Multicore Shielded Cables

There are two types of shielding typically used for cables namely, foil and braid. Foil shielding uses a thin layer of aluminum, typically attached to a carrier such as polyester to add strength and ruggedness, which is good. A drain wire is used to terminate and ground the shield.Braid is a woven mesh of bare or tinned copper wires. The braid provides a low resistance path to ground and is much easier to termination by crimping or soldering when attaching a connector. The braid is more effective as a shield.
