Airing 24kV Series Dry Air Insulated Ring Main Unit

Description

Airing-24kV Eco-friendly Gas-insulated RMU is a core medium-voltage device. It replaces high-GWP SF₆ with pure dry air, integrating insulation and arc-extinguishing for zero emissions and eco-compliance.

Featuring self-energy load switch and vacuum circuit breaker technologies, it meets IEC standards with long service life. Its sealed, high-protection gas tank resists harsh environments, adaptable to urban, industrial, commercial and new energy systems. Compact, low-maintenance and reliable, it ensures stable, efficient distribution.

Features

Certifications
Complies with EU F-gas Regulation (EU) 2024/573
Complies with IEC standards and GB standards, and holds TÜV Rheinland certification report

SF₆-Free
Pure dry air is used as the insulation and arc-extinguishing medium, with a global warming potential of 0 (GWP=0), making it environmentally friendly

Safety
The rated filling pressure (abs. 20℃) is only 0.15 MPa, with an annual gas leakage rate of less than 0.01%, ensuring safer operation

Reliability
With insulation capability at 0.10 MPa gauge pressure zero (abs. 20℃), it meets the 50/60 kV requirement of IEC standards, ensuring more reliable operation

Protection
The earthing switch stably meets the Class E2 closing requirements, providing core protection for the safe and stable operation of the distribution network

Flexibility
Featuring a standard modular design and compact structure, the unit-type and common-box-type cabinets can be flexibly combined to meet diverse application scenarios

Intelligence
It can be equipped with Xiamen Huadian iEDS Intelligent Digital Detection System to achieve full-life-cycle intelligent management
