Abstract (en)
[origin: EP0735555A2] The invention relates to a high-voltage circuit breaker, the main current path of which is made of tubing (17, 18, 22) of a plastically machinable metallic material, preferably copper or a copper alloy. The connection flanges (11, 12) of the circuit breaker are fixed to the respective current-carrying metal tubes by rolling out one end portion of the tubes into a groove (25, 26) in the respective flange (11, 12). The current transfer between the tube and the flange is ensured with the aid of a resilient contact member (27, 28) arranged in the groove. <IMAGE>
