RSO-80 Silicone Transformer Oil
RSO-80 Silicone Transformer Oil is an environmentally safe replacement for PCB containing askarels as the dielectric coolant for liquid-filled transformers. Its high thermal stability makes it a good choice for transformers that are located indoors or next to buildings where a thermally stable fluid is more critical.

RSO-80 Silicone Transformer Oil is a 100% Polydimethylsiloxane silicone oil (CAS# 63148-62-9) with a viscosity of 50cSt (centistoke) @ 25°C. RSO-80 Silicone Transformer Oil is formulated exclusively for use as a dielectric fluid and dielectric coolant in high voltage transformers transformers.
RSO-80 Silicone Transformer Oil is characterized by its high dielectric strength, high flash point, wide service temperature range, , low vapor pressure, good heat capacity values, low pour point, low viscosity change at extremely high and low temperatures, and inertness to virtually all substrates. It is a 100% PDMS silicone fluid that contains no additives (such as thermal stabilizers).
Unlike conventional PDMS Silicone fluids, RSO-80 is dehydrated to contain < 50ppm water content to ensure the highest degree of dielectric strength and stability.

RSO-80 Silicone Transformer Oil : Guide
RSO-80 Silicone Transformer Oil meets bothInternational Electrotechnical Commission IEC 836 “Specifications for silicone liquid for electrical purposes” (Silicone Fluid Type T-1) and
ASTM D 4652 “Silicone Fluids for Electrical Insulation specifications for repair or top-off of existing liquid-filled units. These standards cover both the physical and electrical properties of fluid suitable for dielectric applications.
RSO-80 has a fire point exceeding the requirements of these documents and is within the IEC 1100 class with lowest heat of combustion. Silicone Transformer Oil presents a much lower fire hazard than other transformer fluids. It is difficult to ignite, but if ignited, it will produce less heat and smoke. It will virtually extinguish itself when external heat source is removed.
Silicone Fluids are exempt from Federal VOC regulations, including California (CARB) and OTC regulations. They are HAP-free and do not contribute to ozone-depletion and global warming. In addition, they meet RoHS Compliancy.
