Thin Wall Alu Layered (ACT)

A Figure 8 Cable Solution for OPGW and OPPC

The ACT figure 8 cable performs in harsh climate conditions. An outer aluminum sheath protects the configuration from potentially threatening external influences, such as wind, ice, and rain. The aluminum layer is between 0.25 mm and 0.3 mm, making the cable simultaneously durable and lightweight, ideal for power lines. 

The stainless-steel tube protects the optical fibers from mechanical stress. The aluminum layer protects against hydrogen and prevents galvanic corrosion within the cable, which is a common cause of OPGW failure. We produce the fiber optic cable with up to 92 optical fibers at 250μm, and the durable ACT still weighs as little as 20 kg/km.
