Abstract
A pressurized gas circuit-breaker pole includes a first enclosure or pole head having a first envelope with a first connecting flange including a circular orifice. The envelope contains a first mobile assembly terminating in a coupling member coaxial with the orifice. A second enclosure constituting an insulative column includes a second envelope having a second connecting flange with a circular orifice. The second envelope contains a second mobile assembly having a link for maneuvering the first mobile assembly and its end including complementary arrangements for coupling it with the coupling member. The connecting flange of each enclosure has an annular elastomer seal fixed to the corresponding connecting flange and through which the corresponding mobile assembly passes. The seal of each enclosure provides, during assembly of the flanges and coupling of the internal mobile assemblies, a sliding seal. The seal is broken on completion of assembly.
