The high-voltage metal-clad substation element comprises at least one circuit-breaker connected electrically and mechanically to at least one set of busbars ( 3, 4 ) extending along an axis (D) that extends transversely to the longitudinal axis (AX) of the circuit-breaker. The metal case ( 1 ) is fixed to the ground via a hinge which allows the case to tilt slightly when said set of busbars ( 3, 4 ) expands along said transverse axis (D). This configuration makes it possible to omit or to reduce the use of axial bellows on the set of busbars, thereby reducing the cost of manufacturing the metal-clad substation. Advantageously, in association with the hinge, the metal case is designed to have some flexibility to reduce mechanical stresses when the set of busbars expands.
