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 also helps give long-term insulation against moisture and attack from naturally occurring corrosive elements found above and below ground.As we know electrical power cables may be installed as permanent wiring within buildings, buried in the ground and run overhead or exposed.

Aluminum foil/strip  is used to manufacture the metal sheathing for electrical cables for construction and industrial markets. With its combination of strength, formability, and light weight, aluminum is the metal of choice for contractors and electricians. As a result, aluminum strip has replaced steel for many commercial, residential, and industrial applications.
