The OPGW 24 Core G652D Fiber Optic Cable with a 100mm² cross-sectional area is a high-performance, dual-function overhead ground wire designed for modern electrical grids and substation communication networks. This robust cable features a stranded layer structure with a single central stainless steel loose tube, which safely houses 24 single-mode G.652.D fiber cores within a hydro-proof, jelly-filled protective chamber.

By surrounding the core laser-welded steel tube with a high-tensile armor of aluminum-clad steel (ACS) wires and aluminum alloy wires, this 100mm² configuration provides exceptional mechanical armor and electrical conductivity. It serves simultaneously as a conventional lightning protection grounding wire and a high-speed, low-attenuation telecom backbone for long-span high-voltage transmission lines.

• High-Voltage Transmission Grids: Installed as the critical overhead ground wire on 110kV, 220kV, and higher voltage power towers for lightning shielding and grounding.
• Substation Smart Communication Links: Enabling real-time grid monitoring, teleprotection, SCADA data routing, and automation broadband between power stations.
• Heavy-Load Meteorological Zones: Optimized for power line corridors crossing regions prone to intense winds, heavy ice loading, and high physical tension.
• Network Modernization Projects: Replacing aged, traditional overhead ground wires on existing transmission towers to add high-bandwidth optical channels without overloading the tower structures.

• Single Tube Stranded Efficiency: Concentrating the 24 cores into a single laser-welded stainless steel tube simplifies mid-span splicing, reduces the cable core diameter, and provides absolute hermetic moisture protection.
• Premium G.652.D Singlemode Cores: Industrial-grade fibers ensure ultra-low optical attenuation at both 1310nm and 1550nm wavelengths, perfect for long-haul grid communication.
• Robust 100mm² Cross-Section: Provides a heavy-duty thermal capacity that easily handles massive fault short-circuit currents while keeping a balanced strength-to-weight ratio for standard tower spans.
• Superior Environmental Defense: The high-quality aluminum cladding on the steel shielding wires delivers excellent corrosion resistance against atmospheric pollution, marine salt air, and acid rain.

With 13 years of specialized production experience, Shandong Yibo Optronics Technology Co., Ltd. manufactures utility-grade OPGW cables that comply fully with IEEE 1138 and IEC 60794 international standards.

• Advanced Laser Welding Line: Our high-precision continuous welding lines ensure uniform, flawless seams on the single stainless steel tube, eliminating the risks of hydrogen aging and water ingress.
• Rigid Quality Control: Every drum of 100mm² OPGW undergoes short-circuit current simulation, tensile load verification, and temperature cycling stress tests in our independent testing center prior to overseas shipment.
