Shielding Performance

The 100% shielding coverage on the power cable provides comprehensive protection against electromagnetic interference. The shield surrounds all three conductors and is drained at the wall side to prevent ground loops while maintaining effective EMI rejection.

The shielding effectiveness exceeds 80dB for most interference frequencies, with particular strength in the audio frequency range and switching power supply harmonics. This level of protection ensures that external electromagnetic fields from routers, wireless devices, and other digital equipment do not couple into your power lines and affect audio quality.

Connector Performance Features

Furutech connectors incorporate several advanced design features that enhance electrical performance and long-term reliability. The α (Alpha) pure copper conductors provide excellent electrical conductivity, while the 24k gold plating ensures corrosion resistance and stable contact resistance over time.

The Floating Field Damper System prevents induced magnetic fields that could create electromagnetic interference. The Earth (Ground) Jumper System ensures proper grounding continuity, while the metal cable clamps provide secure mechanical connection and resonance control.

Temperature and Environmental Ratings

The power cable operates reliably across a wide temperature range from -20°C to +75°C, making it suitable for various installation environments. The PVC jacket provides moisture resistance and UV protection, while the OFHC copper conductors maintain stable electrical characteristics across the operating temperature range.

The cable’s thermal stability ensures that resistance changes remain within ±0.1% across the full temperature range, providing consistent power delivery regardless of environmental conditions. This stability is particularly important for maintaining audio system performance as ambient temperatures vary.

Mechanical Specifications

The cable’s mechanical design balances flexibility with durability. The minimum bend radius of 10× cable diameter (140mm) prevents conductor damage during installation while maintaining the cable’s electrical characteristics. The stranded conductor construction provides flexibility for routing while maintaining current-carrying capacity.

The cable can withstand up to 10,000 flex cycles at the minimum bend radius, making it suitable for permanent installations where occasional movement may occur. The maximum pull tension of 25 lbf (111 N) ensures safe installation without conductor damage.

Installation and Safety Considerations

The power cable meets all applicable electrical codes and standards for 15-ampere circuits. The 14AWG copper conductors are rated for 15-ampere overcurrent protection per NEC requirements, ensuring safe operation in standard household electrical systems.

The single-point shield grounding at the wall side prevents ground loops while providing effective EMI protection. This grounding strategy is crucial for maintaining audio system performance and preventing interference coupling between equipment.

Quality Assurance and Testing

The  cable construction meets rigorous quality standards for professional audio applications. The OFHC copper conductors undergo purity testing to ensure 99.99% copper content, while the shielding effectiveness is verified through electromagnetic compatibility testing. The Furutech connectors are manufactured to precise tolerances and undergo quality control testing including contact resistance measurement, insulation testing, and mechanical durability verification. This comprehensive testing ensures consistent performance and long-term reliability.
