What are the cooling properties of silicone oil in transformer systems?

Silicone oil has excellent cooling properties due to its high thermal conductivity and specific heat capacity. It effectively absorbs heat from transformer components and transfers it to cooling systems or dissipates it into the environment. The oil’s stable viscosity ensures consistent flow rates, enabling efficient heat exchange even at varying temperatures. This efficient cooling prevents overheating, reduces thermal aging of insulation, and enhances transformer reliability.
