ELECTRICALLY INSULATING MATERIAL, INSULATING PAPER AND INSULATING TAPE FOR HIGH-VOLTAGE ROTARY MACHINE Russian patent published in 2014 - IPC H01B3/02 

FIELD: chemistry.

SUBSTANCE: electrically insulating material for a high-voltage rotary machine consists of a base resin and powdered filler distributed in the base resin as the only filler, which is formed by plate-like aluminium oxide particles, wherein the powdered filler consists of particles with size of 0.002-150 mcm and volume ratio thereof ranges from 50% to 75%, preferably about 70%. The insulating paper for a high-voltage rotary machine contains said electrically insulating material. The insulating tape for a high-voltage rotary machine includes a carrier tape and an insulation paper tape, wherein the insulation paper tape is placed and attached onto the carrier tape.

EFFECT: improved electrically insulating material.
