A fixed tension clamp 500 has a clamping mechanism 520 to clamp and release a wire W. When the clamping mechanism releases the wire, the fixed tension clamp is configured so that the wire contacts spaced rollers 530a, 530b either side of the clamping mechanism. The wire is in contact with spaced rollers in the released arrangement and the wire is able to move freely when a tension is applied. A constant tension is achieved without removing the wire from the fixed tension clamp and the clamping mechanism can be operated to clamp the wire without further manipulation of the wire to obtain consistent tension along the length of wire. The fixed tension clamp is suitable for use in overhead line equipment (OLE) on a railway, particularly where the wire is a contact wire and the claim is installed on a registration arm, or where the wire is a catenary wire and the claim is installed on a cantilever arm
