avoid manual reading errors. In terms of safety protection, the equipment is equipped with dual overvoltage protection, grounding interlock devices, and emergency shutdown systems. In case of sudden situations such as cable insulation breakdown, the high-voltage output can be instantly cut off. At the same time, the chassis adopts a fully metal shielding structure, effectively blocking electromagnetic radiation and ensuring the safety of operators.

Customized services during the procurement process are further tailored to meet actual needs. Wuhan UHV can adjust equipment configuration according to cable testing scenarios: for on-site testing of underground cable wells, we provide portable split type models, which reduce the weight of the host by 50% compared to traditional equipment, and are equipped with foldable high-voltage leads for easy operation in small spaces; Customized multi station testing platform for batch cable factory inspection, supporting synchronous impact testing of 3 sets of cables, increasing testing efficiency by more than twice. When purchasing from a certain cable production enterprise, the technical team also installed a cable partial discharge synchronous detection module according to their needs, achieving integrated operation of impact withstand voltage and partial discharge detection, reducing equipment connection links.

A comprehensive post procurement service system provides assurance for the long-term operation of equipment. Wuhan UHV promises to provide free on-site installation and commissioning after equipment delivery, and arrange technical personnel to conduct practical training, covering waveform calibration, data interpretation, and daily maintenance points. The equipment has a 5-year warranty period, and 20 after-sales response centers across the country can achieve 4-hour remote fault diagnosis and 24-hour on-site support. For bulk purchasing users, regular inspection services are also provided to monitor equipment operation status through a cloud based data platform, early warning of potential issues such as component aging, and reduce maintenance costs.

From technical adaptation to after-sales support, Wuhan UHV provides reliable support for the procurement of cable impulse voltage testers with the dual advantages of "equipment performance+scenario service". Whether it is the factory quality inspection of cable production enterprises or the on-site acceptance of power operation and maintenance units, choosing Wuhan UHV equipment can not only provide accurate and stable testing tools, but also enjoy procurement services that meet actual needs, laying a solid technical defense for cable insulation safety testing.
