ABSTRACT:
An electrical insulator including a tube surrounded by an insulating sheath. The insulating sheath is composed of a filled, hardened, flexibilized, hydrophobic, cycloaliphatic epoxy resin containing from 25 to 75 percent by weight of mineral filler. The process for manufacturing this insulator includes the steps of installing the insulator tube or a precursor of the tube in an electrical insulator mold, feeding the filled unhardened hydrophobic cycloaliphatic epoxy resin in the mold so as to form the sheath, hardening the resin inserted in the mold so as to obtain the insulator, and extracting the insulator obtained from the mold.
