How does the integrated non-armored cable (GYXY) achieve high reliability with a lightweight structure?

In the selection and deployment of communication optical cables, weight, protection and environmental adaptability are key considerations. Although traditional armored cables have high mechanical strength, the presence of their metal armor layer also brings problems such as increased weight, limited construction flexibility and lightning strike risks. The integrated non-armored cable (GYXY) achieves lightweight while maintaining a high protection level through optimized structural design, providing a more efficient solution for overhead laying.

The core advantage of unitube non-armored cable(GYXY) lies in its compact and efficient layer-twisted structure. Compared with armored cables that rely on metal armor layers to provide compression and tensile properties, GYXY uses high-strength central reinforcements and peripheral loose tubes to work together to ensure sufficient mechanical support and avoid additional weight burden. This design reduces its overall weight by 20%-30% compared to similar armored products, thereby greatly reducing the load-bearing requirements on poles and towers. In the overhead laying scenario, this feature not only reduces the infrastructure cost, but also significantly improves the construction efficiency - the lighter cable body is easy to pull and fix, reducing the investment of manpower and machinery, especially suitable for long-distance and large-span deployment environments.

The optimization of the flexible structure further enhances the applicability of unitube non-armored cable(GYXY). Due to the rigidity limitation of the metal layer, traditional armored cables usually require a larger bending radius, which may face installation difficulties in complex terrain or dense urban wiring. The non-armored design of GYXY gives it better flexibility and allows a smaller bending radius, thus showing higher adaptability in scenarios such as corners and overhead pipes. This feature makes it more advantageous in wiring operations in mountainous areas, hilly areas or densely built areas, reducing the difficulty of construction and the potential risk of optical fiber damage.

In terms of protection performance, GYXY's all-dielectric structure completely avoids the inherent defects of armored cables. Although the metal armor layer can provide additional mechanical protection, it may become a conductive path for induced lightning strikes in thunderstorm-prone areas, causing equipment damage or even communication interruption. GYXY uses non-metallic materials to build a complete protection system, completely eliminating such risks, making it particularly suitable for areas with frequent lightning activities. It is worth noting that its lightweight design does not sacrifice protection capabilities - through the combination of high-density polyethylene (HDPE) sheath and double-sided plastic-coated steel belt longitudinal wrapping process, GYXY has excellent performance in waterproofing, pressure resistance and UV resistance, and the waterproof level can reach IP67, ensuring stable operation in long-term outdoor environments.

Long-term reliability is an important indicator for measuring the performance of optical cables, and the structural design of unitube non-armored cable(GYXY) fully considers environmental tolerance. The fiber paste filling in the loose tube and the water-blocking steel belt form a double moisture-proof barrier, which effectively inhibits water vapor penetration and delays optical fiber aging; the anti-UV additives of the outer sheath ensure weather resistance under strong sunlight conditions, avoiding sheath cracking or performance degradation due to material degradation. In addition, its symmetrical structural design makes the stress distribution of the cable more uniform when the temperature changes, reducing the possibility of micro-bending loss, thereby maintaining stable optical performance in long-term use.

As communication networks develop towards high density and lightweight, the non-armored technology path represented by GYXY shows broad application prospects. Its design logic not only conforms to the green and low-carbon industry trend, but also provides new ideas for the selection of optical cables in special environments. In the future, with further breakthroughs in material science and manufacturing processes, non-armored cables are expected to play a greater role in more demanding application scenarios, and promote the evolution of communication infrastructure towards a more efficient and reliable direction.
