Shielded wire, also known as shielded cable or screened cable, is a type of electrical cable used to transmit signals while minimizing electromagnetic interference (EMI) and radio frequency interference (RFI) from external sources. It consists of one or more conductors, which carry the electrical signals, surrounded by a metallic foil or a braided wire mesh shield.
The primary purpose of the shield is to protect the signals carried by the conductors from external electromagnetic fields. These fields can originate from nearby electrical devices, power cables, motors, or radiofrequency signals, and they have the potential to induce unwanted noise or interference in the signal-carrying conductors. By enclosing the conductors in a conductive shield, the majority of the external electromagnetic fields are redirected or absorbed, preventing their interference with the signals inside the cable.
Shielded cables are frequently used in applications where signal integrity is critical, such as audio and video transmission, computer networking, telecommunications, industrial automation, and medical equipment. However, shielded cables are often more expensive and bulkier than unshielded cables, so they are typically utilized when the benefits of reduced interference outweigh the additional cost and size considerations.

Mesh Sizes
The size of Shielded wire can be customized according to specific requirements. The common wire diameter ranges from 0.1 to 0.5 mm. The aperture sizes include 1×2 mm, 1×1 mm,, and other custom sizes are also available. The width ranges from 5 mm to 18 mm, and the coil length can be determined based on needs.
Properties Of Shielded Wire
1、Shielded wire is wrapped with a conductive shielding layer that effectively resists external electromagnetic interference. This design helps to maintain the integrity of signals inside the cable, reducing electromagnetic interference and radio frequency interference, thus enhancing the reliability of signal transmission.
2、Shielded wire efficiently prevents signal interference during transmission, preserving the original state of signals without distortion. This makes shielded wire well-suited for applications requiring high signal fidelity, such as audio, video, and data transmission.
3、Due to different types and structures of shielding layers, shielded wire can adapt to a wide range of interference frequencies, making it suitable for various application scenarios with excellent performance.
4、Shielded wire reduces electromagnetic radiation, minimizing its impact on the surrounding environment and other devices, thus enhancing the cable’s safety and reliability.
5、The external metallic foil or braided shield of shielded wire provides additional protection to the internal conductors, reducing the risk of signal interference or breakage due to external physical damage.
