[origin: US6051796A] PCT No. PCT/EP95/02699 Sec. 371 Date Jan. 29, 1997 Sec. 102(e) Date Jan. 29, 1997 PCT Filed Jul. 7, 1995 PCT Pub. No. WO96/04667 PCT Pub. Date Feb. 15, 1996An electric high-voltage insulator made from plastic comprises at least one glass fiber rod (1), at least one shield covering (2) made from silicone rubber which surrounds the glass fiber rod (1) and has concentric bulges (3) arranged along the longitudinal axis and bent in the shape of sheds in such a way that they form a convex top side and a concave or flat underside, as well as metal fittings (5) on both insulator ends. In this case, the bulges bent in the shape of sheds have at least one groove (4) on the underside preferably with a minimum depth of 1 mm.
