Fabricated Large Diameter Stringing Block for Efficient Overhead transmission line (OHTL) Conductor Installation

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we specialize in providing robust and reliable equipment for the demanding world of power line construction. Our Fabricated Large Diameter OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks are meticulously designed to ensure the smooth, safe, and efficient installation of conductors on overhead transmission lines (OHTL). As a prominent China manufacturer and exporter, we offer a comprehensive one-stop supply for all your electrical construction and maintenance needs, and these Stringing Blocks exemplify our commitment to quality, durability, and practical design.

These large diameter stringing blocks are essential components for any significant OHTL project, minimizing friction and preventing damage to conductors during the tension stringing process. Unlike cast versions, our fabricated design allows for optimized strength-to-weight ratios and enhanced versatility, making them ideal for heavy-duty applications where a large bending radius is critical for conductor integrity.

Product Features & Benefits:

  • Optimized for Large Conductors: The large diameter wheel is specifically designed to handle a wide range of conductor sizes, including bundle conductors, providing a smooth bend radius that minimizes stress and potential damage.

  • Robust Fabricated Construction: Built from high-strength steel or aluminum alloys through a precision fabrication process, offering superior structural integrity and durability compared to traditional casting methods. This also allows for easier repair and customization.

  • Smooth & Efficient Operation: Equipped with high-quality, sealed precision bearings that ensure minimal friction and exceptionally smooth rotation, enhancing efficiency and reducing the effort required during stringing.

  • Conductor Protection: The carefully designed and often rubber-lined or polyurethane-lined groove ensures a gentle contact surface, preventing kinking, scratching, or other damage to the conductor, thereby preserving its integrity.

  • Versatile Mounting & Attachment: Designed with flexible mounting options (e.g., universal hangers, single/double pole attachments) to suit various tower configurations and stringing setups.

  • Corrosion Resistance: Typically finished with hot-dip galvanization or durable powder coating, providing excellent protection against corrosion and extending the lifespan in harsh outdoor environments.

Product Applications:

Our Fabricated Large Diameter Stringing Blocks are indispensable for a variety of overhead transmission line projects, including:

  • New OHTL Construction: Essential for the initial stringing of single and bundle conductors on new power line routes.

  • Transmission Line Upgrades & Re-conductoring: Ideal for replacing or upgrading existing conductors with larger, higher-capacity cables.

  • Medium to High Voltage Projects: Suitable for a broad spectrum of voltage levels where efficient and safe conductor handling is required.

  • Challenging Topographies: Their robust design and smooth operation make them reliable for use in diverse and demanding geographical conditions.
