The cable foil is an aluminum foil composite material, and after being coated on one side or both sides of the aluminum foil, an aluminum-plastic composite foil is formed. The cable foil utilizes the principle of airtightness and shielding of the aluminum foil, and is wrapped around the signal transmission wire to serve as a shield for the cable, which can provide a good signal shielding effect.

Cable foil has high requirements on length and strength. In general, the overall quality requirements of the foil foil for the aluminum foil material are not very high, only the surface with less oil, no holes can be. Because the surface quality of aluminum foil is the main factor affecting the peel strength, the main surface quality problems are oil spots, corrosion, peroxidation and the like. However, cable foils have higher requirements on length and mechanical properties.

In terms of length, the length of the cable aluminum foil is only allowed to be longer and not allowed to be short. This requires careful calculation of the billet when casting, and the billet should be kept as long as 10 or 12 times the length of the customer's demand, plus an additional 3% error; in terms of mechanical properties, that is, strength, The standard setting for cable foils in the communications cable industry is not high, but most customers require cable foil strengths greater than 70 MPa or 80 MPa.
