Hi Ian, Transformers ( 变压器) are not listed in the CCC Catalogue ( http://www.cnca.gov.cn/cnca/rdht/qzxcprz/rzml/images/20070123/995.htm) except the ones for welders (sub-item number, the second column, 46). However, GB 19212.x series standards for transformers are mandatory national standards. Transformers may have to demonstrate compliance with the GB 19212.x standards. Test reports should be enough to fullfil this requirement. I list several GB 19212 standards for your reference.
