types of rmu

Is there anything you ever wonder on the variety of RMUs there are? You have, and you are at the right place! In this article, we will discuss everything you need to know about RMUs including what an RMU is, different types of RMUs, the essential features one would look for in an RMU, and the positives and negatives of all available types. By the end, you will know what RMUs are and how they are improving our electricity systems.

First, let’s learn what an RMU actually is. A ring main unit (RMU) is a type of equipment used in electrical systems. It serves to protection, control and isolation system for electrical equipment in power network. An RMU is like a superhero for electricity — you can think of it as a powerful, self-contained power supply. Just like a superhero guarding a treasure, an RMU protects electricity so that it can be safely delivered to our houses and industries. Your knowledge of RMUs will solve: RMUs are important because without these, we could face certain issues with our electricity.

Understanding the Different Types of RMUs

Gas insulated RMUs is compact, its size is one of the main distinguishing features. This is especially useful in tight city environments where space is at a premium. Another good thing is gas insulated RMUs have high reliability. They don’t fall apart easily and require minimal maintenance or repairs throughout their lifespan. Also, SF6 gas is safe for the environment, nurturing the presence of Mother Earth!

Another benefit of the oil insulated RMUs is that they are typically cheaper than their gas insulated counterparts. This makes them ideal for individuals or corporations looking to pinch pennies. Oil insulated RMUs are also simpler to install and maintain that can save both time and labor. These become widely used option for many applications as compared to gas insulated RMUs due to its ease of working.

Key Features of Gas Insulated RMUs

Similarly oil-insulated RMUs have some disadvantages too. One big downside is they need to be maintained and checked regularly. The shit is used as an insulating oil sometimes, so it can wear out and have to be replaced periodically to keep everything running. For users of them, this can be an additional task. Additionally, oil insulated RMUs are larger in size as compared to gas insulated RMUs, making them a less appropriate selection for the places which do not have a lot of space available.
Advantages and Disadvantages of Oil Insulated RMUs

There are RMUs which take advantages from both gas insulated RMUs and oil insulated RMUs. These unique RMUs use gas for insulation of the critical components inside, while the exterior uses oil for insulation. This allows them to be made small and low-maintenance, whilst still benefitting from the cost savings associated with oil insulation. This makes them a great option for a wide variety of applications!
