How to choose aramid to improve the performance of ADSS optical cable? Analysis of the key role of aramid quality

The following is an analysis of aramid selection, quality significance and AOTKE Cable's practical principles.

Ⅰ. Selection criteria for aramid in ADSS optical cable.

1. High strength and tensile resistance
Aramid needs to have an extremely high tensile modulus (usually ≥120 GPa) to withstand the deadweight and external loads (such as wind load, ice and snow) of ADSS optical cable when it is suspended.

2. Corrosion resistance and anti-tracking performance
Aramid insulation and chemical stability are key to resisting tracking corrosion caused by corona discharge in high-voltage environments.

3. Thermal stability
When exposed to a temperature difference of -40°C to 70°C for a long time, aramid needs to maintain stable performance to avoid thermal expansion that causes deformation of the optical cable structure.

Ⅱ. The significance of aramid quality to ADSS optical cable

Poor-quality aramid can cause the following problems in optical cables:
1. Mechanical failure: breakage after long-term stress, causing the optical cable to sag or break;

2. Shortened life: electrical trace corrosion accelerates sheath aging and increases maintenance costs;

3. Signal loss: structural deformation causes micro-bending of the optical fiber, affecting transmission performance.

Therefore, the quality of aramid directly determines the safety and service life of ADSS optical cables in complex environments.

Ⅲ. AOTKE Cable's aramid material selection principle

As a professional optical cable manufacturer, AOTKE Cable follows the following standards:
1. International certification: only use aramid suppliers that have passed ISO 9001 and UL certification;

2.Performance measurement: each batch of aramid must pass tensile strength, high temperature resistance and electrical tracking resistance tests;

3.Environmental adaptation: customize aramid parameters according to the climate of the deployment area (such as high humidity, strong ultraviolet rays);

4. Long-term reliability: verify the 20-year durability of aramid through accelerated aging experiments.

Ⅳ. How to distinguish the quality of aramid in ADSS optical cable?

·Visual inspection: high-quality aramid yarn has uniform color, no burrs or nodules;

·Tensile test: cut samples for tensile test, and the breaking strength must be ≥3000 MPa;

·Certification query: require suppliers to provide UL or IEC certification reports for aramid;

·Compare brands: optical cables using international brands of aramid such as DuPont are more reliable.

Summary

AOTKE Cable always selects aramid materials with strict standards to ensure that each ADSS optical cable has high strength, weather resistance and ultra-long life. If you need customized solutions or technical consultation, please contact our engineering team!
