The Medium Voltage Ring Main Unit is a highly versatile and reliable compact switchgear solution, ideally suited for applications with limited distribution facility space and demanding reliability requirements. Designed to excel in challenging environments, this switchgear combines state-of-the-art microprocessor technology, advanced network communication, and innovative switch manufacturing to deliver unparalleled performance.

At the core of the Metal-Enclosed Ring Main Unit is its fully insulated and fully enclosed cabinet-style stainless steel casing. This robust design effectively isolates the high-voltage components, including circuit breakers, three-position switches, and load break switches, from external environmental factors. As a result, the Ring Main Unit is impervious to water, fire, explosion hazards, chemical corrosion, and severe vibrations, ensuring exceptional reliability and long-term safe operation even in the harshest of conditions.

The compact size of the Ring Main Unit is another key advantage, making it an ideal choice for applications where space is limited, such as industrial and mining facilities, substations, subways, and light rail networks. The miniaturized high-voltage components and the sealed casing contribute to this compact footprint, while also eliminating the risk of corrosion and rust that can affect exposed equipment.

Underpinning the Ring Main Unit superior performance are its advanced measurement, protection, control, and communication functions. Fully compatible with distribution automation systems, this switchgear can seamlessly integrate with your operational infrastructure, providing comprehensive monitoring, control, and data management capabilities to optimize your power distribution network.
