OPGW Optical Ground Wire 60 Core Outdoor Aerial Fiber Optic Cable
The opgw cable central Al-covered steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. Al-covered Stainless Steel tube design increases the cross section of AL, to reach a better fault current and lightning resistance performance. Apply to the transmission line which requires small diameter and large fault current.
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.
