RMU 40.5kV

In the context of the growing demand for modernization of power distribution systems, electrical equipment must not only ensure safety but also deliver durability, stable operation, and suitability for harsh environmental conditions. The RMU switchgear manufactured by Eaton’s Cooper is one of the advanced solutions, distributed by Mỹ Phương Company (MP Co), fully meeting all of these requirements.

The product is suitable for power utility projects, industrial and residential infrastructure developments, high-rise buildings, airports, and seaports.

Key Features:

• The RVAC switchgear is capable of withstanding short-circuit currents up to 25kA/4s, ensuring system stability even during major faults. Additionally, the device is designed for 4-sided arc resistance according to the AFLR 25kA/1s standard, providing maximum protection for operators and the surrounding environment. Thanks to its effective fault isolation capability, the product minimizes the risk of explosion and widespread damage within the electrical system.
• The switchgear utilizes SF6 gas as the primary insulating medium for both busbars and switching devices, enhancing insulation efficiency and maintaining reliability throughout operation. The sealed SF6 gas compartment design, with an extremely low leakage rate (< 0.1%/year), ensures continuous performance for many years. Thanks to this factor, the operational lifespan of the product is extended from 20 to 30 years without the need for frequent maintenance.
• The product is manufactured in accordance with strict international standards such as IEC 62271-1, IEC 62271-100, IEC 62271-102, IEC 62271-103, and IEC 62271-200, ensuring quality and stable operation under all conditions. The RVAC switchgear has successfully passed type tests at the world-leading DEKRA lab (STL) – a globally recognized organization for electrical equipment assessment.
• The RVAC switchgear is designed to withstand and operate reliably under harsh environmental conditions, including high temperatures, high humidity, and environments with heavy dust or corrosive elements. Thanks to its robust protective enclosure and highly efficient insulation system, the product maintains optimal performance even in demanding operating conditions. This is a key factor that makes RVAC a preferred choice for outdoor installations, seaports, airports, and heavy industrial facilities.
• Full range of functional units: Load Break Switch functional unit [K], Circuit Breaker functional unit [V] (Vacuum Interrupter), Metering functional unit [M]

Wide Range of Practical Applications

With its robust configuration, outstanding safety features, and optimized design, the RMU switchgear is the ideal solution for:

• Power distribution substations in industrial parks and residential areas.
• High-rise buildings and commercial centers.
• Airports, seaports, and areas with harsh operating environments.
• Medium-voltage substations in power distribution systems.
