Product Description
Professional Tandem Sheave Stringing Block for Simultaneous Installation of Multiple Overhead Conductors
Product Overview
The Tandem Sheave Stringing Block is a specialized, high-capacity installation tool engineered for the efficient and safe installation of bundle conductors in high-voltage and extra-high-voltage transmission line projects. Unlike a standard single-sheave block, it features two or more independent sheaves mounted side-by-side within a single, robust frame. This design allows multiple sub-conductors—which together form a single-phase bundle—to be pulled simultaneously through the same support point on a transmission tower.
Product Specifications
| Item Number | Model | Applicable Conductor | Rated Load (kN) | Weight (kg) | Remark |
|---|---|---|---|---|---|
| 10211 | SHR-2.5 | LGJ300-500 | 25 | 11 | Aluminium sheave |
| 10212 | SHRN-2.5 | LGJ300-500 | 25 | 9.5 | Nylon sheave |
Key Features & Benefits
Enables Simultaneous Pulling of Multiple Bundle Conductors: Install multiple sub-conductors in a single, synchronized operation, dramatically reducing stringing time and labor costs.
Ensures Consistent Spacing and Alignment Within the Bundle: Sheaves fixed at precise engineered distances enforce correct spacing between sub-conductors for optimal electrical performance.
Dramatically Reduces Installation Time and Labor Requirements: Single setup of tensioning equipment installs entire phase bundle, minimizing crew exposure and accelerating project timelines.
Minimizes Wear on Stringing Equipment and Infrastructure: Consolidates work into one pull, reducing total cycles of wear on all associated equipment and lowering operating costs.
Improves Worksite Safety Through Fewer Equipment Operations: Reduces high-tension pulling events and operational phases, creating a safer work environment.
Provides Individual Bearing Protection for Each Conductor: Each sheave operates independently on its own sealed bearings, ensuring smooth travel and preventing conductor damage.
Designed for Heavy-Duty Use and Long-Term Reliability: Constructed from high-strength aluminum alloys or steel with reinforced frames and oversized axles for years of reliable service.
Facilitates Accurate Sag and Tension Control for the Entire Bundle: Promotes uniform sag across all conductors through simultaneous pulling under identical tension profiles.
Critical Tool for Modern High-Capacity Transmission Line Construction: Essential equipment for building or upgrading the high-voltage backbone of the power grid.
Offers Strong Return on Investment Through Operational Efficiency: Rapid ROI through reduced labor hours, shorter project durations, and improved scheduling reliability.
Summary
The Tandem Sheave Stringing Block is a force multiplier in transmission line construction. It transforms the labor-intensive process of installing bundle conductors from a series of sequential tasks into a single, coordinated operation. By enabling simultaneous pulling, it delivers unmatched gains in efficiency, ensures superior installation quality, enhances jobsite safety, and provides a compelling economic advantage. For any entity involved in building high-capacity power lines, this tool is not just beneficial—it is essential.
