FIELD: electric engineering, in particular, explosion-proof electric equipment. ^ SUBSTANCE: waterproof pass isolator consists of conducting rod and porcelain isolating bushing, reinforced on the outside by metallic flange. At portions of conducting rod, positioned inside aforementioned isolation bushing, except the portion, reinforced by metallic flange, compensating bushings, tightly pressed to rod, are provided. Hollow between compensating bushings and isolation bushing (in ends of bushing), between conducting rod and isolation bushing (at the portion of porcelain bushing in area, reinforced by metallic flange) is filled with epoxide compound. ^ EFFECT: increased reliability and lifetime of waterproof pass isolator. ^ 1 dwg |
