200m OPGW 36 Core Optical Ground Wire On Power Transmission Lines G652d Fiber
Optical Fiber Composite Ground Wire 36 Core Single Mode Uni-Tube Overhead Aerial Opgw Cable
Description:
OPGW is a kind of overhead ground wire containing optical fiber, which has multiple functions such as overhead ground wire and optical communication. It is applicable to new aerial power route to satisfy the needs for big conductors and high voltage transmission, and is used to conduct large fault short circuit current to provide anti lightning protection.
Application:
Optical fiber composite ground wire [OPGW] is suitable for installation on new power lines with double function of ground wire and communication. Especially for installation on normal voitage and extra high voltage power lines. OPGW can replace conventional ground wire of old power line with increasing fiber communication function. They conduct short circuit current and provide lightning resistance.
Product Characteristics:
• Large diameter, large fiber capacity
• The structure is stable and the reliability is high
• Excellent capability against side and outstanding short circuit current capacity
• The optimum stranding design can obtain the surplus length of secondary optical fiber • The number of strands can be designed in two or three layers
• Match with common ground wires
