This tape is built up with mica paper as base material and parallel glass fiber and polyester film on both sides as reinforcing materials bonded by binder into complex mica tape. It is mainly used for insulation materials of AC stator winding circle and flexible high voltage ground lead. It is able to be applied as pressurize safety tape for generator insulation. Owing to its high mica content, excellent electrical function, thin thickness as well as high tensile strength, the mica tape is becoming as an ideal insulation material.
1、外观 Appearance
粉云母带胶粘剂应分布均匀，不允许有气泡、分层、外来杂质、云母纸断裂、卷芯松
动、成形不良等现象。
The tape adhesion must be distributed homogeneously without bubble, delamination, impurity,
rupture of mica paper, loosening of core, bad shape, etc.
