Problems solved by technology

[0011] The disadvantage of this method is that, although the mica-alumina tape is produced by the filtration method, the mica-alumina tape is subsequently connected to a strength-enhancing fibrous support by using an adhesive, which is usually filled with strength-enhancing fibers complex mesh
The thermal conductivity of the total system is limited due to the polymeric filling of the fiber composite mesh with a thermally non-conductive polymer

Embodiment Construction

[0031] The meshes shown are filled according to the prior art with a binding material which generally has poor thermal conductivity, since the recombination between the platelet-shaped particles and the fabric occurs only after the production of the (advantageously porous) particle composite according to EP11164882 It is done by attaching mesh fabric and adhesive.

[0032]The present invention relates to an insulating tape material, a method of manufacture and its use, in particular an insulating tape material for the manufacture of electrical insulating papers, such as mica paper, which are contained in heat-conducting insulating tapes, such as in used for high voltage insulation. The insulating tape material has fiber reinforcement by a fabric, the meshes of which are filled by a (preferably thermally conductive) particle composite.

Abstract

The invention relates to an insulating tape material, a method for production and usage thereof, particularly one for producing electrical insulation paper such as mica paper, which is contained in thermally conductive insulating tapes that are used for high-voltage insulation, for example. The insulating tape material has fibre reinforcement by means of a fabric, wherein the meshes of the fabric are filled by a particle composite which is preferably thermally conductive.

Description

technical field [0001] The invention relates to an insulating tape material, in particular for the production of electrically insulating papers, such as mica paper, which are contained in heat-conducting insulating tapes which are used, for example, for high-voltage insulation. Background technique [0002] Thermally conductive insulating tapes are used, for example, as main insulators to prevent overvoltage and / or breakdown of electric motors, high-voltage machines and / or (high-voltage) generators. [0003] Electrical machines, such as electric motors and generators, have electrical conductors, electrical insulation and a stator core. The purpose of the insulation is to electrically insulate the conductors from each other, from the stator core and from the surrounding environment. Under mechanical or thermal stress during machine operation, cavities can form at the interface between insulation and conductor or between insulation and stator core, in which cavities sparks ca...
