Two decades of focus on making power distribution safer and smarter — from Liling, Hunan to projects worldwide.
Founded in 2008, Liling Huayi Electronic Technology Co., Ltd. develops and manufactures intelligent devices for medium and low-voltage power systems. Our products help utilities, EPCs and panel builders monitor, control and protect critical electrical assets.
Our engineering team controls the full chain from schematic design and firmware to enclosure tooling. This lets us respond quickly to custom requirements and keep lead times short for both standard and OEM/ODM orders.
Every product passes incoming inspection, functional testing and high-temperature burn-in before shipment. We continuously refine test fixtures so that field performance matches the datasheet.
Steady growth from a local instrument workshop to a global supplier.
Established in Liling, Hunan, focusing on electrical instruments and control devices.
Launched the YHK series intelligent switchgear control devices.
Introduced wireless contact temperature monitoring for switchgear.
Products exported to 80+ countries across Asia, Europe, Africa and the Americas.
RS485 / Modbus communication added across the portfolio for smart substations.
Products must work for years in harsh cabinet environments — we design for that.
Fast quotation, clear documentation and engineering support for every project.
Field feedback directly shapes the next revision of every device.
We grow with distributors and panel builders through OEM/ODM collaboration.
Developed to recognized international and national benchmarks.
