Application: Optical Ground Wire Layer Stranded combines excellent mechanical and electrical properties with much higher zero fiber strain margin to enhance long-term optical reliability. It is also more flexible and crush-resistant than other design types which makes pulling it in faster and makes it possible to pull farther and through more angles. Constructions: The conductor is consist of aluminum-clad steel wires / 6201-T81 aluminum alloy wires concentrically stranded. The stainless steel tubes with fibers will be laid in the layers according to specific requirement on fiber count, strength and electrical properties. 1. Central strength member (aluminum-clad steel or aluminum alloy wire) 2. Optical fiber 3. Stainless steel tube filled with water-blocking gel 4. Stranded wires (aluminum-clad steel wires and/or aluminum alloy wires) Features * Up to 432 fibers * Layer stranded construction provides more flexibility and options on design. * ACS wires are highly corrosion-resistant * Optical ground wire (OPGW) shields high voltage conductors from lightning strikes * Aluminum alloy wires provide conductivity for fault current Standards: ITU-TG.652 Characteristics of a single mode optical fiber.
