Huatech's Airing Ring Main Unit Makes a Brilliant Debut at 2026 BRICS New Industrial Revolution Exhibition

A brilliant debut on a global stage!

On May 27, the 2026 BRICS New Industrial Revolution Exhibition grand opened in Xiamen. Huatech proudly presented its self-developed Airing eco-friendly gas-insulated Ring Main Unit (RMU) at the event.

The Airing series features eco-friendly gas insulation, offering zero greenhouse effect, compact design, high reliability, and maintenance-free operation — fully meeting the needs of green power grid construction both in China and globally.

SF₆-Free · Zero Carbon Emissions
The Airing series uses clean, dry air as both insulation and interruption medium, with GWP = 0. It fully complies with the EU F-gas Regulation (EU) 2024/573 and meets IEC and GB standards, supported by TÜV Rheinland certification.
