Product Name: Aerial Telephone Cable “Noan‑A10F”
Application: Aerial telephone lines with ten simultaneous pairs, suitable for pole-to-pole routes requiring noise protection and environmental durability.

Internal Structure:

Conductor: CCAM (Copper‑Clad Aluminum) with 60/0 construction (60 very fine strands)
Conductor cross-section: Designed per project requirements (e.g., ~0.13 mm² or ~0.17 mm²)
Pair structure: Ten twisted pairs
Shield: Laminated aluminum foil wrapped longitudinally around the core (100% coverage)
Drain wire: Auxiliary conductor (copper or tinned copper) for grounding the shield
Insulation: PVC or PE suitable for terrestrial applications
Outer jacket: UV-resistant PVC or a blend suitable for outdoor installation

Electrical and Performance Specifications:

Conductor diameter: Based on reference “10-pair” cables, ~0.60 mm
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 reduces crosstalk and pair interference
Minimum bending radius: 10× overall cable diameter (or as per manufacturer guidelines)

Installation & Maintenance Notes:

Suitable for installation in conduits, underground, or protected routes
Protect points passing obstacles with clamps or protective sleeves
Ground the shield at a single point for optimal performance
Avoid sharp bends; follow minimum bending radius
Perform insulation resistance and line performance tests after installation

Product Name: Ten-Pair Aerial Foil-Shielded Telephone Cable Noan‑A10F

Description:
Noanir proudly introduces the Noan‑A10F; a ten-pair aerial telephone cable with full foil shield, designed for outdoor environments requiring simultaneous transmission of multiple telephone lines. The lightweight 60/0 CCAM conductor, combined with appropriate insulation and aluminum foil shielding, provides high performance against environmental interference. Noan‑A10F is ideal for urban or intercity projects needing multiple lines along aerial routes, offering environmental durability, stable signal, and reliable operation.

Key Features:

Ten twisted pairs
Full foil shield around the core
Lightweight 60/0 CCAM conductor
Durable design for indoor or underground installation
High insulation resistance testing
Reliable performance in outdoor conditions

Applications, Advantages & Comparative Analysis

Suitable Applications:

Terrestrial telephone lines with a high number of pairs
Underground or in-building telecommunications routes
Areas with high electromagnetic interference potential
Urban or rural areas requiring multiple lines on one route

Advantages:

Supports multiple simultaneous lines without separate cables
Effective noise protection via foil shield
Reduced installation cost using a single cable for multiple pairs
Lower weight and cost compared to full copper cables

Disadvantages:

Higher conductor resistance compared to full copper cables
Shield performance decreases if not properly grounded
Installation must adhere to standards and guidelines
Signal loss may occur over longer distances

Comparison with Fewer-Pair Models:

Compared to one- or two-pair cables, ten-pair cables have higher core density, increasing potential crosstalk; careful pair twisting and continuous foil design are essential
Production cost is relatively higher, but the benefit of multiple lines in a single cable is significant

Quality Assurance & Production Control:

Precise control of strand count (60) and conductor uniformity
Ensured foil thickness, adhesion, and quality
Insulation, thermal aging, mechanical, and vibration testing on samples
Product marking includes product name, Noanir company, technical specifications, and production date
Delivery of insulation resistance and performance test reports to customers
