Property Specification
Type: Sector-Wire Central SST Lightning-Shield OPGW
Standards: IEEE 1138, IEC 60794-4, IEC 60793, ITU-T G.652
Construction: Features a central stainless steel tube encapsulating the optical fibers, wrapped in double armor layers of aluminum-clad steel (ACS) wires. The inner armor layer consists of compressed (sector-shaped) ACS strands, while the outer armor layer utilizes either fully compressed sector wires or standard round ACS wires.
Applications: Specifically engineered for power transmission corridors located in severe lightning/thunderstorm-prone zones that require a compact cable footprint. By shaping standard round ACS strands into compressed sector profiles during stranding, the cable increases metallic cross-sectional area and outer wire thickness—drastically boosting fault-current carrying capacity and lightning strike endurance without enlarging the overall cable diameter.
