5438,5440,5450 mica tape for motor,Glass Fiber+Mica Paper+Glass fiber
|
This tape is built up with mica paper as
base material and parallel glass fibers 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.

The tape adhesion must be distributed homogeneously without
bubble, delamination, impurity, rupture of mica paper, loosening of core, bad
shape, etc.

The length of mica tape is shown by its coil diameter. The
diameter of tape coil is 95mm±5mm or 115mm±5mm. The joints of each roll should
not be more than 2 pieces and the shortest length must be no less than
5M.
