Project Background
Low-carbon policy pushing SF₆ out of medium-voltage switchgear.
Key Challenges
SF₆-free alternatives struggling with insulation, sealing and certification.
Sieyuan Solution
Proprietary clean-air insulation designed and certified to IEC requirements.
Technical Highlights
Zero GWP, a compact footprint and reliable sealing on a seven-week lead time.
Project Overview
Project Background
The global transition toward low-carbon energy has made zero-carbon power equipment an industry imperative. Conventional gas-insulated switchgear that relies on SF₆ is associated with high global warming potential (GWP) and no longer aligns with increasingly stringent international environmental standards.
Key Challenges
Technical Limitations of SF₆-Free Alternatives — Most SF₆-free solutions on the market could not guarantee the insulation performance, sealing, and operational stability required under 24kV operating conditions, making it difficult to meet strict international zero-carbon standards.
Stringent Certification Requirements — The South American market follows IEC international standards, which impose higher requirements on equipment design, performance, and certification than domestic standards. Completing the full set of type tests through internationally authoritative laboratories involved a complex process and high barriers to entry.
Adaptation to Local Operating Conditions — Power grid conditions and on-site application scenarios in South America differ significantly, requiring equipment with a smaller footprint, stronger weather resistance, and higher stability.
Sieyuan Solution
Clean-Air Insulation Technology — Sieyuan's clean-air insulation technology eliminates the need for high-carbon SF₆ gas entirely, achieving zero GWP and full compliance with international zero-carbon standards.
IEC-Aligned Design and Certification — The product was designed and developed in full accordance with IEC standards and passed the complete set of type tests conducted by STL, an internationally authoritative testing laboratory.
Optimized for Local Conditions — The product structure and manufacturing process were refined to suit South America's diverse operating environments, resulting in a compact, reliably sealed, and stable design suited to power distribution, municipal, and industrial applications.
Technical Highlights
Technology — Sieyuan's clean-air insulation technology eliminates SF₆ use entirely, achieving zero carbon emissions and reaching an internationally advanced technical standard.
Performance — The equipment combines a compact footprint with high stability and reliable sealing, suited to the demanding operating conditions found across South America.
Industry Impact — The project demonstrates Sieyuan MSC Green Series' ability to support the low-carbon upgrade of South America's power grids and contributing to the broader transition toward sustainable energy across the global power industry.
