| High Light | Low Friction Overhead Line Stringing Block ，High Load-Bearing Capacity Conductor Stringing Pulley ，Anti-Derailment Safety Aerial Stringing Block | ||
Overhead line stringing blocks (also known as conductor stringing pulleys or aerial stringing blocks) are essential specialized tools widely used in the erection, tension stringing, and maintenance of overhead power transmission and distribution lines. Designed to guide and support conductors, optical cables, and pulling ropes during construction, these products effectively reduce frictional resistance and prevent conductor abrasion, bending deformation, and derailment.
They are suitable for overhead line projects ranging from 10kV to 500kV and accommodate various conductor types, including conventional Aluminum Conductor Steel-Reinforced (ACSR), aluminum alloy conductors, and overhead optical cables.
Featuring a modular and lightweight design, these blocks offer flexible configurations—such as single-wheel, three-wheel, and multi-wheel setups—to suit diverse construction methods, including single-conductor stringing, bundled conductor stringing, and helicopter-assisted aerial stringing. They serve as standard equipment for power grid construction and overhead line renovation projects.
Common standard specifications for overhead line stringing pulleys, covering light, medium, and heavy-duty models:
| Model | Number of Sheaves | Rated Load (kN) | Sheave Outer Size (mm) | Groove Inner Diameter (mm) | Applicable Conductor (ACSR mm²) | Sheave Material | Overall Weight (kg) |
|---|---|---|---|---|---|---|---|
| SHC-1A | 1 | 10 | Φ160*40 | 120 | 95~120 | Aluminum Alloy | 2.5 |
| SHD-200X60 | 1 | 15 | Φ200*60 | 160 | 150~240 | MC Nylon | 4.1 |
| DNH1-508*100 | 1 | 20 | Φ508*100 | 408 | ≤400 | MC Nylon | 17 |
| DNH1-660*100 | 1 | 20 | Φ660*100 | 560 | ≤500 | MC Nylon | 32 |
| SHS660 | 3 | 40 | Φ660*90 | 560 | ≤500 | Rubber-coated Aluminum | 106 |
| 7FXH-508MC | 7 | 75 | Φ508*75 | 408 | ≤400 | MC Nylon | 106 |
During overhead line stringing operations, these pulleys are secured to tower cross-arms or suspension points. Conductors or pulling ropes are placed within the pulley grooves, and tension is applied using pulling equipment. The low-resistance rotation of high-precision bearing pulleys converts sliding friction into rolling friction, significantly reducing pulling resistance while preventing conductor damage and ensuring compliance with power construction standards.
