Inlet screen for a hydropower plant

An inlet screen adapted to be arranged at the water inlet (8) of a hydropower plant (2), comprising a plurality of elongated bars (20), said bars (20) being separated by a distance holding means (22), each elongated bar (20) having in its elongation a proximal portion (26a) and a distal portion (26b), and in a cross-section an upstream region (35a) and a downstream region (35b), at least one of said bars (20) defining a first space (36;

• 36a) extending along at least a portion of an extension of said bar in a direction of elongation of said bar (20), said first space (36;
• 36a) being defined in either of the upstream region (35a) and the downstream region (35b), said elongated bar having an intermediate portion (38a), said intermediate portion (38a) being elongated and extending along the direction of elongation of the bar (20) from the proximal portion (26a) of said bar (20) to the distal portion (26b) of said bar (20) between the upstream region (35a) and the downstream region (35b), said bar (20) being provided with an electric heating means (31), said electric heating means (31) comprising at least one electric heating member (37) being introduced into said first space (36;
• 36a) wherein the cross-section of at least one of said bars has a substantially aerodynamic profile.
