940mm Large Capacity Stringing Block: Precision Engineering for Optimized OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing in Demanding OHTL Projects

On behalf of Ningbo Changshi Electric Power Machinery Manufacturing Limited, a prominent China manufacturer and global exporter specializing in comprehensive tools and equipment for power lines, substations, electrical construction, and maintenance, we are pleased to introduce our robust 940mm Large Capacity Stringing Block. This indispensable piece of equipment is expertly designed to manage the complexities of modern overhead transmission line (OHTL) construction, especially for projects involving significant conductor sizes and intricate multi-bundle configurations in Ultra-High Voltage (UHV) and High Voltage Direct Current (HVDC) systems.

The generous 940mm (approximately 37 inches) diameter of this stringing block is strategically engineered to provide an optimal bending radius for conductors. This crucial design feature minimizes bending stress and prevents potential damage to the outer strands or core of valuable single or bundled conductors as they are pulled across expansive spans and intricate structures. Built with high-strength materials and precision-engineered components, Ningbo Changshi's 940mm Large Capacity Stringing Block ensures exceptionally low friction, unwavering stability, and flawlessly smooth passage of conductors. This commitment to quality translates directly into enhanced operational efficiency, reduced risk of costly conductor damage, and improved long-term reliability for your power infrastructure projects, making it a cornerstone for efficient and safe stringing.

Product Features & Benefits:

The Ningbo Changshi 940mm Large Capacity Stringing Block is a testament to our precision engineering, designed for superior conductor protection, robust performance, and enhanced operational efficiency.

• Optimal Conductor Bending Radius (940mm Diameter): The ample 940mm sheave diameter ensures a gentle curve for large-diameter conductors and multi-bundle arrangements, significantly reducing bending stress and safeguarding the conductors from deformation, kinking, and surface damage during the stringing process.

• High Capacity for Bundle Conductors: Features a deep, precisely machined groove, often with a specialized lining (e.g., durable aluminum alloy or high-density polyurethane), designed to securely accommodate multiple conductors within a bundle (e.g., 4x, 6x bundles), ensuring smooth and synchronized payout.

• Robust & Durable Construction: Manufactured from premium-grade, high-strength aluminum alloy for the sheave and a heavy-duty galvanized steel or specialized aluminum alloy frame. This construction ensures exceptional strength, resilience against impact, and long-term durability in demanding field conditions.

• Low-Friction Precision Bearings: Equipped with high-quality, sealed ball or tapered roller bearings that provide ultra-low rotational friction. This facilitates incredibly smooth conductor movement, reduces pulling tension requirements, minimizes wear on the rope, and significantly extends the lifespan of the block itself.

• Secure Conductor Retention: Features a strong and reliable locking mechanism (e.g., heavy-duty spring-loaded lock pin with a secondary safety latch) that ensures the conductor or pulling rope remains securely seated within the block's groove throughout the stringing operation, even under dynamic loads or adverse weather.

• Corrosion and Weather Resistance: Frame components are either inherently corrosion-resistant or treated with robust protective coatings (e.g., hot-dip galvanization, anodization) to withstand harsh environmental conditions, including moisture, salt, and extreme temperatures, ensuring long-term reliability.

• Versatile Mounting Options: Designed with robust attachment points (e.g., Swiveling eye, clevis fittings) to provide flexible and secure mounting to various tower structures, cross arms, or temporary supports, allowing for optimal alignment with the stringing path.

• Ease of Maintenance: Engineered for accessibility, allowing for straightforward inspection, cleaning, and lubrication of critical components like bearings, which contributes to extended operational life and consistent performance.

Product Applications:

Our 940mm Large Capacity Stringing Block is an essential tool for a wide range of demanding power transmission projects:

• UHV & HVDC transmission line Construction: Indispensable for the installation of large single conductors and complex multi-bundle conductor configurations on ultra-high voltage and high-voltage direct current lines.

• Long-Span Stringing: Ideal for applications across major rivers, deep valleys, or mountainous terrains where minimizing conductor sag, controlling tension, and ensuring precise conductor handling over extensive distances are critical.

• Heavy Conductor & Bundle Stringing: Perfectly suited for handling the heaviest and largest conductor types, including ACSR, AAAC, and high-temperature low-sag (HTLS) conductors, as well as multi-conductor bundles.

• Sensitive Conductor Installation: Provides superior protection for delicate or high-value conductors, such as OPGW (Optical Ground Wire) or those with specialized coatings, preventing costly damage.

• High-Tension Stringing Operations: Designed to perform flawlessly under the significant loads and precise tension control required by modern tension stringing methods.

• Grid Expansion & Upgrade Projects: A key component for new power infrastructure development and the re-conductoring of existing lines, contributing to enhanced grid capacity and reliability.
