Assembly Drawing of Reinforced Double Preformed Tension Clamp.
-Allows easy, convenient, and quick installation without the need for special tools; installation can be completed by a single person, significantly reducing construction time and cost.
-Installation quality can be visually inspected on-site without the need for special training or tools.
-The complete set includes outer and inner preformed wires, matching hardware fittings, grounding wires, and more.
-Reinforced double preformed tension clamps adopt a three-layer structure—comprising inner, middle, and outer preformed wires—which significantly enhances tensile strength and allows installation at any line angle without restriction.
-Guy Grip Dead End are mainly used for installing OPGW cables on tension towers, angle towers, and terminal towers.
-Guy Grip Dead End is used as the fixed ends of overhead transmission lines and OPGW cables.
-Bearing line tension at terminals or line angles.
