Wuhan, China – Wuhan Huayi Power Technology Co., Ltd. (Wuhan Huayi) is pleased to announce the successful export of a high-performance 80kV VLF (Very Low Frequency) High Voltage Generator to a prominent power engineering services provider in the Philippines.
The equipment is destined for a critical infrastructure project: the commissioning and final acceptance testing of a new high-voltage substation, ensuring the long-term reliability of the local power grid.
Substation Commissioning: The Gold Standard for Reliability
In the Philippines' rapidly expanding energy sector, the "Acceptance Phase" of a new substation is a zero-tolerance mission. Utility operators require definitive proof that all underground XLPE (Cross-Linked Polyethylene) cables and high-voltage assets can withstand operational stress without latent defects.
The 80kV VLF unit was selected for this project due to its:
High Voltage Capacity: Capable of testing cables rated up to 35kV (and even certain 66kV configurations) according to IEEE 400.2 standards.
Non-Destructive AC Testing: Unlike traditional DC Hipot, which can leave harmful "space charges" in XLPE insulation, our VLF technology provides a safe, sinusoidal stress test that mimics real-world AC operation.
Engineering for Portability and Precision
Philippine field conditions-ranging from dense urban centers to remote island sites-demand equipment that is as tough as it is precise. The delivered 80kV system features:
Miniaturized Architecture: Combining a high-power inverter with advanced ARM-based control, the unit fits into a portable chassis for easy transport.
Full Automation: Automated voltage ramping, timing, and breakdown detection ensure consistent results and reduce human operational error.
HSE-Ready Safety: Rapid response protection circuits (≤10ms) and automatic discharge mechanisms safeguard engineers during high-stakes substation work.
A Growing Partnership in the Southeast Asian Market
"The Philippine market is a cornerstone of our Southeast Asian strategy," said the Technical Export Manager at Wuhan Huayi. "By providing 80kV VLF systems that meet international IEC standards, we are helping local EPC partners deliver world-class substations that serve millions of people."
Every unit sent to the Philippines undergoes rigorous multi-stage calibration at our Wuhan facility, including Electromagnetic Compatibility (EMC) and accuracy verification against master reference meters.
