Natural Ester Insulating Oil RAPO®


RAPO® Natural Ester Insulating Oil is an environmentally friendly, flame-retardant insulating oil derived 100% from renewable vegetable sources. Its performance has reached an international level that complies with IEC and IEEE standards. It is compatible with transformers across various voltage levels, and for voltage levels below 500kV in particular, it has a global export track record in regions such as Spain, Singapore, South Korea, Australia, and South America. Furthermore, it is suitable for applications in electrical equipment using coils and insulating equipment requiring liquid cooling.

This insulating oil offers outstanding environmental performance, flame retardancy, and safety, and its carbon emissions are only one-fifty-fifth (1/55) of those from mineral insulating oil. It contributes to extending the reliable service life of transformers and other insulating equipment and reducing the environmental impact.

The following benefits can be expected from RAPO® Natural Ester Insulating Oil:

  ・Enhancing the green and low-carbon level of the energy industry

  ・Fire prevention

  ・Improving environmental protection and mitigating the environmental risks associated with mineral-based insulating oil (hazardous waste)

  ・Extending the life of insulating materials and transformers

  ・Reducing life cycle costs
