Materials for main insulation of insulating systems VPI

Materials for main insulation of insulating systems VPI

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® 315.42 0,13 160 mica, polyester foil   standard tape for high-voltage coils
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.

Material Samicapor® for silicone resin 3551

 

Name: Type: Thickness mm: Samica® contents g/m2: Structure: Properties: Applikations:
Samicapor® 366.85 0,12 113 7 g/m2 aramid fibers, 32 g/m2 glass fabric, silicone resin mechanical very strength for traction machines to temperature class C
Samicapor® 366.86 0,11 113 7 g/m2 aramid fibers, 23 g/m2 glass fabric, silicone resin mechanical very strength for traction machines to temperature class C
Samicapor® 366.87 0,14 120 without  aramid fibers, 32 g/m2 glass fabric, silicone resin mechanical very strength,unexpensive  for traction machines to temperature class C
Samicapor® 366.88 0,11 120 without aramid fibers, 23 g/m2 glass fabric, silicone resin mechanical strength,unexpensive,alternative to 366.86 for traction machines to temperature class C
