INSULATING TAPE FOR MAKING AN INSULATING SHEATH IMPREGNATED WITH A HEAT- CURING EPOXIDE RESIN/ACID ANHYDRIDE MIXTURE FOR ELECTRICAL CONDUCTORS

摘要

Electrical Tape for the preparation of an Insulating Sheath for Electric conductors, particularly for the bars or coils Winding of Electrical Machines.The Tape is impregnated with a Resin Composition and Hot Cross linkable epoxy acid anhydride and consisting in a laminar inorganic material resistant to PERFORATION DischargeThe type of lamellae or Thin layers of micaImplemented on a flexible substrate and is consolidated with the substrate and in a given case with a cover layer by a Binder containing an accelerant of the reaction.Culacion the composition of Resin ImpregnationForming the mixture of Binder system and a self Crosslinking accelerant to the curing temperature of the Resin; The Binder is composed of an Epoxy Resin cicloalifatica cicloepoxiGiven physiologically safe, modified by increasing molecular size, with epoxide equivalent 200 More,The rantes in addition products of compounds 1 - Ethyl piperazine or 1 - Methyl piperazine compounds with acrylate or methacrylate.
