We find a large class of new supersymmetric black strings from five-dimensional gauged supergravity coupled to five vector multiplets with gauge group. These solutions have near horizon geometries of the form for being a two-sphere or a hyperbolic space There are four supersymmetric vacua with and supersymmetries. By performing topological twists along with and gauge fields, we find a number of fixed points describing near horizon geometries of black strings in asymptotically spaces. Most of the solutions take the form of with only one being preserving symmetry. We also give the corresponding black string solutions interpolating between asymptotically locally vacua and the near horizon geometries. There are a number of solutions flowing from one, two or three vacua to an fixed point. These solutions can also be considered as holographic RG flows across dimensions from and SCFTs in four dimensions to two-dimensional SCFTs with or supersymmetry.
