Cable Aluminium strip Foil
Aluminum strip foil for cable is a composite product of Insulation Aluminium Foil, and it is also composite aluminum strip foil. It can protect cables from corrosion and shielding signals from leakage. Due to the high sealing and shielding performance of aluminum foil, the aluminum plastic foil which is made up of a plastic film on one or two sides, is an ideal cable protection layer. The aluminum foil for cable is usually made from 1145 aluminum alloy or 8011 aluminum alloy with the thickness of 0.10mm, 0.15mm or 0.2mm. The width is 10mm to 600 mm, the length requires can be customized, generally 1100mm or 2100mm.
The quality requirements of insulation Aluminium Foil for cable 8011 o are mainly that the surface is with less oil, no holes and has higher mechanical properties. At present, advanced cold rolling mills, universal mills and aluminum foil roughing mills can produce insulation Aluminium Foil for cables. After continuous casting and rolling, hot rolling, cutting and thorough annealing, according to the length and short of the user, the cable aluminum foil is divided into small roll supplied to cable foil composite factory, and then press plastic film on the aluminum foil, and cut into small strip shaped supplied to cable factory. Because this kind of composite aluminum foil is has light quality and good effect of protective barrier, it is becoming more and more popular in the market

The barrier properties and heat reflectivity of aluminium foil are widely used in building panels to improve insulation performance in modern building systems.
Key features
- Aluminium strip Foil is used as a skin for heat-insulating and incombustible materials to provide high performance insulation for pipe work and ducting.
- The adhesive tape used to secure the laminated material is based on aluminium foil or its reflective surface, corrosion-resistance and long life.
- In electrical cables, aluminium foil helps give long-term insulation against moisture and attack from naturally occurring corrosive elements found above and below ground.
- Aluminium strip Foil also acts as an insulator against the magnetic and radio frequency emissions associated with electrical cables.
- As a sheath for fiber-optic cables, Aluminium strip Foil uses its electrical conductivity to act as a “tracer” to enable testing of the integrity of cable links – as well as helping to provide the long-term protection every cable needs.
- In fire walls for vehicles and fireproof doors and building panels, aluminium foil stops access to the oxygen required to support flames.
