Optical Power Ground Wire (OPGW Cable)
Overview
OPGW integrates optical fibers within the ground wire of overhead high-voltage lines, combining lightning protection, grounding, and optical communication. It offers reliable data transmission, strong mechanical performance, and cost-effective installation by replacing traditional ground wires directly.
Key Features
-
High Protection: Stainless steel tube with water-blocking compound protects fibers from moisture and stress.
-
Strong & Durable: Excellent tensile strength for harsh environments.
-
Stable Electrical Performance: Reduces interference during short circuits.
-
Easy Installation: Fits standard ground wire specs; simple replacement.
-
Dual Function: Provides both grounding and high-speed communication.
-
Wide Use: Ideal for power lines, substations, and smart grids.
Structure & Specs
-
Stranded design with aluminum-clad steel or aluminum alloy wires
-
Fiber types: G652D, G655C, G657A1, OM3, OM4
-
Up to 96 cores
-
