Shielded Vs Unshielded Cable Introduction

Shielded cables

Shielded cables are used in various applications, including audio and video equipment and scientific instruments. Audio/video equipment is subject to electromagnetic interference (EMI) and radio frequency interference (RFI), requiring shielded cables to protect against EMI. Likewise, network transmission lines and computer cables are commonly shielded to protect against EMI, which can affect the quality of data signals. For example, suppose EMI from other devices on a network line interferes with the signals transmitted. In that case, this could cause errors in the data exchange between two computers on that network and other problems. Another common application for shielded cables is scientific instrumentation, where shielding is often required by international standards for products used in many laboratory settings.

Unshielded cable

Unshielded cable is a type of electrical wire that does not have a metallic shield surrounding it. unshielded cable has been used in low-voltage applications, such as homes and offices. However, some disadvantages of an unshielded cable may make it less desirable in high-voltage or critical applications. For example, these cables can be more susceptible to interference from other electrical devices than shielded cables, which could cause signal degradation. They can also be more vulnerable to damage from outside sources.
