As a leading OPGW manufacturer with 21 years of expertise, GL FIBER® delivers high-performance OPGW cable solutions tailored to your exact project requirements. Our OEM & custom OPGW services are built on four critical design elements:
1️⃣ Custom Diameter – Optimized for Installation & Performance
We engineer OPGW cables in precise diameters (8mm~20mm) to match:
- Tower loading capacity
- Wind & ice load conditions
- Compatibility with existing hardware
2️⃣ Cross-Section Design – Balanced Electrical & Mechanical Properties
Our proprietary multi-layer stranding technology combines:
- Aluminum-clad steel (ACS) wires – Superior conductivity & corrosion resistance
- Stainless steel tubes – Crush-resistant fiber protection
- Custom alloy ratios – Tailored to fault current requirements
3️⃣ Short-Circuit Current Capacity – Grid Safety Assurance
Every design undergoes IEC 60794-4-1 thermal stability tests for:
- 20kA~63kA fault current withstand
- <200°C conductor temperature during faults
- Zero fiber attenuation spikes post-fault
4️⃣ Rated Tensile Strength (RTS) – Engineered for Long Spans
We validate RTS (24kN~120kN range) through:
- Full-scale tensile testing (per IEEE 1138)
- Stranding angle optimization for stress distribution
- Dynamic sag-tension modeling
