Abstract
An electrical insulating composition comprises a hydrocarbon oil having incorporated therein from 0,001 to 1% of one or more aliphatic amines having the formula R1NH2, R1NHR2, R1NR2R3 or R1NHR4NH2 wherein R1 is an aliphatic hydrocarbon group having from 8 to 20 carbon atoms, which may contain one or more olefinic bonds, R2 and R3 are aliphatic hydrocarbon groups containing from 1 to 20 carbon atoms, each of which may contain one or more olefinic bonds, and R4 is a difunctional aliphatic hydrocarbon group having from 1 to 4 carbon atoms, the composition as a whole having a power factor (tan delta) of not more than 0,005. The base oil may be prepared from a naphthenic base mineral oil by solvent extraction, acid treatment and/or absorbent earth treatment. Suitable amines include hexadecylamine, didodecylamine, N,N1-dimethyl-octadecenylamine, N-amino propyloctadecenylamine, and mixture of amines from tallow or soya bean or coconut oil. A copper deactivator such as disalicylidene-ethylene-diamine may be added. The compositions may also contain colophony, hydrocarbon waxes or polyisobutylene. The compositions may be used to impregnate cables and capacitors.
