The role of the shielded wire is mainly to avoid interference signals entering the inner conductor, while reducing the loss of the transmitted signal. The shielding line can isolate the electromagnetic field noise source from the sensitive device and cut off the propagation path of the noise source. Specifically, the shielding wire can effectively prevent the influence of external electromagnetic interference (EMI) and radio frequency interference (RFI) on the internal transmission signal through the reflection, absorption and guidance of its metal shielding layer.

Structurally, the shielded wire is usually composed of an internal wire, an insulation layer, a metal shield layer and an outer sheath. Among them, the metal shielding layer is the core part of the shielding line, which can effectively block the entry of external interference signals, while reducing the leakage of internal signals.

In practical applications, shielding lines are widely used in a variety of occasions that need to prevent interference, such as communications, audio, broadcast, sound systems, anti-theft alarm systems, intelligent automation systems and fire protection systems. By using the shielded wire, the stable transmission of the signal can be ensured and the reliability and performance of the system can be improved.

In terms of shielding effect, RVVP shielded cable adopts multi-shielding layer mode, which ensures the accuracy and stability of signal transmission more effectively. The shielding layer is usually made of copper wire mesh, and sometimes metal thin preparation may be used, the main purpose is to ground the shielding layer, so as to isolate the external interference signal. When interference signals are introduced into the ground, it prevents these signals from entering the inner conductors, thereby reducing the loss of the transmitted signal.

At the same time, the interior of the RVVP cable is composed of multiple fine wire conductors, which not only helps to reduce the resistivity, but also improves the transmission efficiency. The anti-interference layer wrapped in its outer layer can also effectively avoid signal fluctuations and further improve the shielding effect.

In summary, RVVP shielded cable has good shielding effect in design and structure, and is suitable for a variety of application scenarios requiring anti-interference line connection.
