Product Advantage
-
1
Exceptional Flexibility & Maneuverability: Boasts an ultra-small bending radius (15mm for single bend, 25mm for repeated bend) and a low bending moment of 0.7 Nm, enabling easy installation in tight spaces, complex routing scenarios, or equipment with limited clearance without compromising performance.
-
2
Superior Electrical Performance: Delivers stable impedance (50±1Ω) and excellent VSWR (≤1.15 at 30MHz-4200MHz), paired with high shielding attenuation (≥120dB) and low PIM (≤-158 dBc). Minimizes signal loss, interference, and distortion, ensuring reliable signal transmission even in high-frequency environments up to 19 GHz.
-
3
Robust Mechanical Durability: Features a helical corrugated copper tube outer conductor, 600N tensile strength, and 18 N/mm flat plate crush strength. Resists physical damage from pulling, crushing, or repeated bending during installation and long-term use, extending service life in harsh operating conditions.
-
4
Broad Environmental Adaptability: Available with PE or LSZH jacket options to suit diverse application needs. PE jacket supports extreme temperature ranges (-70℃ to +85℃ for storage, -55℃ to +85℃ for operation), while LSZH jacket offers fire-retardant properties, meeting safety and environmental requirements for both indoor and outdoor installations.
-
5
High Power Handling & Reliability: With a peak power rating of 7.5 KW and excellent insulation performance (insulation resistance >10000 MΩ.km, DC breakdown voltage 2000 V), the cable safely handles high-power signal transmission. Rigorous jacket spark testing (3000 Vrms) ensures structural integrity and reduces the risk of electrical failures.
-
6
Compliant & Customizable: Fully certified to global standards (UL, ETL, CE, CPR, RoHS, REACH) for broad market acceptance. Supports customization of jacket material, length (100m-1000m/500ft-1000ft), and marking, adapting to specific project requirements while maintaining consistent performance and quality.
