RSO-80 Silicone Transformer Oil : Guide
RSO-80 Silicone Transformer Oil meets IEC 836 and ASTM D 4652 standards for dielectric fluids, ensuring it is suitable for electrical insulation. It exceeds fire point requirements and is classified within IEC 1100 for low heat of combustion, presenting a lower fire hazard compared to other transformer fluids. It is difficult to ignite and will produce less heat and smoke if ignited, often self-extinguishing once the heat source is removed.
RSO-80 is VOC exempt, HAP-free, does not contribute to ozone depletion or global warming, and meets RoHS compliance, making it an eco-friendly choice for electrical systems.
