Composite Insulators: A Potential Path Towards Eco-Friendly GIS Designs

Gas Insulated Switchgear (GIS) offers a compact and reliable solution for high and medium voltage power transmission and distribution. However, its reliance on Sulfur Fluoride Hexafluoride (SF6) gas as the primary insulating medium raises significant environmental concerns due to SF6's high global warming potential (GWP). The search for sustainable alternatives to SF6 is a key focus area for the power industry. Composite insulators, made from non-gaseous materials, offer a promising path towards eco-friendly GIS designs. This article explores the development and implementation of composite insulators as an alternative to SF6 gas in GIS, discussing the challenges and advancements in this technology.
