What are the advantages of silicone transformer oil in fire-safe applications?

Silicone transformer oil provides high fire resistance, high thermal stability, and low flammability compared with mineral oil. This can reduce fire risk and support installation in buildings, tunnels, or dense urban sites. It also performs well across wide temperature ranges, supporting stable cooling and dielectric behavior. The disadvantages are higher cost and the need to verify compatibility with gaskets and insulation systems. In fire-safe projects, silicone oil is often justified by risk reduction and regulatory compliance.
