To create insulators in electrical engineering
On the basis of epoxy resins, electrical insulating compounds for hot and cold curing are made, which are compositions of epoxy resin, hardener, filler and plasticizer. These compounds are moisture resistant and can withstand prolonged heating up to 120-130 ° C. They are used for filling loop coils, transformers, chokes, cementation of coil turns in electrical machines, gluing high-voltage porcelain insulators, electrical insulation of wire junctions, etc. Fillers in the preparation of compounds are fibrous and powdery materials glass fibers, silicon dioxide, etc.
