Six-pair shielded underground (60/0 CCAM)

1. Technical Section

Product Name: “Noan‑G06F” Underground Telephone Cable
Application: Underground telephone lines with six simultaneous pairs, suitable for underground routes, ducts, and indoor environments requiring protection against noise and environmental conditions

Internal Structure
• Conductor: CCAM (Copper‑Clad Aluminum) with 60/0 structure (60 fine strands)
• Effective conductor area: designed according to project requirements (e.g., ~0.13 mm² or ~0.17 mm²)
• Pair structure: six 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 underground applications
• Outer Jacket: UV-resistant PVC or a composite for outdoor installation

Electrical and Performance Specifications
• Conductor diameter: ~0.60 mm for six-pair cables (based on reference products)
• 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 as per manufacturer guidelines)

Installation and Maintenance Notes
• Install in ducts, underground, or protected paths
• Protect crossings from obstacles with clamps or protective sleeves
• Connect shield to ground at a single point for optimal performance
• Avoid sharp bends and respect bending radius
• Perform insulation resistance and line performance tests after installation

Noan‑G06F Six-Pair Shielded Underground Telephone Cable

Noanir Niroye Paytakht proudly presents the Noan‑G06F cable; a six-pair shielded underground telephone cable designed for indoor and underground environments requiring multiple simultaneous telephone lines. The lightweight CCAM conductor (60/0 strands), combined with proper insulation and aluminum shielding, ensures high performance against environmental interference. The Noan‑G06F is ideal for urban or intercity projects requiring multiple telephone lines along an underground route, providing environmental durability, stable signals, and reliable operation.

Key Features:
• Six twisted pairs
• Full foil shield around the core
• Lightweight CCAM conductor with 60/0 structure
• Durable design for indoor and underground installation
• High insulation resistance testing
• Optimal performance under environmental conditions

3. Description, Applications, and Comparative Analysis

Suitable Applications
• Medium-pair underground telephone lines
• Underground or in-structure routes in telecom projects
• Areas with moderate electromagnetic interference
• Urban or rural areas requiring multiple lines in one route

Advantages
• Multiple simultaneous telephone lines without separate cables
• Effective noise protection due to foil shielding
• Lower installation cost with one cable for multiple pairs
• Lighter and more cost-efficient than full copper cables

Disadvantages
• Higher conductor resistance compared to full copper
• Shield performance decreases if not properly grounded
• Precise installation and adherence to standards are critical
• Signal loss may be noticeable over longer distances

Comparison with Lower-Pair Models
• Compared to one- or two-pair cables, six-pair cables have denser cores, potentially increasing crosstalk; precise twist lengths and continuous foil are essential
• Production cost is slightly higher, but the benefit of multiple lines in a single cable is significant

Quality Assurance and Production Control
• Precise control of strand count (60) and conductor uniformity
• Guarantee of foil thickness, adhesion, and quality
• Insulation, thermal aging, mechanical, and vibration testing for samples
• Cable marking includes product name, manufacturer, technical specs, and production date
• Test reports for insulation resistance and company performance provided to customers
