Abstract
An integrated insulator sealing and shielding assembly includes a rubber housing having a plurality of radial weathersheds and a tapered end adjacent an endmost radial weathershed. A metal fitting is disposed adjacent to the endmost radial weathershed and receives the tapered end. A collar assembly is disposed at an upper end of the metal fitting and includes two apertures between an outer surface thereof and the rubber housing for receiving a sealant. At least one sealing surface, preferably four, is disposed between the collar assembly and a bottom end of the rubber housing for securing the connection therebetween.
Claims22
An insulator shielding assembly, comprising:
- a rubber housing having a plurality of radial weathersheds and a tapered end adjacent an endmost radial weathershed;
- a metal fitting disposed adjacent to said endmost radial weathershed and receiving said tapered end;
- a collar assembly disposed at an upper end of said metal fitting including at least one aperture between an outer surface thereof and said rubber housing;
- and
- at least one sealing surface disposed between said collar assembly and a bottom end of said rubber housing.
An insulator shielding assembly, comprising:
- a rubber housing having a plurality of radial weathersheds and a tapered end adjacent an endmost radial weathershed;
- a metal fitting disposed adjacent to said endmost radial weathershed and receiving said tapered end;
- a collar assembly disposed at upper end of said metal fitting including first and second apertures between an outer surface thereof and said rubber housing and a counterbore extending between said apertures;
- and
- first and second sealing surfaces disposed between said collar assembly and a bottom end of said rubber housing.
An insulator shielding assembly, comprising:
- a rubber housing having a plurality of radial weathersheds and a tapered end adjacent an endmost radial weathershed;
- a metal fitting disposed adjacent to said endmost radial weathershed and receiving said tapered end;
- a collar assembly disposed at an upper end of said metal fitting including first and second apertures between an outer surface thereof and said rubber housing and a counterbore extending between said apertures and adjacent said tapered end for creating first sealing surfaces with said rubber housing;
