Abstract

In a leadthrough for an electrical high voltage conductor through a wall which separates a process area from an ambient area, comprising a body of a dielectric high voltage resistant material, two axially adjacent geometric base structures are provided, a cylinder and a truncated cone having a smaller diameter end adjacent the cylinder so that the cylinder has a radial annular surface area adjacent the truncated cone, and the cylinder includes axially extending gas supply bores arranged uniformly distributed over the circumference of the cylinder and having exit openings at the radial annular face of the cylinder such that gas supplied to the gas supply bores at the ambient area end of the cylinder is discharged from the gas supply bores onto the outer surface of the truncated cone to form a gas envelope around the truncated cone.
