Pole assembly with transition ring

A sealing arrangement for a pole assembly, said pole assembly comprising a base of substantially constant cross section, an upper mast of substantially smaller constant cross section and a cladding, a free end of said upper mast being inserted within a free end of said base so that a portion of said base overlaps said upper mast and said upper mast is fastened to said base, and said cladding surrounds said base, said sealing arrangement comprising a transition ring and a seal assembly, said transition ring surrounding a portion of said base and upper mast and said cladding at said free end of said base, said transition ring having an internal downwardly facing surface, and said seal assembly is disposed within said transition ring to seal between the external surface of said upper mast and said transition ring, said seal assembly comprising a sealing plate and a seal, said seal being disposed between said downwardly facing surface and said sealing plate, and the sealing action of said seal assembly is actuated by said sealing plate squeezing said seal.

A sealing arrangement for a pole assembly, said pole assembly comprising a tubular base, a tubular upper mast of smaller diameter inserted within a free end of said base and fastened thereto, and cladding surrounding said base, and wherein said sealing arrangement comprises a transition ring and a seal assembly used to seal the transition between said base and said upper mast, said transition ring surrounding a portion of said base and upper mast and said cladding at said free end of said base, said transition ring having an internal downwardly facing surface, and said seal assembly is disposed within said transition ring to seal between the external surface of said upper mast and said transition ring, said seal assembly comprising a sealing plate and a seal, said seal being disposed between said downwardly facing surface and said sealing plate, and the sealing action of said seal assembly is actuated by said sealing plate squeezing said seal such that it bulges inwardly to seal between the external surface of said upper mast and said transition ring, and wherein the friction between said seal and the external surface of said upper mast keeps transition ring in position.
