Introduction:
Silicone Oil for Transformer is a high-performance insulating and cooling fluid formulated using premium-grade silicone polymers. It is designed to replace conventional mineral oils and synthetic esters in electrical equipment where enhanced thermal stability, oxidation resistance, and safety are essential. Its exceptional dielectric properties and non-flammable nature make it a reliable choice for transformers operating under demanding environmental and electrical conditions.Applications:
Power and distribution transformers
High-voltage electrical equipment
Capacitors and switchgear systems
Circuit breakers and bushings
Transformers installed in confined or fire-sensitive areas
Benefits:
Excellent dielectric strength for superior insulation performance
Outstanding thermal and oxidation stability for long service life
Non-flammable and self-extinguishing, ensuring improved safety
Wide operational temperature range suitable for extreme climates
Low viscosity for efficient heat dissipation and cooling
Chemically inert and compatible with most transformer materials
Environmentally stable with minimal degradation over time
