Parallel Jaw Earthwire Grip for OPGW & Ground Wire Protection

Parallel Jaw Earthwire Grip: Unparalleled Protection and Secure Holding for OPGW & Ground Wires in Overhead transmission line (OHTL) Construction

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we are acutely aware that the integrity of ground wires, especially sensitive Optical Ground Wire (OPGW), is paramount during all phases of power line construction. Our Parallel Jaw Earthwire Grip is a highly specialized, meticulously engineered tool designed to securely and uniformly clamp onto ground wires without causing radial deformation or damage. Unlike traditional grips that may exert uneven pressure, this innovative parallel gripping mechanism ensures a consistent, gentle yet firm hold, crucial for the delicate fibers within OPGW or the precise lay of stranded earthwires. As a prominent China manufacturer and exporter, we offer a comprehensive one-stop supply for a wide array of tools and equipment for power lines, and this parallel grip exemplifies our unwavering commitment to precision protection, advanced design, and reliable performance for safeguarding your critical assets on OHTL projects.

Earthwires, which provide vital lightning protection and sometimes integrated fiber optic communication (OPGW), demand tools that prevent any form of deformation or crushing. The "parallel jaw" design ensures that the gripping surfaces close evenly, exerting uniform pressure along the length of the clamped section. This prevents stress concentrations, kinking, or slippage that could compromise the electrical or optical properties of the wire. This grip is indispensable for handling valuable OPGW, where fiber integrity is non-negotiable, and for other stranded earthwires where maintaining their structural lay is important for long-term performance.

Product Features & Benefits:

• Parallel Jaw Mechanism: The core innovation, ensuring that the gripping jaws close in parallel, providing uniform, non-deforming pressure across the entire clamped surface of the earthwire or OPGW.

• Optimal OPGW & Wire Protection: Specifically designed to prevent radial compression, crushing, or damage to delicate internal optical fibers in OPGW, and to maintain the lay of stranded conductors, extending their service life.

• Secure & Non-Slip Hold: Delivers an exceptionally firm and reliable grip that increases proportionally with tension, ensuring no slippage even under significant pulling forces.

• High Holding Capacity: Engineered from high-strength forged alloy steel, heat-treated for superior durability and wear resistance, capable of withstanding the substantial tensile forces involved in earthwire operations.

• Quick & Easy Application: Designed for straightforward and efficient attachment and release, enhancing operational efficiency and reducing manual effort.

• Robust & Durable Construction: Built to endure the continuous demands of field use and harsh environmental conditions, guaranteeing long service life and consistent performance.

• Corrosion Resistance: Components are typically hot-dip galvanized or coated to provide excellent protection against rust and environmental degradation.

• Versatile Compatibility: Available in models compatible with specific diameter ranges of various steel, aluminum, and OPGW earthwires.

Product Applications:

Our Parallel Jaw Earthwire Grip is an indispensable tool for a wide range of operations involving ground wires on overhead transmission lines, particularly those with OPGW or sensitive stranded earthwires:

• OPGW Stringing & Tensioning: Absolutely crucial for safely pulling, tensioning, and sagging OPGW without jeopardizing its integrated optical fibers.

• Earthwire Installation & Sagging: Provides precise and damage-free handling of all types of stranded steel and aluminum earthwires during installation.

• Maintenance & Repair of Ground Wires: Essential for securing earthwires during splicing, re-tensioning, or other repair activities where wire integrity must be maintained.

• Conductor Positioning & Holding: Used to temporarily hold and guide earthwires during various phases of overhead line construction.

• River/Valley Crossing & Long Span Work: Offers reliable, non-damaging gripping for high-tension earthwire installations over challenging terrains.

• Any Project Demanding Wire Integrity: A vital tool for ensuring the structural and communication integrity of ground wires across the power grid.
