3 技术要求
This standard adopts specification IIA of IEC 296-82 Mineral Insulation Oils for Transformer and in Oil Switch by reference.
1. Subject Content and Application Scope
This standard specifies specifications for transformer oils which are produced by using petroleum distillate as raw material and then refined before adding antioxidant, and which have favorable insulativity, oxidative stability and cooling property.
Products covered in this standard are applicable to transformer of 330kV and below, as well as to electrical equipments having similar requirements.
The products are classified into three designations 10, 25 and 45, according to different low temperature properties.
