100kN Bolt-Type Earthwire Grip for Long Span Steel & Aluminum Stranded Cables

100kN Bolt-Type Earthwire Grip: Unyielding Strength for Long-Span Steel & Aluminous Stranded Earthwire Construction on OHTL

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that long-span overhead transmission line (OHTL) construction presents unique challenges, particularly when dealing with the high tensions and critical safety requirements of earthwires. Our 100kN Bolt-Type Earthwire Grip is a heavy-duty, meticulously engineered tool specifically designed to provide an exceptionally powerful, fixed, and secure mechanical grip on both steel stranded and aluminous (aluminum) steel stranded earthwires, especially for demanding long-span applications. As a prominent China manufacturer and exporter, we offer comprehensive one-stop supply for a wide array of tools and equipment for power lines, and this high-capacity earthwire grip exemplifies our unwavering commitment to extreme load performance, precision engineering, and unparalleled reliability for ensuring the success and safety of your most critical OHTL projects.

Earthwires, serving as vital lightning protection and sometimes carrying optical fibers (OPGW), must be installed with absolute precision and security, especially over extended distances. The "bolt type" fastening mechanism of this grip offers a superior, non-slip mechanical connection that can be precisely tightened to an exact force. This ensures an unyielding hold that is critical for managing the high tensions encountered in long-span construction. With a robust 100kN (10-ton) working load limit, this grip is perfectly suited for handling the heavy and taut ground wires used in major transmission projects, providing engineers and linemen with the confidence needed for safe and efficient operations, while effectively preserving the integrity of the earthwire material.

Product Features & Benefits:

• Exceptional 100kN Working Load Limit (WLL): Designed and rigorously tested to safely handle massive tension forces up to 100 kilonewtons, making it ideal for the heaviest earthwires and most challenging long-span applications.

• Robust Bolt-Type Mechanical Fastening: Features a heavy-duty bolt and nut system that provides a positive, controlled, and unyielding mechanical clamp, ensuring maximum slip resistance and secure long-term holding.

• Versatile for Steel & Aluminous Stranded Earthwires: Precision-engineered jaws are specifically designed to effectively grip both steel stranded and aluminous steel stranded earthwires, accommodating common ground wire compositions.

• Optimized for Long-Span Construction: Its high WLL and secure bolt-type grip are perfectly suited for managing the extreme tensions and prolonged holding requirements of earthwires over long spans (e.g., river crossings, valleys).

• Superior Wire Protection: The design ensures that gripping force is distributed uniformly across the wire, minimizing localized stress points and preventing damage (e.g., crushing, kinking, abrading) to the strands, thus preserving wire integrity.

• Extreme Durability & Strength: Manufactured from premium, high-strength forged alloy steel, meticulously heat-treated for maximum wear resistance and an extended service life in severe operating conditions.

• Reliable & Controlled Performance: Allows for precise application of clamping force, providing consistent and predictable performance during critical sagging, tensioning, and holding operations.

• Corrosion Resistance: All components are treated with advanced galvanization or durable protective coatings, providing exceptional resistance against rust and environmental degradation, crucial for outdoor use.

Product Applications:

Our 100kN Bolt-Type Earthwire Grip is an indispensable tool for a wide range of critical operations involving earthwires on overhead transmission lines, particularly those with long spans and high tensions:

• Long-Span Earthwire/OPGW Stringing: Absolutely crucial for pulling, tensioning, and sagging high-strength steel or aluminous earthwires, especially over extended distances like river or valley crossings.

• High-Tension Ground Wire Sagging: Provides the necessary holding power and precise control for accurately achieving the exact sag parameters on major transmission lines.

• Earthwire Splicing & Dead-ending: Used to securely hold earthwires during critical splicing, repair, or termination processes, providing a stable and safe working platform.

• Heavy Duty Grounding & Bonding: Can be used in substation construction for securing large grounding cables where high mechanical integrity is required.

• Transmission Tower Earthwire Installation: Ideal for managing and securing earthwires at various points during tower erection and line installation.

• Any Project Demanding High Load & Secure Earthwire Holding: The go-to grip for scenarios where maximum security, load capacity, and earthwire integrity are paramount.
