This Part replaces GB/T 5020-2002 "is defined in the insulating material mica-based and general requirements." this section compared with GB/T 5020-2002 The main changes are as follows.

a) increase the "normative references";

b) delete the definition of mica injection;

c) increase the "soft mica after impregnation of porous materials" and "fire-resistant safety cables with a soft material mica";

d) delete the words "molded parts." this part is proposed by the China Electrical Equipment Industrial Association.

This part of the National Standardization Technical Committee of the insulating material (SAC/TC51) centralized.
