Heavy-Duty Crossarm-Mounted Stringing Block for OHTL Conductors

Heavy-Duty Crossarm-Mounted Stringing Block for Reliable Overhead transmission line (OHTL) Conductor Installation

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we are dedicated to supplying the essential and most reliable tools for constructing and maintaining robust power infrastructure. Our Heavy-Duty Crossarm-Mounted OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks are fundamental components meticulously engineered for the efficient, safe, and stable guiding of conductors during the tension stringing process on overhead transmission lines (OHTL) and distribution poles. 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 secure design, unwavering durability, and practical field performance.

The ability to securely mount stringing blocks directly onto a crossarm is critical for stability and precise conductor control, especially when dealing with various line angles, spans, and conductor types. Our crossarm-mounted blocks ensure that conductors are properly supported and guided, minimizing friction, preventing damage, and allowing for a controlled, smooth stringing operation. Their robust construction and reliable attachment mechanism make them an indispensable asset for power utilities and contractors worldwide.

Product Features & Benefits:

• Secure Crossarm Mounting: Specifically designed with integrated clamping or bolting mechanisms for direct, stable, and secure attachment to utility pole crossarms, ensuring rigidity and precise conductor guidance during stringing.

• Robust & Heavy-Duty Construction: Manufactured from high-strength galvanized steel or durable aluminum alloys, built to withstand significant tension loads, severe weather conditions, and continuous operational demands, guaranteeing extended service life.

• Smooth & Efficient Operation: Equipped with high-quality, sealed precision bearings that ensure exceptionally smooth and low-friction rotation, facilitating effortless conductor pulling and minimizing wear on both the block and the conductor.

• Superior Conductor Protection: Features a precisely engineered groove, often lined with non-abrasive materials like UMC (polyurethane) or resilient rubber, providing a gentle contact surface to protect the conductor from kinking, abrasion, or other costly damage.

• Versatile Conductor Compatibility: Available in various sheave diameters and groove profiles to accommodate a wide range of conductor types and sizes, from single wires to bundle conductors.

• Enhanced Stability: The direct crossarm attachment enhances overall stability during stringing, reducing sway and ensuring a more controlled and safer operation compared to suspended blocks.

• Corrosion Resistant: All exposed components are typically hot-dip galvanized or treated with durable powder coating, providing excellent protection against rust and environmental degradation, ensuring longevity.

Product Applications:

Our Heavy-Duty Crossarm-Mounted Stringing Blocks are indispensable for a wide range of overhead power line construction and maintenance projects:

• New Distribution & Transmission Line Construction: Essential for the initial stringing of conductors on new overhead routes where crossarm mounting is the preferred method.

• Re-conductoring & Line Upgrades: Ideal for replacing or upgrading existing conductors efficiently and safely, providing stable guidance at each pole.

• Angle Pole & Corner Installations: Crucial for managing conductor tension and direction changes around angle poles and line corners, ensuring a smooth path.

• Long Span & Difficult Terrain Stringing: Provides robust and stable support for conductors over challenging spans where consistent guidance is paramount.

• Utility Pole Work: Specifically designed for the common practice of mounting directly onto utility pole crossarms in distribution and sub-transmission systems.

• Maintenance & Repair: Critical for temporary support or re-stringing during routine maintenance or emergency repairs.
