Shielded cable

What are the types of Cable Shield?

There are many different types of cable shields. The purpose of shielding cable is to guard against external forces, such as Electrical or Electronic interference as well as physical protection. This protects the inside wires and ensures the integrity of the cable transmission. Below we will describe the most common shield types and the reason for having them. It is critical to understand that adding a shield to a cable changes the performance of the electrical and or electronic properties of said cable.

Cable Shield Definition

A metallic covering over a wire or a group of wires applied continuously throughout in order to protect it from physical, radio frequency interference (RFI), electromagnetic interference (EMI) and other types of external disruptions.

Cable Shield types

Shield type
DescriptionCable typeProtection type
Overall Foil Shield
An aluminum/Mylar tape helically applied over a cable with or without a drain wire.
Coaxial Cables, Mil-spec Wire, Triads
EMI, RFI
Overall Foil Shield & Drain WireAn aluminum/Mylar tape helically applied over a cable with a drain wire for terminating the shield.Multi-Conductors, Multi-Pairs, Triads
EMI, RFI
Individual Foil Shield & Drain Wire
An aluminum/mylar tape shield applied individually over a group of wires, usually pairs. Drain wires may be individually applied or only one common wire in contact will all of the shields.
