More About Air Insulated RMU

What is an Atmospheric Pressure Sealed Nature-Air Insulated RMU/Switchgear?

A:
An Atmospheric Pressure Sealed Nature-Air Insulated Ring Main Unit (ASNA RMU) is a power distribution unit where the main electrical components are housed in a sealed cabinet, using air at atmospheric pressure as the primary medium of insulation. The design of this switchgear ensures a leak-proof, fully insulated and low maintenance operation, with key components like the vacuum interrupters, load break switches, and bus-bars enclosed safely. With their fully enclosed and insulated construction, RMUs minimize the risk of electrical faults, providing enhanced safety in environments for industrial, commercial, and residential applications where reliability and protection are critical. With over 50,000 units operating worldwide for over a decade with proven safe, stable and fault-free performance, this power distribution unit works without SF₆, complying with the international trend. SF₆-free switchgear leads the development of sustainable RMU technology.
What are the advantages of box type substations?
- The box type substation is designed with a compact layout, taking up minimal space, which makes it ideal for urban areas or regions with limited space.
- The electrical equipment is arranged in a logical manner, making transportation, installation, and maintenance easier and more convenient.
- With advanced protection against external elements like water, dust, and corrosion, the substation ensures the long-term safety of the equipment inside.
- Built to withstand harsh environmental conditions, these substations provide reliable power supply in challenging settings.
- Internal electrical components are equipped with fireproofing, explosion-proof, and lightning protection measures, ensuring operational safety at all times.
- These substations reduce project timelines and enhance overall work efficiency, making them a practical solution for rapid deployments.
What is the status of Atmospheric Pressure Sealed Nature-Air Insulated RMU/Switchgear in China?

A:
In China, the atmospheric pressure sealed air insulated RMU has become a widely adopted solution within the power distribution networks of the country’s two largest state-owned grid companies: State Grid Corporation of China (SGCC) and China Southern Power Grid (CSG). Since its inclusion in their procurement catalog in 2017, the air insulated RMU has been recognized as a standard product, with both corporations making large-scale purchases each year. This marks a significant step forward in its adoption across the country, reinforcing its role as a reliable and environmentally friendly option for modern power distribution.
