Insulation properties of aluminum foil for cables
We all know the widespread use and necessity of cables in electronics. Datorită utilizării pe scară largă a cablurilor și sensibilității lor inerente la energia electromagnetică, metoda de ecranare a cablului poate fi mai importantă decât specificațiile conductorului și ale mantalei.
În cablurile de comunicație, aluminum foil provides long-term insulation against moisture and corrosion from naturally occurring corrosive elements above and below ground. Aluminum foil also acts as an insulator against the magnetic and radio frequency fields associated with metal cables.
As the jacket of the fiber optic cable, the conductivity of the aluminum foil can test the integrity of the cable connection, acting as a "tracer" for the fiber optic cable.
Technical Specifications about aluminum foil for cable
- Grosime: 0.008-0.2mm
- Lăţime: 250-1200mm
- aliaj: 8011, 1050, 1060, 1235
- lighter in weight and more cost-effective than copper.
- Metoda de prelucrare: aluminum plastic composite is processed into a narrow strip
- Thicker film substrates provide higher dielectric and tensile strength. Thicker foil substrates provide higher conductivity and tensile strength, and lower signal attenuation.Tips: product width size is divided according to customers’ needs.The cable foil requires less oil on the surface, fara gauri, high mechanical properties, low overall quality requirements, but extremely strict length requirements.

The working principle of aluminum foil for cables
Foil shielding is an important way of shielding cables by wrapping the cable with a thin layer of aluminum foil and polyester backing for increased durability. The foil shield works in series with a tinned copper drain wire to ground the shield.
