2KN Double Sheave Block: OPGW & Overhead Grounding Wire Exchanging Roller
The SH2-OPGW series Double Sheave Block is a specialized precision tool designed for exchanging overhead grounding wires with OPGW (Optical Budget Ground Wire) in live-line or de-energized operations. Engineered by Suntech Power, this lightweight block features a dual-sheave configuration that ensures balanced traction and minimizes the risk of fiber optic damage during stringing. Weighing as little as 2.2kg, it is optimized for high-altitude efficiency and long-distance line replacement projects.
Our line exchanging blocks are built to ISO 9001:2008 standards, ensuring reliability in critical power utility environments:
| Item Number | Model | Outing Size (mm) | Rated Load (KN) | Weight (kg) |
|---|---|---|---|---|
| 20123 | SH2-OPGW1 | 152 x 110 x 343 | 2 KN | 2.4 kg |
| 20124 | SH2-OPGW2 | 128 x 65 x 365 | 2 KN | 2.2 kg |
- Rated Load: 2 KN (Safe working load for fiber optic cables)
- Sheave Material: High-quality MC Nylon (To prevent abrasion on OPGW)
- Warranty: 1 Year
- Dual-Sheave Balance: The double-wheel design provides stable support for the "old-wire-pulls-new-wire" method, preventing twisting during the OPGW exchange.
- Ultra-Lightweight Design: At only 2.2kg, it significantly reduces the labor intensity for linemen working on overhead lattice towers.
- Fiber-Safe Sheaves: Typically equipped with nylon sheaves that provide a smooth, low-friction path, protecting the delicate internal optical fibers from mechanical stress.
- Compact Form Factor: The streamlined outing size allows for easy transport and rapid deployment in restricted tower spaces.
- OPGW Stringing & Exchanging: Primary use in replacing aging overhead ground wires with modern OPGW.
- Live-Line Maintenance: Suitable for power utility upgrades where minimizing downtime is critical.
- Transmission Line Upgrades: Essential for telecommunication and power grid integration projects.
No. This block has a rated load of 2KN and is specifically designed for lightweight OPGW or grounding wires. For heavy conductors, please refer to our heavy-duty single sheave stringing blocks.
The nylon sheave is non-conductive and softer than steel, which ensures that the OPGW's aluminum-clad steel wires and internal fibers are not crushed or scratched during the exchange process.
We have a steady supply ability of 1000 PCS per month to support large-scale national grid projects.
