JIS C 2390-3:2020 PDF Download

JIS C 2390-3:2020 is a standard that specifically applies to modified esters derived from vegetable oils, which are used as insulating and heat exchange media in various electrical equipment, such as oil-impregnated capacitors, oil-filled cables, oil-immersed transformers, and oil circuit breakers. The standard sets out the requirements for these modified esters when they are in an unused state.

This standard is closely aligned with the International Electrotechnical Commission (IEC) standard IEC 62770:2013, which focuses on unused natural esters for transformers and similar electrical equipment. The relationship between JIS C 2390-3:2020 and IEC 62770:2013 is specified in terms of correspondence.

By implementing the guidelines set forth in JIS C 2390-3:2020, manufacturers and users of electrical equipment can ensure that the modified esters derived from vegetable oils meet the necessary criteria for environmental safety and performance. Adhering to this standard helps in promoting the use of readily biodegradable and sustainable insulating oils in the electrical industry.
