Professional Industry Advantages

  • Ultimate Hand-Formable Stability with Enhanced Protection: The YZ670250/50 utilizes a .250-inch class tin-soaked architecture that combines the absolute shielding integrity of a rigid tube with the routing convenience of a flexible cable. The addition of a robust polymer jacket (FEP or LSZH) provides superior mechanical protection against abrasion and environmental stressors, ensuring a maintenance-free service life in exposed or high-traffic installations.
  • Exceptional Power and Voltage Integrity (3000V): Specifically engineered for mission-critical power environments. With its 1.65 mm large-gauge solid silver-plated copper conductor, this cable provides unrivaled current-carrying capacity and a significant safety margin for high-voltage pulse and high-wattage transmitter applications.
  • Superior Signal Fidelity (VSWR 1.10): Optimized for precision high-frequency performance, the cable maintains an exceptionally low Voltage Standing Wave Ratio (VSWR) of 1.10 or less at up to 6 Gigahertz. This eliminates signal reflections and ensures maximum energy transfer efficiency in sensitive microwave circuitry.
  • 100 Percent Absolute Shielding: By utilizing a fully integrated tin-soaked metal braid barrier, this cable prevents any signal leakage or ingress. This architecture is essential for maintaining signal purity in high-density electronic warfare (EW), aerospace radar systems, and precision measurement laboratories.
  • Unmatched Thermal and Phase Stability: The combination of high-purity Polytetrafluoroethylene (PTFE) insulation and the rigid-forming outer conductor ensures extremely stable electrical length and phase characteristics across a wide temperature spectrum from -55 degrees Celsius up to +125 degrees Celsius.
