Φ660mm Nylon Sheave Stringing Block for OPGW & Fiber Optic Cables

Φ660mm Nylon Sheave Stringing Block: Ultimate Protection for OPGW & Fiber Optic cable stringing

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that the successful installation of delicate optical fiber cables, including OPGW (Optical Ground Wire) and various ADSS (All-Dielectric Self-Supporting) types, hinges on using stringing equipment that prioritizes cable integrity. The large diameter and sensitive outer jackets of these modern communication cables require specialized handling to prevent crushing, kinking, or abrasion. Our Φ660mm Nylon Sheave Stringing Block for OPGW & Fiber Optic Cables is a "Special block" meticulously engineered with a "Φ660mm nylon sheave" specifically "to string all sorts of optical fiber cable" with the utmost care and precision. This block ensures smooth, low-friction passage while providing unparalleled protection for your valuable fiber optic assets. As a prominent China manufacturer and exporter specializing in comprehensive one-stop supply for both overhead transmission line (OHTL) wire cable conductor tension stringing equipment and underground cable laying equipment, this specialized stringing block exemplifies our unwavering commitment to providing innovative, durable, and highly effective tools that ensure the long-term reliability and high performance of your critical fiber optic infrastructure.

The Φ660mm Nylon Sheave Stringing Block stands out due to its generous sheave diameter and the material choice. The large Φ660mm (26-inch) diameter of the sheave is crucial as it maintains a larger bending radius for the optical fiber cable, significantly reducing stress and preventing micro-bends that can cause signal loss. The nylon sheave is specifically selected for its inherent properties: it is lightweight, non-conductive, and, most importantly, non-abrasive. This ensures that the delicate outer jacket of OPGW, ADSS, and other fiber optic cables is protected from scratching, gouging, or crushing during tension stringing. The sheave runs on high-quality, sealed ball bearings, guaranteeing exceptionally smooth and low-friction rotation, which further protects the cable and contributes to efficient pulling operations. The robust frame, typically constructed from galvanized steel or high-strength aluminum alloy, provides the necessary structural integrity and universal attachment options for mounting on towers, poles, or cross-arms. By choosing Ningbo Changshi's Φ660mm Nylon Sheave Stringing Block, you invest in a critical component that ensures damage-free, efficient, and high-quality installation of all sorts of optical fiber cables, safeguarding your investment in communication infrastructure.

Product Features & Benefits:

• Optimal Cable Protection: The large Φ660mm (26-inch) diameter sheave maintains a wide bending radius, minimizing stress on delicate optical fibers and preventing micro-bends, kinking, and structural damage to OPGW and ADSS cables.

• Non-Damaging Nylon Sheave: Constructed from high-strength, non-abrasive nylon (or other specialized polymers), the sheave surface protects the sensitive outer jacket of fiber optic cables from scratches, cuts, and crushing during passage.

• Smooth, Low-Friction Operation: Equipped with precision-sealed ball bearings, ensuring exceptionally smooth, quiet, and low-resistance rotation, which reduces pulling tension requirements and protects the cable.

• Versatile for All Fiber Optic Cables: Specifically designed and suitable for stringing a wide range of optical fiber cables, including OPGW (Optical Ground Wire), ADSS (All-Dielectric Self-Supporting), and other delicate communication cables.

• Robust & Durable Construction: The sturdy frame is typically made from hot-dip galvanized steel or high-strength aluminum alloy, providing excellent corrosion resistance and structural integrity for demanding field conditions.

• Secure & Universal Attachment: Designed with secure mounting points (e.g., universal hangers, clevis fittings) for easy and safe attachment to towers, poles, or temporary structures.

• Reduces Installation Risks & Costs: By preventing cable damage during stringing, it significantly reduces the need for expensive repairs, splicing, or re-stringing, saving time and resources.

• Enhanced Operational Efficiency: The smooth operation and reliable performance contribute to faster, more controlled, and efficient cable installation.

• Non-Conductive Sheave: The nylon sheave material provides an added layer of safety by being non-conductive, an important consideration when working near live lines.

Product Applications:

Our Φ660mm Nylon Sheave Stringing Block is an indispensable tool for safe and efficient installation of all types of overhead fiber optic cables:

• OPGW cable stringing: Essential for guiding Optical Ground Wire (OPGW) smoothly and safely during tension stringing operations on transmission lines.

• Fiber Optic Network Expansion: Used in any project involving the aerial deployment of sensitive fiber optic communication cables on new or existing power infrastructure.

• Long Span & High Tension Stringing: Its large diameter and low-friction design are particularly beneficial for challenging long spans or projects requiring high pulling tensions.

• Critical Infrastructure Projects: Deployed in sensitive environments where cable integrity is paramount and damage must be strictly avoided.

• Any Application Requiring Ultimate Fiber Optic Protection: Applicable wherever delicate fiber optic cables need to be pulled through OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks with minimal risk of damage.

Technical Data Sheet (Example Specifications - please refer to specific model for exact data):

Note: It is crucial to select the correct stringing block size and sheave groove that is precisely compatible with the outer diameter of the optical fiber cable being strung. Always verify the block's Safe Working Load (SWL) meets or exceeds the expected cable tension during stringing. Regularly inspect the sheave for wear, cracks, or damage and ensure bearings run smoothly before each use. Please contact us for detailed datasheets for specific models and their exact specifications, compatible cable diameters, and load capacities.
