OPGW Cable Overview
Key Features & Advantages
-
Superior Protection: Stainless steel tube with water-blocking compounds shields fibers from moisture and stress.
-
High Strength: Compact, durable design resists tension and harsh environments.
-
Excellent Electrical Performance: Minimizes power grid interference during faults.
-
Easy Installation: Compatible with standard ground wire setups for direct replacement.
-
Dual Function: Provides grounding and optical communication simultaneously.
-
Wide Application: Ideal for power transmission lines, substations, and smart grids.
Main Functions
OPGW cables serve power communication systems, supporting relay protection, automatic control, and data transmission. Installed along high-voltage lines, they integrate optical communication and grounding in one system.
Structure
Made of two or three layers of aluminum-clad steel or aluminum alloy wires, OPGW is designed for the mechanical and structural demands of transmission lines.
Fiber Specifications
-
Fiber types: G652D, G655C, G657A1, 50/125, 62.5/125, OM3, OM4
-
Fiber count: up to 96 cores
Electrical & Application Range
-
For power lines ≤110KV and UHV systems
-
Suitable for new overhead transmission lines
-
Conducts short-circuit currents and provides lightning protection
Typical Design
Central aluminum-covered stainless steel tube ensures strong mechanical performance, excellent fiber protection, and long-term reliability.
