JIS C 2390-2:2020 PDF Download

JIS C 2390-2:2020 is a standard that defines the requirements for natural esters, specifically vegetable oils, that are used as insulating and heat exchange media in various oil-filled electrical equipment. This standard ensures the quality and compatibility of these natural esters for applications such as oil-impregnated capacitors, oil-filled cables, oil-immersed transformers, and oil circuit breakers.

It is important to note that this standard aligns with the International Electrotechnical Commission (IEC) standard IEC 62770:2013, which addresses the same topic of unused natural esters for transformers and similar electrical equipment. This indicates that JIS C 2390-2:2020 is consistent with international standards, promoting harmonization and facilitating global acceptance of natural esters as suitable alternatives for electrical insulation in various equipment.
