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.
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
