1. Technical Section

Company: Noanir — Two-Pair Foil-Shielded Aerial Telecommunications Cable (60/0 CCAM) — Proposed Model: “Noan-A2F”

Product Name: Two-Pair Telecommunications Cable “Noan-A2F”
Application: Aerial telephone lines (over poles or between buildings) with protection against environmental noise

Internal Structure

Conductor: CCAM (Copper‑Clad Aluminum) with 60/0 structure (60 very fine strands)
Effective Conductor Area: Designed according to project requirements (e.g., ~0.13 mm² or ~0.17 mm²)
Twisted Pair Structure: Two 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
Insulation: PVC or PE suitable for terrestrial applications
Outer Jacket: UV-resistant PVC or a composite for outdoor installation

Electrical and Performance Specifications

Conductor Diameter: ~0.60 mm (typical for 2-pair reference cables)
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 inter-pair interference
Minimum Bending Radius: 10× 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 clips or protective sleeves
Connect shield to ground at a single point for optimal performance
Avoid sharp bends and maintain recommended bending radius
After installation, perform insulation resistance and line performance tests

Two-Pair Foil-Shielded Aerial Cable Noan-A2F

Noanir proudly presents the Noan-A2F two-pair foil-shielded aerial telephone cable, designed for aerial lines requiring environmental noise protection. Made with CCAM conductors (copper-clad aluminum) of 60 fine strands and two twisted pairs, the full foil shield minimizes electromagnetic interference. The Noan-A2F cable combines high durability, stable signal performance, and cost efficiency, making it an ideal choice for urban aerial telephone routes.

Key Features:

Two twisted pairs
Full foil shield around the pairs
Lightweight CCAM conductor with 60/0 strand structure
Rugged design suitable for indoor and underground installation
High insulation resistance
Reliable performance in various environmental conditions

3. Applications, Advantages, and Comparative Analysis

Suitable Applications:

Low-pair terrestrial telephone lines
Underground or in-structure telecommunications projects
Areas with moderate electromagnetic interference
Urban or rural locations needing multiple lines on a single path

Advantages:

Provides multiple telephone lines simultaneously without separate cables
Effective environmental noise protection via foil shield
Reduced installation cost by using a single cable for two pairs
Lower weight and cost compared to all-copper cables

Limitations:

Higher conductor resistance than pure copper cables
Shield performance decreases if grounding is improper
Precise installation and adherence to standards are important
Signal loss may be noticeable over long distances

Comparison with Other Pair Counts:

Compared to single- or four-pair cables, two-pair has lower core density, which may reduce inter-pair crosstalk; careful design of pair twist and continuous foil shielding is essential
Production cost is relatively lower, but the benefit of multiple lines in one cable is significant

Quality Assurance and Production Control:

Precise control of strand count (60 strands) and conductor uniformity
Assurance of foil thickness, adhesion, and quality
Insulation, thermal aging, mechanical, and vibration testing for samples
Product name, Noanir brand, technical specifications, and production date printed on the cable
Insulation resistance and performance test reports provided to the customer
