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.
Aluminum foil shielding is ideal for reflecting electromagnetic interference (EMI) and is often used in combination with a braided wire to absorb EMI.
Bare copper braid shielding provides superior physical protection, while maintaining good flexibility and flex life. These shields are ideal for minimizing interference at all frequencies and have a lower dc resistance than foil.
Bare 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. Spiral shields are most effective in the use of cable where audio signals are transmitted.
A dual layer of tinned copper braid shielding provides superior physical protection and high coverage, while maintaining good flexibility and flex life. These shields are best for minimizing interference at all frequencies and have lower dc resistance than foil. The tin plating also adds 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.

The drain wire is a part of a shield within a cable that reduces the resistance from any point on the shield to ground. A drain wire carries extraneous electrical noise to ground and away from the circuit or system. The tin plating also adds 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.
Magnesium Aluminium braid shielding is a cost effective shielding solution, not only is electrical interference minimized, physical protection and flexibility are greatly increased compared to foil. The application-wise developed Magnesium Aluminum alloy offers a dependable and affordable shielding solution, therefore a reliable installation can be expected at all times.
