China's hydraulic oil filter oil quality standard
2018/5/17 Viewers:
China's oil standards are currently divided into four levels: international standards (such as ISO, IEC standards), national standards (code named GB), professional or industry standards (code named ZB, such as DL, SY, etc.), enterprise standards (code named QB) and so on.
The state stipulates that the new oil products are made up of new oil standards by manufacturers such as the oil ministry and the Petrochemical Corporation, and the operating oil is made by the use department (such as the Ministry of electricity) to establish the oil quality standards in operation. The criteria are based on the nature of crude oil, the technical level of refining, and the requirements of the use department.
what are the standards for new insulating oil in China?
Oil Standards (either new oil or running oil standards) are not invariable. In general, the oil quality standards should be revised according to new requirements for oil quality standards in the 5~10 years. Therefore, it is not easy to introduce the specific content of the standard. It only introduces the code and name of the standard so that it can be consulted in the work. (1) the standard of transformer oil. The new transformer oil in China is divided into three grades according to its freezing point: DB - 10.DB - 25, DB - 45. Its code name is GB2536 - 90, that is, the national standard of transformer oil. (2) ultra high voltage transformer oil: the code name is SH0040-91.
