Cable aluminium foil gives long-term protection to cable and prevents it from moisture and other naturally occurring elements. Aluminium foil mainly supplies 1000 series and 8000 series cable wrap foil, and the typical alloy is 1100, 8011, etc.
Except for 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.
Aluminium foil shielding is ideal for reflecting electromagnetic interference (EMI) and is often used in combination with a braided wire to absorb EMI.
YK Aluminum cable aluminium foil has good reflective (up to 98% of light and infrared heat) and barrier properties make it the material in electrical cables, providing long-term protection. It also insulates against magnetic and radiofrequency emissions. Cable wrapping aluminum foil provides perfect protection against magnetic fields and radio frequencies.
