Product Description
Our factory produces fiber optic with power cable in various structural types: including transmission ground wires with communication functions, as well as special cables that can be directly mounted on power poles. We can also produce OPPC (Optical Fiber Composite Overhead Phase Wire), MASS (Metal Self-Supporting Optical Cable), and GD (Hybrid Optical and Fiber Cable) models, each adapted to different power scenarios and meeting various mechanical strength and communication requirements.

Product Technical Parameters
Our factory's fiber optic with power cable incorporates the following three key technologies in design, construction, and operation and maintenance:
1.Fiber Optic Composite Structure Design Technology:
Depending on different requirements, our factory utilizes various methods to encapsulate the fiber optic units. The outer layer material balances current capacity and temperature control, and also provides corrosion protection. Depending on the application scenario, aluminum-clad steel wire, aramid yarn, and FRP are commonly used as the outer layer material.
2. Mechanical and Environmental Adaptability Technology:
Since power optical cables are often exposed to complex natural environments, they require excellent mechanical properties and environmental tolerance. Leveraging years of R&D experience, our factory precisely controls the impact parameters of temperature and distance on the cable, enabling us to produce more adaptable power optical cables for specific scenarios.
3. Electrical Safety and Insulation Technology:
Because optical cables often coexist with high-voltage lines, electrical safety is paramount. Our power optical cables are manufactured in strict accordance with international safety standards. The pressure resistance of our standard products exceeds the safety range of most common standards, ensuring safe use.
FAQ
Q: How to inspect the quality of fiber optic cables with power?
A: Quality inspection of fiber optic cables with power requires a comprehensive assessment of four aspects: structural integrity, optical performance, mechanical strength, and environmental adaptability.
First, check if the outer sheath of the cable is smooth and undamaged, with clear markings; whether the steel tape armor is double-sided rust-proof; and whether the loose tube is made of PBT material, avoiding the use of recycled materials or inferior PVC.
Second, test the fiber attenuation coefficient using an OTDR. At wavelengths of 1310nm and 1550nm, it should be below 0.35dB/km and 0.22dB/km, respectively; the lower the value, the better the performance.
Furthermore, conduct tensile, compressive, and bending tests to verify its stability under extreme stress. ADSS cables, in particular, must meet a rated breaking strength ≥90% RTS.
Finally, combine environmental tests such as high and low temperature cycling, tracking resistance, and UV aging to ensure long-term operational reliability. Reputable manufacturers should provide complete test reports that comply with standards such as GB/T 13993 and DL/T 832.
