- Product Introduction
Wedge type tension clamp H3 anchor clamp
The H3 fiber optic cable dead clampis engineered for securing round cables (4–7 mm diameter) and "figure-8" suspension cables with external load-bearing elements. Its modular design integrates a UV-resistant plastic body, polymeric wedges, and a hot-dip galvanized steel loop, enabling tool-free manual installation on utility poles via hooks or brackets. This clamp is also compatible with ADSS fiber optic cables, electrical conductors, and aerial self-supporting cables, making it ideal for diverse overhead line systems
This cable protection device achieves secure anchoring and reliable protection through innovative modular design. Its four-step standardized workflow-wedge-shaped positioning, cable precise insertion, adaptive clamping, and steel ring reinforcement-ensures zero damage to the cable sheath during installation.
Field tests demonstrate operational stability across -50°C to +150°C and pH 2–12 corrosive environments. The modular splicing technique reduced installation time for 2,000 anchor points from 15 to 6 days in a transmission line upgrade project.

Installation Technology.
During the installation phase, the fiber optic cable dead clampis structure automatically aligns the cable axis through mechanical guidance, dispersing initial anchoring stress.
The self-tightening wedge mechanism utilizes elastic components to dynamically compensate for thermal expansion or external tensile forces, maintaining local pressure below the sheath's tolerance threshold.
The steel ring insertion stage employs pre-stressed threaded locking technology, enhancing tensile strength by 40% and making it ideal for vibration-prone overhead line scenarios.
Performance and Application Value.
In extreme conditions (e.g., hurricanes, heavy impacts), the device prioritizes cable protection through multi-stage energy dissipation mechanisms.
Its core design features a high-ductility alloy steel body with a preset yield strength of 1.2–1.5 times the cable's breaking force, enabling absorption of over 80% of impact energy during overload.
As a critical component for power system disaster prevention, this device integrates mechanical optimization and material science breakthroughs, reducing failure rates while lowering maintenance costs. Its parameters fully comply with GB/T 12706.3-2020, offering innovative solutions for high-altitude and high-wind power transmission.
Application
Choose the plan that suits you best.
Terminal Tower Fixation
The JBG-2 anchor clamp secures ADSS cables at terminal towers, where the cable transitions from aerial to ground-based
infrastructure.
01
Angle Tower Support
Installed on towers with >25° angles, the clamp distributes mechanical loads evenly across the cable's diameter.
02
Long-Span Suspension
For spans exceeding 800 meters, the JBG-2 anchor clamp is paired with pre-twisted tension clamps to anchor cables mid-span.
03
Cable Entry to
Substations
At substation entry points, the clamp anchors ADSS cables transitioning from aerial to indoor conduits.
