CALMICA-FLEX ® SI 2726 consists of mica paper with aramide fibres impregnated with silicone resin and a glass cloth as carrier.  The insulation with with  CALMICA-FLEX ® SI 2726 shows good taping properties and very high thermal stability.  It remains flexible after heat treatment.   CALMICA-FLEX ® SI 2726 is compatible with solvent free silicon impregnating resins.

Applications

CALMICA-FLEX ® SI 2726 is used e.g. for endwinding  insulation in high voltage machines of thermal class 180 (H).  For copper strand conductor and main insulation of rotor windings CALMICA-FLEX ® SI 2726 is used as well as for pole coils and connections in traction motors up to thermal class 200 (C).  CALMICA-FLEX ® SI 2726 can be processed with or without an impregnation process with silicone resin
