An anchoring clamp secures conductors and cables to overhead utility infrastructure such as power lines and telecommunication systems. The device firmly holds cables in place, preventing movement from tension, wind, or environmental factors to ensure stable network operation. Anchoring clamps provide dead-ending at span ends or directional changes with angles up to 90 degrees.
The clamps combine UV-resistant plastics, aluminum alloys, stainless steel, and galvanized steel components. Bodies use durable thermoplastic or aluminum, while wedges employ weather-resistant engineering plastics or nylon. Bail or fixing rings feature corrosion-resistant flexible stainless steel or hot-dip galvanized steel wire. This construction provides resistance to moisture, oxidation, frost, hurricanes, and UV radiation across temperature ranges from -60°C to +60°C.
These clamps accommodate cable diameters from 6 mm to 20 mm with breaking loads from 500 deciNewtons (daN) to 600 daN for standard models. Installation requires no specialized tools—users insert the wedge into the housing, position the cable, slide the wedge to secure it, and attach the guy wire loop to the pole using hooks, brackets, or cross arms. This method preserves cable insulation integrity and reduces installation time.
Applications include overhead power distribution networks, telecommunication lines, and fiber optic installations. The clamps secure All-Dielectric Self-Supporting (ADSS) cables, Figure-8 fiber optic cables, Fiber Reinforced Plastic (FRP) or Kevlar messenger lines, and low voltage aerial bundled cables on utility poles and building fasteners in rural, suburban, and industrial settings.
