Materials for main insulation of insulating systems VPI (vacuum-pressure impregnation)
Absorptive tapes Samicapor® forms with already mentioned solventfree resins for technology VPI main components of long-term tested and tried insulating systems VPI of company VonRoll. Other materials, which are used for insulating systems e.g. materials for protection against partial and gliding discharges,materials for the reinforcement of thread bundles etc.,must endure with other materials of insulating system and must be selected very carefully.
Materials Samicapor® for insulating system Samicabond® with unsaturated polyesterimid resin 3308 / 3309
Name: | Type: | Thickness mm: | Samica® contents g/m2: | Structure: | Properties: | Applikations: |

Samicapor® | 366.58 | 0,15 | 160 | mica,glass fabric | standard tape for high -voltage coils | |
Samicapor® | 366.53-01 | 0,12 | 120 | mica,glass fabric | for the highest applikations,high el. strength | traction coils |
Samicapor® | 374.04 | 0,18 | 160 | mica, polyester felt on the free side of Samica | very suitable for hand manufacture | cover tape for end of coils,insulation of leads of wires |
Materials Samicapor®with accelerator for epoxy resin 3407
Name: | Type: | Thickness mm: | Samica® contents g/m2: | Comment: | Structure: |
Samicapor® | 315.33 | 0,13 | 160 | unexpensive,flexible tape for rated voltage to 11 kV | mica, polyester foil |
Samicapor® | 366.55-10 366.55-20 | 0,15 | 160 | standard tape for high-voltage coils to highest rated voltages | mica,glass fabric |
Samicapor® | 374.15 | 0,18 | 160 | cover tape for ends of coils,insulation of leads of wires,suitable for hand manufacture | mica, polyester felt on the free side of Samicy |
Material Samicapor® for catalised epoxy resin
For these insulating systems VPI are suitable same materials as for insulating system Samicabond®, because these mica materials don't contain the accelerator.
