FIELD: electrical engineering; high-voltage suspension insulators. ^ SUBSTANCE: proposed high-voltage suspension insulator has metal cap, metal stick with head or any other bulge, and insulating part made of tracking-resistant silicone rubber; its head is press-fitted between metal stick and metal cap. Insulator also has disk-shaped member with hole that functions to join metal cap with insulating part. The latter is composite part incorporating more than one annular skirt. Insulating part skirts have concentric ribs. ^ EFFECT: enhanced operating reliability, simplified design, reduced cost. ^ 1 cl, 6 dwg |
