1040 Series Large Diameter Stringing Block | ACSR LGJ1120 Conductor Pulley for 1000kV Overhead Transmission Line

Product Name

1040 Series Large Diameter Stringing Block

Product Description

The 1040 series large diameter stringing block is a professional tool for conductor stringing of overhead transmission lines. Sheave dimension: Outer diameter Φ1040 mm, Inner diameter Φ900 mm, Width 125 mm, maximum applicable conductor LGJ1120 ACSR, suitable for power line construction under 1000kV.
We supply single, triple and five-sheave models. Sheave materials include aluminum alloy, MC nylon, rubber-coated aluminum and MC nylon with optional neoprene lining. Standard version adopts full rubber coating on conductor sheaves; please specify half rubber coating in the contract if required.
The pulley groove allows the passage of rotating connectors, bending-resistant connectors and compression sleeve protectors up to J1120B. It is designed for stringing aluminum conductors and ACSR on tangent towers, connectors and compression sleeves can pass smoothly through the sheave groove. All products are tested strictly according to DL/T 371-2010 and DL/T 685-1999 standards.

Application Scenarios

• Overhead high voltage transmission line construction below 1000kV
• Stringing LGJ1120 ACSR large-section conductors
• Single / double bundle / quad bundle conductor stringing on tangent towers
• Power grid upgrading & UHV transmission line auxiliary construction

Selection Tips
Select sheave quantity by conductor bundle: single conductor → single sheave; double bundle → triple sheave; quad bundle → five sheave.
Rated working load shall be calculated by the maximum vertical load acting on the pulley from conductor tension. For multi-sheave blocks, total load is the sum of each sheave load. Estimate load based on conductor weight within vertical span.
