OPGW Optical Ground Wire 72 Core Outdoor Aerial Fiber Optic Cable
OPGW cable is a type of cable structure with composite of optical transmission and overhead ground wire for power transmission. Its working in power transmission line both as optical fiber cable and overhead ground wire which can provide protection of lightning strike and conducting short circuit currency.The OPGW consist of stainless steel tube optical unit, aluminum cladding steel wire, aluminum alloy wire. It has central stainless steel tube structure and layer stranding structure. We can design the structure according to different environment condition and customers requirements.
Features
1.Large diameter, large fiber capacity
2.The structure is stable and the reliability is high
3.Excellent capability against side and outstanding short circuit current capacity
4.The optimum stranding design can obtain the surplus length of secondary optical fiber
5.The number of strands can be designed in two or three layers
6.Match with common ground wires

Packing and Shipping
Cable is supplied in lengths as specified in PI or as requirement. Each length will be shipped on a separate iron-wooden drum. The minimum barrel diameter of the drum will not be less than 30 times the cable diameter.
The cable ends will be sealed with plastic protection caps to prevent water penetration. The ends will be easily accessible for testing. A final inspection test report with attenuation performance data for each fiber is attached inside the drum.
