High-Power 50 Ohm Solid Silver-Plated Copper Coaxial Cable with 10.0mm FEP Jacket and High-Temperature PTFE Dielectric, Supporting 3kW Continuous Power at 100MHz for VHF/UHF Broadcast, Radar Systems, and Industrial RF Applications (-55°C to +200°C, ISO9001/CE Certified).
The Zhenjiang Worldpeak RG393 coaxial cable is a premium, high-power 50 ohm PTFE coaxial cable engineered for demanding RF transmission environments. Featuring a robust 10.0 mm outer diameter, this high-performance silver plated copper coax provides exceptional power handling and the lowest attenuation within the Zhenjiang Worldpeak flexible polymer product portfolio. Built with a solid silver-plated copper conductor and a high-temperature extruded PTFE dielectric, this RG393 coaxial cable ensures reliable signal integrity from -55°C to +200°C. It is the ultimate heavy-duty solution for commercial broadcast transmitters, military communications, aerospace systems, and high-frequency laboratory testing.
In modern RF engineering, high power coaxial cable systems must withstand extreme thermal stress while maintaining minimal signal degradation. The Zhenjiang Worldpeak RG393 coaxial cable is specifically designed to bridge the gap between rigid corrugated copper lines and standard flexible cables. By utilizing a massive 2.36 mm solid silver plated copper coax conductor core, this cable delivers an unmatched combination of structural flexibility and high-power handling capacity.
The engineering core of this RG393 coaxial cable lies in its high-temperature 50 ohm PTFE coaxial cable architecture. Unlike standard polyethylene-dielectric cables that degrade under moderate thermal load, the extruded solid polytetrafluoroethylene (PTFE) dielectric allows this cable to handle multi-kilowatt power levels continuously. This makes the Zhenjiang Worldpeak RG393 coaxial cable the preferred choice for industrial RF heating, plasma generation, and military radar installations where thermal runaway is a critical failure risk.
Superior Power Capacity: Engineered as a dedicated high power coaxial cable, it supports up to 3 kW of continuous RF power at 100 MHz under standard matched conditions.
Premium Silver Plated Copper Coax Construction: Both the solid inner conductor and the dense outer shield braid utilize high-purity silver plating to maximize electrical conductivity and minimize skin-effect losses.
High-Temperature Capability: The rugged combination of a solid PTFE dielectric and an extruded Fluorinated Ethylene Propylene (FEP) outer jacket enables dependable operation from -55°C up to +200°C.
Exceptional Shielding Integrity: The heavy-duty silver-plated copper braid delivers over 95% shielding coverage, protecting sensitive RF signals from electromagnetic interference (EMI).
Chemical and Environmental Resistance: The outer translucent FEP jacket provides outstanding resistance to petroleum, chemicals, ultraviolet (UV) radiation, and salt spray moisture.
Designing a high-performance 50 ohm PTFE coaxial cable requires strict manufacturing tolerances to prevent impedance variations. Zhenjiang Worldpeak resolves these challenges through advanced engineering practices:
Uniform Sintering Technology: Extruding a large-diameter 7.11 mm PTFE dielectric often introduces density variations that alter the local dielectric constant. Zhenjiang Worldpeak utilizes multi-zone sintering with slow, controlled cooling rates. This advanced process keeps density variations within ±0.5%, ensuring a highly consistent 50-ohm characteristic impedance along the entire cable length.
Skin-Effect Optimization: At VHF and UHF frequencies, electrical currents flow primarily along the outer surface of the conductor. The precision silver plating on the Zhenjiang Worldpeak RG393 coaxial cable conductor features an electrical conductivity of 62.1 MS/m, reducing overall RF attenuation by 3% to 5% compared to bare copper alternatives.
Robust Impedance Matching: Real-time concentricity monitoring during the extrusion phase guarantees that the distance between the silver plated copper coax conductor and the outer shield remains perfectly uniform, eliminating internal RF reflections.

Q: What is the maximum continuous power of this RG393 coaxial cable at 100 MHz?
A: In standard 40°C ambient conditions with a matched load (VSWR under 1.2:1), this high power coaxial cable handles up to 3 kW continuous. If your system runs at higher temperatures or higher VSWR, you must apply appropriate power de-rating factors.
Q: Why choose a silver plated copper coax over a standard bare copper version?
A: The high-purity silver plating significantly reduces signal attenuation at high frequencies by optimizing current flow through the skin-effect layer. It also prevents copper oxidation under prolonged exposure to high temperatures up to 200°C.
Q: Can Zhenjiang Worldpeak supply this 50 ohm PTFE coaxial cable with pre-installed connectors?
A: Yes. Zhenjiang Worldpeak specializes in custom RF cable assemblies. We can supply the RG393 coaxial cable pre-terminated, tested, and certified with N-Type, 7/16 DIN, or HN connectors to meet your exact project specifications.
