۱. Technical Section
Product Name: “Noan‑A15F” Aerial Telephone Cable
Application: Aerial telephone lines with fifteen simultaneous pairs, suitable for spans between poles requiring protection against noise and environmental conditions
Internal Structure
• Conductor: CCAM (Copper‑Clad Aluminum) with 60/0 (60 fine strands) structure
• Conductor cross-section: Designed according to project requirements (e.g., ~0.13 mm² or ~0.17 mm²)
• Pair structure: Fifteen twisted pairs
• Shield: Laminated aluminum foil longitudinally wrapped around the core (100% coverage)
• Drain Wire: Auxiliary conductor (copper or tinned copper) for grounding the shield
• Conductor Insulation: PVC or PE for terrestrial applications
• Outer Jacket: UV-resistant PVC or composite for outdoor installation
Electrical and Performance Specifications
• Conductor diameter: Based on reference 15-pair cables, ~0.60 mm per conductor
• Conductor resistance at 20 °C (max): ≤ 186 Ω/km for ~0.60 mm conductor
• Insulation resistance (min): ≥ 5000 MΩ·km
• Test Voltage: AC 1500 V (1 min) / DC 2250 V (1 min) without breakdown
• Operating Temperature: ‑20 °C to +60 °C
• Capacitance and Impedance: Twisted pair design minimizes crosstalk and pair-to-pair interference
• Minimum Bend Radius: 10 times overall cable diameter (or per manufacturer instructions)
Installation and Maintenance Notes
• Install in ducts, underground, or protected pathways
• Protect points where the cable passes obstacles with clamps or protective sleeves
• Connect shield to ground at a single point for optimal performance
• Observe bend radius and avoid sharp bends
• After installation, perform insulation resistance and line performance tests

Noan‑A15F Fifteen-Pair Aerial Foil-Shielded Telephone Cable
Description:
Noanir proudly presents the Noan‑A15F cable; a fifteen-pair aerial telephone cable with full foil shielding designed for outdoor environments requiring multiple simultaneous telephone lines. The lightweight CCAM conductor with 60/0 strands, combined with proper insulation and aluminum shielding, ensures high performance against environmental interference. The Noan‑A15F is ideal for urban or intercity projects needing multiple lines on aerial spans, offering environmental durability, stable signal, and reliable operation.
Key Features
• Fifteen twisted pairs
• Full foil shield around the bundle
• Lightweight CCAM conductor with 60/0 strands
• Robust design for indoor and underground installation
• High insulation resistance tested
• Optimal performance under environmental conditions
۳. Applications, Advantages, and Comparative Analysis
Suitable Applications
• Ground telephone lines with high pair counts
• Underground or in-structure pathways in telecom projects
• Areas with high electromagnetic interference potential
• Urban or rural areas requiring multiple lines in a single route
Advantages
• Multiple simultaneous lines without separate cables
• Effective protection against environmental noise via foil shielding
• Reduced installation cost using a single multi-pair cable
• Lower weight and cost compared to full-copper cables
Disadvantages
• Higher conductor resistance than full-copper cables
• Improper shield grounding reduces shielding effectiveness
• Precise installation and adherence to standards are critical
• Signal attenuation may be noticeable over long distances
Comparison with Fewer-Pair Models
• Compared to one- or two-pair cables, fifteen pairs increase core density, which may increase crosstalk; precise twisted pair length and continuous foil design are essential
• Manufacturing costs are higher, but the advantage of multiple lines in one cable is significant
Quality Assurance and Production Control
• Strict control of strand count (60 strands) and conductor uniformity
• Guarantee of foil thickness, adhesion, and quality
• Insulation, thermal aging, mechanical, and vibration tests on samples
• Cable printing includes product name, Noanir, technical specifications, and production date
• Test reports for insulation resistance and company performance are provided to customers
