PA 2000 Tension Clamps

PA 2000 Tension Clamps

Engineered for extreme-span aerial installations, the PA 2000 tension clamp supports a 2,000 kg working load, suitable for river crossings (1 km+ spans), deep valleys, mountainous terrain, and high-wind coastal zones. The quad-bolt tension distribution system uses four compression bolts arranged symmetrically around the cable to apply uniform radial force, preventing ovalization of fiber tubes and reducing the risk of microbending losses. The heavy-duty galvanized steel body features reinforced ribs and thickened walls to resist deformation under maximum load. Neoprene grip liners are pre-molded with a precision groove pattern that matches the cable's outer sheath, maximizing friction without excessive compression. The PA 2000 is also used for steel messenger wire dead-ends on long-span distribution lines and for anchoring submarine cable landings where cable enters underground duct. Installation requires a torque wrench to ensure even bolt tightening across all four fasteners.
