Product Description
Product Overview
OPGW (Optical Fiber Composite Overhead Ground Wire) combines grounding and communication functions in overhead power lines. Featuring a central stainless steel tube structure with layer stranding, this cable provides both electrical protection and high-speed data transmission capabilities.
Key Features & Advantages
- Replaces existing aerial ground wires while upgrading power system communication lines
- Synchronous planning and design with ground wire for new aerial power line construction
- Stainless steel tube fiber unit provides optimal protection
- Conducts large fault short-circuit current and provides lightning protection
- Suitable for high fiber count and super high voltage power lines (110KV+)
- Matches favorable tension-sag characteristics with different ground wires
Applications
OPGW is designed for installation on new power lines serving dual functions as ground wire and communication medium. Particularly suitable for normal voltage and extra high voltage power lines, it can replace conventional ground wires while adding fiber communication capabilities.
