20kN Multi-Purpose Crossarm Stringing Block for OHTL Conductors

20kN Multi-Purpose Crossarm-Mounted Stringing Block: Three-in-One Versatility for Overhead transmission lines

At Ningbo Changshi Electric Power Machinery Manufacturing Limited, we are continually innovating to provide highly efficient and adaptable solutions for the evolving demands of overhead transmission line (OHTL) construction. Our 20kN Multi-Purpose Crossarm-Mounted Stringing Block is a meticulously engineered, versatile tool designed to significantly enhance efficiency by serving three distinct purposes in a single unit. As a prominent China manufacturer and exporter, we offer a comprehensive one-stop supply for all your electrical construction and maintenance needs, and this innovative block exemplifies our commitment to adaptable design, robust performance, and unwavering reliability for diverse OHTL projects.

This advanced stringing block is a game-changer for field crews, eliminating the need to switch out different blocks for various stringing phases. It's expertly designed to handle:

1. conductor stringing: Providing smooth passage for power conductors.

2. Pilot Wire (Hauling Rope) Stringing: Guiding lighter pilot ropes efficiently.

3. Fiber Optic cable stringing: Safely handling delicate OPGW or ADSS fiber optic cables.

With its robust 20kN (approximately 4,500 lbs) rated capacity and secure crossarm mounting, this block ensures stable, controlled, and damage-free stringing, streamlining operations and reducing equipment inventory on site.

Product Features & Benefits:

• Three-Purpose Versatility: Uniquely designed to accommodate standard conductors, smaller pilot wires, and sensitive fiber optic cables (such as OPGW or ADSS) with optimal protection, reducing the need for multiple specialized blocks.

• High Load Capacity (20kN): Robustly constructed to safely manage tension loads up to 20 kilonewtons, making it suitable for a wide range of medium to heavy conductor stringing applications.

• Secure Crossarm Mounting: Features integrated clamping or bolting mechanisms for direct, stable, and secure attachment to utility pole crossarms, ensuring rigid positioning and precise conductor guidance.

• Interchangeable/Adaptable Grooves: May feature a universal groove profile, or easily adaptable liners/inserts that allow for quick transitions between different cable types while maintaining optimal protection.

• Smooth & Efficient Operation: Equipped with high-quality, sealed precision bearings that ensure exceptionally smooth and low-friction rotation, facilitating effortless pulling and minimizing stress on cables and equipment.

• Superior Cable Protection: The meticulously designed groove, often lined with durable, non-abrasive materials like UMC (polyurethane), safeguards conductors, pilot wires, and fiber optic cables from kinking, abrasion, or other costly damage.

• Durable & Robust Construction: Manufactured from high-strength galvanized steel or robust aluminum alloys, built to withstand the rigors of continuous field use and harsh environmental conditions, guaranteeing extended service life.

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

Product Applications:

Our 20kN Multi-Purpose Crossarm-Mounted Stringing Block is an invaluable asset for a broad spectrum of overhead power line construction and maintenance projects, offering streamlined efficiency:

• New OHTL Construction: Ideal for the entire stringing process, from pilot wire installation to main conductor and fiber optic cable (OPGW/ADSS) deployment.

• Complex Line Upgrades & Re-conductoring: Provides versatile support when replacing or upgrading existing lines that involve various cable types.

• Multi-Utility Corridor Projects: Efficiently handles different types of cables within a single corridor, simplifying logistics.

• Remote & Challenging Site Operations: Reduces the number of tools required, making logistics simpler for hard-to-access locations.

• Emergency Restoration: Provides a flexible and rapid deployment solution for various cable types during urgent repairs.

• Contractor Fleets: An essential tool for companies seeking to optimize equipment inventory and maximize crew productivity on diverse projects.
