In electrical cables, aluminium foil is an essential component providing long-term protection. It also insulates against magnetic and radio frequency emissions. Used in fibre-optic cables, aluminium foil acts as a ‘tracer’ to enable testing of the integrity of cable links.
Aluminium foil is a key material for cable protection as it provides a perfect barrier and is highly resistant to corrosion and heat. As a sheath for cables, aluminium foil helps to
