Cities around the world are growing. The consumption of electricity across the globe has also increased. This has resulted in increased demand for power distribution systems that are reliable and compact. One innovation supporting this demand is the ring main unit. These units are designed to ensure that the flow of electricity is steady and flexible, which makes them important in modern medium-voltage networks.
This blog will explore the essentials of the ring main unit and its importance. It also covers the key stats and growth drivers for the ring main unit market. Let’s dive in!
A ring main unit is a metal-enclosed switchgear system. It is present in medium-voltage power distribution networks, usually between 11kV and 33kV. The configuration of the unit allows electricity to flow in two directions. As such, power flow continues even if one part of the circuit is down.
There are various components in a ring main unit. These include circuit breakers, load break switches, isolators, and protection relays. All of these components are placed in a sealed and enclosed casing. The design allows for quick fault detection and isolation. At the same time, power keeps running through alternate routes. The small size and modular structure of these units make them suitable for urban substations and energy solutions from the renewable energy market.
Our analysis reveals the ring main unit market to witness sustained growth. The market for these units is expected to account for a CAGR of 6.2% from 2023 to 2032. The market is expected to reach USD 4,225.24 million by 2032.
In today's business landscape, a ring main unit is critical for ensuring end users have a safe and reliable power supply. It ensures grid stability, enhances safety and reliability, enables remote monitoring and control, facilitates grid expansion and upgradation, and reduces operating costs. The unit optimizes equipment use, reduces maintenance costs, and improves efficiency, making it an essential component of the electricity distribution network.
Gas-Insulated Ring Main Unit
The insulating medium in this type is gases such as sulfur hexafluoride. The use of gases offers strong electrical insulation and allows the equipment to be efficient. Gas-insulated units are suitable for crowded urban areas and industrial sites with limited space. They have a longer lifespan and are highly reliable. However, sulfur hexafluoride is a potent greenhouse gas, prompting market players to move towards eco-friendly alternatives.
Air-Insulated Ring Main Unit
Surrounding air is used as the insulating medium in air-insulated ring main unit. This makes them unit more sustainable and easier to maintain. Air-insulated ring main units are larger than their gas counterparts. However, they are easier to install and have a low cost, making them suitable for use in rural and semi-urban areas. Their use is common in developing nations and infrastructure projects where affordability and reliability are the focus areas.
Oil-Insulated Ring Main Unit
These ring main units make use of dielectric oil for insulation and arc-quenching. They were common in older systems. However, their use has declined over the years. This is because oil-insulated ring main units have high maintenance requirements. Then there are the safety risks associated with oil leaks or fires. Nevertheless, some older or specialized industrial setups still use them.
The future of the ring main unit market looks promising, driven by the following trends and growth drivers:
Smart Grids: Integrating a ring main unit with smart grid solutions from the smart grid market enables efficient power distribution, monitoring, and control. The growing adoption of smart grids is expected to boost the demand for RMU.
Renewable Energy: The shift towards renewable energy sources such as solar and wind power requires advanced RMUs to handle the fluctuating power supply and grid stability.
Upgradation of Aging Infrastructure: The aging power infrastructure in developed countries such as the US and Europe requires replacing old equipment with new and advanced RMUs, leading to market growth.
Urbanization and Industrialization: Rapid urbanization and industrialization in emerging economies such as India and China require the expansion of the power grid, driving the demand for RMU.
Digitalization and Automation: Adopting digitalization and automation technologies, such as the Internet of Things (IoT) and artificial intelligence (AI) in the power sector, increases the need for advanced RMUs to handle complex networks and data.
The market for ring main units is growing steadily, driven by the increasing demand for electricity, renewable energy, and smart grids. The future looks promising, driven by smart grids, renewable energy, and digitalization trends. RMU is an essential component of the electricity distribution network, ensuring grid stability, enhancing safety and reliability, enabling remote monitoring and control, facilitating grid expansion and upgradation, and reducing operating costs. The RMU market presents a significant opportunity for key players to gain a competitive edge by developing advanced and innovative products that cater to the growing demand
