Heavy-Duty Terminal Tackle Block for OHTL Conductor Tensioning & Sagging

Heavy-Duty Terminal Tackle Block: Robust Tensioning for Precision Conductor Sagging in Overhead transmission lines (OHTL)

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we understand that the final, precise tensioning of conductors at terminal or anchor poles is a critical phase demanding exceptional strength, control, and reliability. Our Heavy-Duty Terminal Tackle Block is a specialized, meticulously engineered tool designed for applying significant force to tighten conductors to their exact specified sag and tension on overhead transmission lines (OHTL). 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 robust tackle block exemplifies our unwavering commitment to extreme load capacity, precise control, and reliable performance for achieving optimal line integrity.

Terminal poles or anchor structures require the conductor to be brought to its final, tight tension. This often involves applying substantial pulling force. The "terminal tackle block" is specifically designed to handle these immense loads, functioning as a key component in a pulley system (tackle system) that multiplies the pulling force from tensioning machines or winches. Unlike lighter Stringing Blocks, these blocks are built for sustained, high-tension applications, ensuring that the conductor can be safely and accurately tightened without slippage or damage. Their robust construction guarantees the integrity of the entire rigging system, crucial for the long-term performance and safety of the power line.

Product Features & Benefits:

• Exceptional High Load Capacity: Engineered for heavy-duty applications, capable of withstanding the immense tensile forces required for tightening conductors at terminal points, providing superior strength and safety margin.

• Optimized for Tensioning/Sagging: Designed specifically to integrate into tackle systems for applying and holding high tension on conductors during the critical sagging process, ensuring precise and controlled adjustment.

• Robust & Durable Construction: Manufactured from high-strength forged steel, heavy-duty alloys, and robust components, built to withstand continuous, high-stress use and extreme environmental conditions, guaranteeing extended service life.

• Precision Sheave & Bearings: Features a large-diameter, precision-machined sheave with high-quality, sealed bearings that minimize friction, allowing for smooth, controlled movement under heavy loads and preventing conductor damage.

• Superior Conductor Protection: The carefully designed groove, often lined with durable, non-abrasive materials like UMC (polyurethane), provides a secure and gentle contact surface, safeguarding the conductor from kinking, abrasion, or other costly damage during high-tension operations.

• Secure Attachment & Stability: Equipped with heavy-duty shackle or clevis connections for direct and secure attachment to strong anchor points on terminal structures, ensuring rigidity and safety under maximum tension.

• Corrosion Resistance: All components are typically hot-dip galvanized or treated with durable coatings, providing excellent protection against rust and environmental degradation, crucial for long-term field use.

Product Applications:

Our Heavy-Duty Terminal Tackle Block is indispensable for a variety of critical overhead transmission line projects, particularly during the final tensioning and sagging phases at anchor points:

• Terminal Pole Tensioning: Essential for bringing conductors to their final tension and sag at the end structures of a line section.

• Anchor Point Rigging: Used as a key component in tackle systems at anchor points where high pulling forces are exerted by Tensioners or winches.

• Long Span Sagging: Critical for accurately setting the sag of conductors on extremely long spans, where significant tension is required.

• Bundle Conductor Tensioning: Applied for precise and high-force tensioning of large conductor bundles, ensuring even load distribution among sub-conductors.

• Heavy Conductor Installation: Ideal for the installation of large, heavy conductors used in extra-high voltage (EHV) and ultra-high voltage (UHV) transmission lines.

• Re-tensioning & Line Upgrades: Used for re-tensioning existing lines or during upgrades where precise sag adjustment is necessary under high load.

• Any Application Requiring High-Force Tensioning: A core piece of equipment for any power line project that demands maximum pulling power for conductor installation.

Technical Data Sheet:

Note: Specific technical specifications, including exact sheave diameter, load capacity, and compatible conductor diameter, will vary depending on the model and intended application. Always verify the Working Load Limit (WLL) marked on the product. Please contact us for detailed datasheets and certified load test reports for specific product variants.
