The pole includes includes a first enclosure (1) or pole head including a first envelope (2) including a first connecting flange (6) including a circular orifice (5). The envelope contains a first mobile assembly (3) terminating in a coupling member (4) coaxial with the orifice (5). A second enclosure (13) constituting an insulative column includes a second envelope (14) including a second connecting flange (17) including a circular orifice (20). The second envelope (14) contains a second mobile assembly (15) consisting of a link for maneuvering the first mobile assembly (3) and its end including complementary arrangements for coupling it (16) with the coupling member (4). The connecting flange of each enclosure (1,13) is fitted with an annular elastomer seal (10, 21) 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 along the respective mobile assemblies (3, 15). The seal along the mobile assemblies is broken on completion of assembly by reversible and automatic deformation of the annular elastomer seal to establish communication between the two enclosures (1, 13).

Le Pôle comporte une première enceinte (1) dite tête de pôle comprenant une première enveloppe (2) comportant une première bride de liaison (6) ayant un orifice circulaire (5), ladite enveloppe contenant un premier équipage mobile (3) se terminant par un organe d'accouplement (4), coaxial audit orifice (5), et une seconde enceinte (13) constituant une colonne isolante comportant une seconde enveloppe (14) comprenant une seconde bride de liaison (17) comportant un orifice circulaire (20), ladite seconde enveloppe (14) contenant un second équipage mobile (15) consistant en une bielle de manoeuvre dudit premier équipage mobile (3) et son extrémité comportant des moyens complémentaires d'accouplement (16) avec ledit organe d'accouplement (4), et est caractérisé en ce que la bride de liaison (6, 17) de chaque enceinte (1, 13) est équipée d'un joint élastomère (10, 21) annulaire, fixé à la bride de liaison correspondante et traversé par l'équipage mobile correspondant, ledit joint de chaque enceinte assurant, pendant l'assemblage des brides et l'accouplement des équipages mobiles internes, une étanchéité coulissante le long de l'équipage mobile respectif (3, 15) et des moyens prévus pour casser l'étanchéité le long desdits équipages mobiles en fin d'assemblage, par déformation réversible et automatique dudit joint élastomère annulaire, afin d'assurer la communication entre les deux enceintes (1, 13).
