Professional Industry Advantages
-
Heavy-Duty Hand-Formable Stability: The .250-inch diameter tin-soaked architecture provides a unique balance between rigidity and flexibility. It can be easily shaped by hand during installation to conform to complex chassis geometries. Once bent, it maintains its configuration permanently, offering the 100 percent shielding efficiency of a solid copper pipe without requiring precision tube-bending machinery.
-
Superior Power Handling & High-Voltage Rating: Designed for mission-critical power environments. With a 1.65 mm solid silver-plated copper conductor and a 3000V operating voltage rating, this cable provides an exceptional safety margin for high-wattage transmitters and high-voltage pulse applications.
-
Absolute Electromagnetic Isolation: By utilizing a fully integrated tin-soaked metal braid, this cable creates a perfect 100 percent shielding barrier. This prevents any signal leakage or ingress, which is critical for maintaining signal purity in high-density electronic warfare (EW) and aerospace radar modules.
-
Exceptional Signal Integrity (Ultra-Low VSWR): Optimized for precision high-frequency performance, the cable maintains an industry-leading Voltage Standing Wave Ratio (VSWR) of 1.10 or less. This ensures maximum energy transfer and prevents internal reflections that could compromise sensitive microwave hardware.
-
Thermal and Phase Stability: The combination of high-purity Polytetrafluoroethylene (PTFE) insulation and the rigid-forming outer conductor ensures consistent electrical length and phase characteristics across a wide temperature spectrum from -55 degrees Celsius up to +125 degrees Celsius.
