The Hasçelik HASC-OPGW-24F-ALT is a 24-fiber Optical Ground Wire (OPGW) utilizing a central aluminum tube design. This cable serves the dual function of a traditional shield/ground wire while simultaneously providing a high-capacity fiber optic communication path along the transmission line. Manufactured by Hasçelik Kablo — Turkey's largest cable manufacturer — to international IEEE 1138 and IEC 60794-4 standards.
The 24 single-mode optical fibers are housed in a sealed, water-resistant central aluminum tube filled with water-blocking gel, providing full mechanical and environmental protection. The optical unit is surrounded by one or more concentric layers of aluminum-clad steel (ACS) wires, delivering the mechanical strength and fault current capacity required for overhead transmission line service.
Key Performance Features:
- Fiber Count: 24 Single-Mode (ITU-T G.652D / G.657A1)
- Cable Construction: Central aluminum tube, ACS outer strands
- Operating Temperature: -40°C to +65°C
- Short-Circuit Fault Current Capacity: Per project specification (kA²·s)
- Corrosion-resistant, UV-stable outer layer
- Compliant with IEEE 1138, IEC 60794-4, IEC 61232
- Excellent lightning protection and low electrical resistance grounding path
