ABSTRACT:
A clamp for an overhead line including a clamp body in which a first gripping groove for gripping the overhead line is formed; a clamp cap in which a second gripping groove for gripping the overhead line is formed and which is pivotably attached to the clamp body via a hinge unit; a fastening unit for fastening the clamp body and clamp cap in a manner enabling free opening and closing so that the overhead line is affixed between the first and second gripping grooves so as to be unable to move in an axial direction at the pivot position of the final fastening state; and an expansion unit for causing the clamp cap to stop at a position where it is forcibly kept open by a predetermined clearance from the clamp body against a fastening force given by the fastening unit so that the clamp body and the clamp cap are not located at the pivot position of the final fastening state and in addition so that a clearance is formed between the first and second gripping grooves and the overhead line and a method for attachment of the same.
