C4-FN Mixtures for High-Voltage Equipment Handbook

This document is a handbook detailing the environmental benefits of C4-FN mixtures in high-voltage equipment compared to traditional SF6 technology. It presents findings from various Life Cycle Assessments (LCAs) that indicate C4-FN mixtures can reduce the total carbon footprint of high-voltage equipment by 59% to 92%. The document outlines specific case studies, including a dead-tank circuit-breaker and a gas-insulated switchgear (GIS), highlighting significant reductions in carbon emissions during manufacturing and use phases. It also discusses the impact of material choices, such as the use of recycled aluminum, on overall carbon footprint. The handbook emphasizes that while C4-FN mixtures may require slightly more material, their lower global warming potential (GWP) during operation leads to a net reduction in emissions. Additionally, it addresses the potential for retrofilling existing SF6 installations with C4-FN mixtures to further decrease carbon footprints. The findings are supported by verified studies and aim to inform stakeholders about the advantages of adopting C4-FN technology.
