How to Choose ADSS Cable Span
ADSS cable span is a key specification for aerial fiber projects. A cable designed for the wrong span may experience excessive sag, tensile stress or long-term performance risk. Span selection should be confirmed before production.
What Does Span Mean?
Span is the distance between two supporting poles or structures. It affects the cable’s required strength, sag behavior and recommended construction.
Key Inputs for ADSS Selection
- Maximum and average pole-to-pole span
- Fiber count and cable diameter
- Wind speed, ice load and temperature range
- Installation tension and desired sag
- Route elevation changes and crossing conditions
- Proximity to power lines and electric-field requirements
Why Span Cannot Be Chosen by Fiber Count Alone
Two cables with the same fiber count can require different designs when installed across different spans or weather conditions. The cable’s aramid yarn content, strength member design and sheath construction must match the actual mechanical load.
Practical Selection Process
Provide a route profile, maximum span, pole type, installation condition, local weather and required fiber count. YITOFC can then recommend a suitable ADSS span range, cable diameter and drum length for the project.
Project Selection Checklist
Start with the route and application rather than a product name. Record whether the cable will be installed in duct, directly buried, aerial, wall-mounted or indoors; then confirm the fiber count, required capacity, expected service life and future expansion plan.
Information to Prepare Before Quotation
- Installation method and route condition
- Fiber count, fiber type and target application
- Mechanical conditions such as span, tension, crush risk, UV and moisture exposure
- Quantity, length per drum, delivery destination and packing requirement
- Required standards, labels, test reports and technical documentation
Common Specification Mistakes
Do not select a cable solely by its name, fiber count or lowest unit price. Similar-looking products may use different armor, water-blocking design, strength members, sheath material or test scope. Confirm the data sheet, construction drawing and inspection requirement before placing a volume order.
FAQ
Can the cable be customized for my project?
Yes. YITOFC can review fiber count, fiber type, cable structure, jacket, color, printing, meter marking, drum length and export packing according to the confirmed application.
Should I request samples or documentation first?
For a new model, tender or distribution program, request the technical data sheet and confirm the key construction details before production. Samples can be discussed according to the cable type and project requirement.
