How does 50 ohm RF corrugated copper tube coaxial cable improve the stability and efficiency of high-frequency signal transmission?

In modern communication systems, coaxial cable (Coaxial Cable) is an efficient signal transmission medium and is widely used in television broadcasting, wireless communication, data centers, military communications and other fields. Especially in radio frequency (RF) applications, the importance of coaxial cable is becoming more and more prominent. 50 ohm RF series corrugated copper tube coaxial cable has become an ideal choice for many communication devices due to its superior electrical performance, durability and high transmission efficiency.
Unlike traditional coaxial cables, the corrugated copper tube outer conductor increases the surface contact area through the corrugated structure, thereby reducing signal loss and improving signal transmission quality. In addition, the corrugated structure can also enhance the cable's anti-interference ability, enabling it to stably transmit high-frequency signals in complex electromagnetic environments.
Structural features of 50 ohm RF series corrugated copper tube coaxial cable
Inner conductor (center conductor)
Usually made of copper or copper-plated steel, it is responsible for transmitting electrical signals. The material and size of the inner conductor determine the transmission performance and signal quality of the cable. Copper inner conductors are widely used because of their good conductivity.
Dielectric material
The dielectric layer is usually made of materials such as polyethylene (PE) or foamed polyethylene (FEP), which plays the role of isolating the inner conductor from the outer conductor. The choice of dielectric material directly affects the characteristic impedance, signal transmission speed and signal attenuation of the cable.
Outer conductor (shielding layer)
The corrugated copper tube is used as the outer conductor. It adopts a corrugated structure and improves the anti-interference ability of the cable by increasing the surface contact area. The outer conductor effectively shields the external electromagnetic interference (EMI) to ensure the pure transmission of the signal.

Outer sheath
The outer sheath is generally made of polyvinyl chloride (PVC) or low smoke zero halogen (LSZH) materials with strong weather resistance and aging resistance, which can protect the internal structure of the cable from physical damage and ensure its long-term stable operation in harsh environments.
Advantages of 50 ohm RF series corrugated copper tube coaxial cable
Low signal attenuation
Since the corrugated copper tube outer conductor provides a better current conduction path, this cable can significantly reduce the attenuation of the signal during transmission, especially when transmitting high-frequency signals.
High anti-interference ability
The design of the corrugated structure makes the outer conductor have stronger anti-electromagnetic interference (EMI) ability, which can effectively block external noise and maintain the purity of the signal. This allows the 50-ohm RF series corrugated copper tube coaxial cable to work stably in a high-noise environment.
High transmission efficiency
50-ohm impedance is the most common standard in RF applications and is suitable for most communication equipment and systems. The cable can provide efficient signal transmission, ensure the stability of the system and the accuracy of the data.
Excellent durability
The corrugated copper tube outer conductor not only improves the electrical performance of the cable, but also enhances its mechanical strength, can resist physical damage such as bending and stretching, and extend the service life of the cable.
