Stranded Figure 8 Aerial Cable GYFTC8S

Name: Stranded Figure 8 Aerial Cable GYFTC8S
Availability: InStock

The GYFTC8S stranded figure-8 aerial cable integrates a fiber optic core with a steel wire messenger in a single self-supporting assembly, eliminating the need for separate lashing. The distinctive figure-8 cross-section places the messenger wire above the cable core, directly transferring tension loads while keeping the optical fibers strain-free. This design is ideal for pole-to-pole aerial deployments in access networks and rural fiber projects where rapid, cost-effective installation is essential.

The Figure 8 Fiber Optic Cable Aerial Stranded GYFTC8S is named “figure 8” due to its unique cross-sectional shape, resembling the number “8.” This design allows two fiber optic cable cores to be placed side by side within the same cable, forming a compact and efficient aerial installation solution. The fibers, 250μm , are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. FRP locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After an Steel tape (SPS) moisture barrier is applied around the cable core, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure.

Frequently Asked Questions

1. What is the advantage of figure-8 cable over lashed aerial cable?

Figure-8 cable integrates the messenger wire and fiber cable in a single assembly during manufacturing, eliminating the on-site lashing process. This reduces installation time by 40-60%, improves quality consistency (factory-controlled vs field-lashed), and simplifies pole attachment hardware requirements.

2. What distances can figure-8 cable span between poles?

Typical span distances range from 50 to 150 meters for standard installations. Longer spans up to 300 meters are possible with larger messenger wire diameters. The exact span depends on local wind/ice loading conditions and pole spacing.

3. Is figure-8 cable suitable for high-voltage power line corridors?

Figure-8 cable is typically used on telecom or low-voltage distribution poles, not on high-voltage transmission towers. For high-voltage environments (≥110kV), ADSS cable with AT sheath or OPGW is recommended due to electric field and grounding considerations.
