Abstract
An improved insulating sheath for an electrical conductor, which is impregnated with a hardenable impregnating resin and afterwards hardened, has alternating layers of porous support and thermostable plastic foil support tapes of inorganic sheet type insulating material. The two tape multiple layered sheath gives increased dielectric strength and heat resistance without impairing resin impregnation capacity.
