Solid Inner Conductor and Six-Layer Construction

The CFP520 coaxial cable features a solid silver-plated copper inner conductor (1.29 mm) for superior current capacity and minimal resistive loss. Surrounding layers include LD-PTFE dielectric, silver-plated copper ribbon, high-temperature aluminum foil, silver-plated copper braid, and an outer FEP jacket—forming a robust six-layer structure optimized for both electrical and mechanical stability. This configuration delivers consistent impedance control and low attenuation of 0.28 dB/m @ 1 GHz and 1.26 dB/m @ 18 GHz, ensuring excellent RF power efficiency.

Outstanding Shielding and Thermal Endurance

With > 100 dB EMI suppression, the CFP520 cable ensures ultra-clean signal transmission even in high-energy environments. Its 5.20 mm FEP jacket withstands temperatures from –55 °C to +200 °C while providing strong resistance to chemicals and abrasion. The 26 mm single-bend and 52 mm repeated-bend radii allow durable installation and long service life.
