What are the key dielectric properties of silicone oil used in transformers?

Silicone oil used in transformers exhibits exceptional dielectric properties that make it an ideal insulating fluid. Its high dielectric strength allows it to withstand significant electrical stresses without breaking down, ensuring effective insulation between conductive components. The oil maintains a stable dielectric constant over a wide temperature range, providing consistent performance under varying operating conditions. Additionally, silicone oil has a low dielectric loss factor, meaning it dissipates minimal energy as heat when subjected to electric fields, which enhances the efficiency of the transformer.
