TotalEnergies ISOVOLTINE BIO – Biodegradable Insulating Oil
ISOVOLTINE BIO is a rapidly biodegradable insulating oil based on thermally stable synthetic esters. It is an ecological alternative to mineral and silicone oils and is used as a cooling and insulating fluid in high-voltage applications such as transformers, converters, switches, and resistor regulators.
Product Advantages
• Excellent insulating performance
• Low viscosity for effective cooling
• Outstanding oxidation stability for long service life
• Biodegradability 72 % according to OECD 301 B
• Very high flash point (265 °C) reduces fire risk compared to mineral oil
• Up to 50 % from renewable raw materials
• Protects insulation paper due to hygroscopic (water-binding) properties
Typical Applications
• Cooling and insulating fluid in high-voltage systems
• Transformers
• Converters
• Switches and resistor regulators
