The wire clamp is composed of a rubber clamp block, a pre-twisted wire and a cast aluminum casing. 1. Enhance the rigidity of the cable hanging point and increase the radius of curvature. The single-line clamp can meet the 30° steering angle, and the double-line clamp can meet the 60° steering angle. 2. It can be ensured that the cable is not subject to large bending stress near the outlet of the wire clamp, so as to avoid local mechanical damage causing strand break or wire breakage.
