Ring Main Unit (RMU)

In modern urban and industrial power networks, space is a luxury, and reliability is a necessity. Our ring main unit (RMU) is engineered to provide a compact, gas-insulated or air-insulated solution for secondary distribution networks. We have spent 11 years refining the modular architecture of the ring main unit (RMU), ensuring it offers flexible expansion and ease of maintenance. Our facility, which covers nearly 300 mu, is equipped with intelligent CNC processes to ensure that every gas-tight compartment is manufactured to the highest sealing standards. This meticulous attention to detail is why our group has been awarded the "AAA Credit Enterprise" status and continues to serve as a benchmark in Anhui's building energy-saving sector.

The durability of our ring main unit (RMU) comes from our high-strength new steel materials, which are lightweight yet highly malleable. We integrate intelligent multi-source automatic detection systems into our RMUs, allowing for real-time monitoring of power equipment on-site. This digitalization of hardware-backed by our partnership with institutes like Tsinghua University-ensures that our ring main unit (RMU) is safe for operation in harsh environments, from coastal wind farms to humid petrochemical zones. We take immense pride in our technical heritage; in 2019, our factory was the only construction industry representative from Anhui to exhibit at the China-CEEC Innovation Cooperation Conference in Europe.
