What Huanyu Group does

Huanyu High-Tech Co., Ltd. (环宇高科有限公司) is a 50/50 joint venture between Huanyu Group (环宇集团), a Chinese low-voltage electrical manufacturer founded in 1989, and Eaton Electrical (伊顿电气), a global power management company founded in 1911. The joint venture was formally established in 2020-2021 with headquarters and primary manufacturing at Wenzhou Bridge Industrial Park in Yueqing, Zhejiang, plus three additional industrial bases in Shanghai, Nanjing, and Shenyang. The company employs roughly 1,300 people and sells primarily under the HUYU brand.

The company manufactures a broad low-voltage electrical portfolio across three core lines: Power Distribution Products (配电产品) covering terminals, distribution equipment, power supplies, and energy management; Industrial Control Products (工控产品) including contactors, relays, motor protection devices, and soft starters; and the NE New Energy Series, comprising high-voltage DC miniature circuit breakers (HUB9NEZ), molded case breakers (HUM9NEZ), and frame disconnect switches (e.g., HUW9NEGZ-4000, DC1500V) rated for photovoltaic, wind, and energy storage applications. The SMART electrical series and a proprietary 智慧配电 IoT platform add remote monitoring, automated management, and intelligent diagnostics for smart grid use cases.

Revenue is generated through hardware sales via a network of more than 400 authorized dealers and agents across 66 countries and regions, complemented by direct enterprise sales targeting state-owned utilities, industrial manufacturers, and infrastructure projects. The 2026 win of the State Power Investment Corporation (国家电投) annual box-type transformer breaker framework illustrates the enterprise sales motion. Customer segments span new energy, power, building/real estate, communications, machinery/manufacturing, and EV charging infrastructure, with international certifications (UL, CCC, CB, CE, TUV) supporting export markets.
