<p>The connection module comprises a tubular exterior structure (6) and a tubular interior structure (7) with couplings (9,10). A first part of the coupling (9) comprises a ferrule with an annular region (17) with a rounded surface. This faces a second annular zone (18) which includes protuberances (16). The two annular zones (17,18) form a spark gap to eliminate over-voltages. The connection module for a high tension line using gas isolation comprises a tubular exterior structure (6) and a tubular interior structure (7) provided with couplings (9,10) and an intermediate positioning structure (11). A first part of the coupling (9) within the tubular structure comprises a cylindrical ferrule within which the end of the tubular conductor may be fitted. The ferrule has, at its end, a first annular region (17) with a rounded surface. This faces a second annular zone (18) which includes protuberances (16). The two annular zones (17,18) are situated at a distance from the intermediate structure (11) are arranged to form a spark gap for elimination of over-voltages between the conductor (3) and an envelope (4).</p> |
