Insulating paper tubes for electrical conduits and other uses, essentially characterized by being formed by two or more superposed layers formed by strips of paper impregnated with an insulating composition based on tar, asphalt and other suitable matter, and wound on themselves spirally or in another form, said tube having, externally, a series of transverse grooves that produce superficial undulations obtained by molding or compression and that give the tube resistance and a certain flexibility to bend it in the desired shape.
