Tinned copper spiral

Except the outer jacket that protects against physical damage a cable also has a shielding for protection against external signal interferences. These interferences may corrupt data transfer or create unwanted noise in an audio signal. Different types of shielding are used, as they differ in their specific advantage in protecting signal frequencies.

Tinned copper spiral is even more flexible than a braided shielding. This type of shield is constructed by wrapping the shield material in one direction around the conductors.The tin plating also aids to the copper in the cable as it not only helps to boost the copper’s properties, it also helps the wire to last much longer and counter acts against oxidation.
