Fluorinated nitrile (C4F7N) is a potential SF6-alternative gas in Gas-Insulated Transmission Line (GIL) due to its lower impact to global warming and excellent dielectric strength. To ensure the long-term physical and chemical stability at the interface between C4F7N/CO2 gas and epoxy resin assembly in GIL. laboratory thermal ageing tests on the material compatibility were carried out... https://www.sneakerpolitices.shop/product-category/denim-jackets/
