A Ring Main Unit (RMU) is an electrical distribution system used in medium-voltage power networks. It is a type of switchgear that is used to isolate and protect electrical circuits. RMUs are typically used in industrial and commercial applications, such as factories, hospitals, and office buildings. They are also used in outdoor applications, such as substations and power distribution networks.
RMUs are designed to provide a safe and reliable power supply to the connected electrical circuits. They are typically equipped with a variety of safety features, such as over-current protection, short-circuit protection, and arc-fault protection. RMUs are also designed to be easy to install and maintain, and they are often used in conjunction with other types of switchgear, such as circuit breakers and transformers.
The RMU market is highly competitive, with a variety of manufacturers offering a wide range of products. Some of the leading companies in the market include ABB, Siemens, Schneider Electric, Eaton, and General Electric. Show Less Read more
