Abstract
The utility model discloses a grade C organosilicon polyimide membrane glass mica paper tape, which comprises a mica paper layer and a corona resistant polyimide membrane layer and an electrician non-alkali glass cloth which are respectively arranged on both sides of the mica paper layer. Definite heat resistant organosilicon adhesive layers are respectively adhered between the mica paper layer and the corona resistant polyimide membrane layer, and between the mica paper layer and the electrician non-alkali glass cloth. The grade C organosilicon polyimide membrane glass mica paper tape has the advantages that the mica content is high, the corona resistant performance is excellent, no low molecular content is generated after solidifying, the cost is low, and the insulation entirety and the service life can be improved, and the grade C organosilicon polyimide membrane glass mica paper tape is a corona resistant insulating material with excellent performance; simultaneously, the manufacturing technique is basically identical with the normal mica tape, which is easy to be operated, and the mass production can be realized on normal compound machine equipment.
Description
Technical field
The utility model relates to a kind of C level organic silicon polyimide film glass mica paper tape, and it is applicable to, and the C level is high temperature resistant, variable-frequency motor, electrical apparatus insulation field.
