Mini all-dielectric self-supporting optical cable |
Structural design |
Multiple loose casing structure |
Single loose casing structure |
Fiber capacity |
Up to 144 fibers |
Maximum 24 fibers |
Applicable span level |
50 to 200 spans |
80/100/120 spans |
Weight |
About 60-80 kg/km |
About 45-55 kg/km |
Tensile strength |
Long-term: ≥1500NShort-term: ≥3000N |
Long-term: ≥1000NShort-term: ≥2500N |
Diameter and flexibility |
Thicker, suitable for long-span overhead |
Thinner, more flexible, suitable for short-distance laying |
Typical application scenarios |
High-voltage transmission lines (long-span trunks)Urban backbone networksHigh-voltage transmission lines (short-span branches) |
Short-distance connections between substationsDistribution network communication links |
Environmental adaptability |
High tension, long span harsh environment |
Medium and low tension, short span ordinary environment |
Ⅱ. 4 Key Factors to Consider When Choosing ADSS or ASU Cables
1. Fiber quantity required
Choose ADSS cable: when the project requires more than 12 cores of fiber (such as 144-core Span above 200)
Choose ASU cable: if the fiber requirement is ≤24 cores (For example, 6-core ASU80 span cable)
2. Installation span requirements
ADSS cables support spans of more than 200 meters (such as between high-voltage transmission towers)
ASU cables are suitable for spans ≤ 120 meters (such as deployment on urban street light poles)
3. Environmental adaptability
ADSS cable uses double-layer sheath (HDPE+LSZH), UV resistance level UV4
ASU cable optimizes bending performance (dynamic bending radius is only 25D), suitable for areas with multiple bends
4. Cost-benefit analysis
