Definitions
- the invention relates to an electrical insulation material and / or impregnating resin for the winding tape insulation and an insulation system, for example an insulation system for a rotating electrical machine, in particular a ⁇ tel or high voltage machine.
- EP 1 981 150 A2 describes a generator with a rotatable rotor and a stator arranged around the rotor.
- the stator has a rotationally symmetrically configured laminated core, wherein electrically conductive winding rods run in grooves on the laminated core.
- a winding head which connects the winding rods via connecting webs to a closed winding.
- An insulation system has the task electrical conductors, such as wires, coils and winding rods, permanently against each other and against the laminated core of the stator or to isolate the environment.

- Mica tapes are used in the form of mica paper.
- the cavities in the mica paper between the individual particles and / or strip folds are filled with the insulating material.
- the composite of impregnating resin and mica paper is hardened, forming the insulating material, which is then processed in the insulation system and provides the mechanical strength of the insulation system.

- it is endeavored to reduce the thickness of the insulation system, for example by about 20%.
- This inevitably leads to increasing electric field strengths in the insulation system from - again, for example, 3.5 kV / mm to 4.5 kV / mm and thus to an increased electrical see partial discharge activity.
- the commonly used insulation systems allow permanent operating field strengths of 3.5kV / mm with a technically possible lifetime of at least 20 years.
- Previously used carbon-based as base resins for electrical insulation and in particular as impregnating resins for winding tape insulation preferred epoxy resins which are in liquid form on a carbon-based (-CR 2 -) n _ return ⁇ grat all possible functional groups, for example also carry epoxy groups. These are reacted with hardener to a thermosetting plastic, which forms a casting and / or, for example, the impregnation of Wickelbandiso ⁇ lation.
