Shielded Jacketed Cable Assemblies

Shielded Jacketed Cable Assemblies

‌ Shielded cable assemblies are widely used in reducing electromagnetic interference, improving signal quality, enhancing durability, ensuring personal safety, promoting environmental protection and energy saving, and play an important role in the development of electrical systems

Why Is Shielding Cable Needed?
Cable assemblies used for the transmission of data need to be protected from electromagnetic interference (EMI). EMI is a disturbance, sometimes called noise, which affects an assembly or electrical circuit due to either electromagnetic induction or electromagnetic radiation emitted from an external source.The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the circuit and can range from a simple degradation of data to a total loss of data.The source of the disturbance may be any object, artificial or natural, that carries rapidly changing electrical currents, such as nearby electrical circuits and machinery.Installations such as the factory floor, data centers, and offices are typically electrically noisy environments. Electrical noise either radiated or conducted as electromagnetic interference (EMI), can seriously disrupt the proper operation of neighboring equipment. An assembly's insulation and jacket material protect a cable mechanically from scrapes and abrasion and environmentally from moisture an

Types of Shielding cable：
1.Foil and braid cable assemblies.Foil shielding uses a thin layer of copper or aluminum, typically bonded to a carrier such as polyester to add strength and ruggedness.Tape shields provide 100% coverage of the conductors they surround, providing complete isolation from the external environment.Tape shields are thin which makes them difficult to work with, especially when applying a connector.Typically, rather than attempting to ground the entire shield, a drain wire is used to terminate and ground the shield.

2.Braided Shielded Cable Assemblies:The second method of shielding used for cables is braiding, which is a woven mesh of bare or tinned copper wires.The braid provides a low-resistance path to ground and is much easier to terminate by crimping or soldering when attaching a connector.Braided shields, however, do not provide 100% coverage.Depending on the tightness of the weave, braids typically provide between 70% and 95% coverage.Because copper has higher conductivity than aluminum and a braid has more bulk for conducting noise, a braid shield is more effective than tape shields.However, braid shields add size and cost to the cable.
