2KN Rated Load OPGW Stringing Block with Ultra-Lightweight Design and Fiber-Safe Sheaves
Overhead Ground Wire Replacement Roller – 2KN Double Sheave OPGW Stringing Block
Product Overview
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. Featuring 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.

Product Advantages
· Dual-Sheave Balance — Double-wheel design provides stable support for the old-wire-pulls-new-wire method.
· Ultra-Lightweight Design — At only 2.2kg, significantly reduces labor intensity for linemen on towers.
· Fiber-Safe Sheaves — MC nylon sheaves provide smooth, low-friction path protecting delicate optical fibers.
· Compact Form Factor — Streamlined size allows easy transport and rapid deployment in restricted tower spaces.
Frequently Asked Questions (FAQ)
Q: Can this block be used for heavy conductor stringing?
A: No. Rated at 2KN, it is specifically designed for lightweight OPGW or grounding wires.
Q: What is the benefit of MC Nylon sheave?
A: Non-conductive and softer than steel, ensuring OPGW wires are not crushed during exchange.
Q: What is the supply ability?
A: Steady supply of 1000 PCS per month for large-scale grid projects.
Q: Is this suitable for live-line maintenance?
A: Yes, the nylon sheave provides electrical insulation for live-line operations.
