Cable aluminum foil quality requirement
Cable aluminum foil is also called as aluminum cable foil, aluminum for cable and cabel aluminum foil strip. The cable aluminum foil is an composite material, after the plastic film is coated on one side or both sides of the aluminum foil, an aluminum-plastic composite foil is formed. The cable aluminum foil uses the principle of hermeticity and shielding of the aluminum foil. It is wrapped on the outside of the signal transmission wire and serves as a shield, which can play a very good signal shielding effect. 1145 grade industrial pure aluminum is usually used in aluminum cable foil.
In general, the overall requirements for the quality of aluminum foil are not very high, only small amount of oil on the surface and no holes are enough. Because the surface quality of aluminum foil is the most important factor affecting the peel strength, its main surface quality problems are oil spots, corrosion, and peroxidation. However, cable aluminum foil has higher requirement on the length and mechanical properties. In terms of length, the length of the cable aluminum foil is only allowed to be longer but not shorter. This requires careful calculations during the casting of the billet, the billet should be kept as much as 10 or 12 times the length of the customer’s requirement, and plus an additional 3% error. In terms of mechanical properties, the setting standard of the aluminum cable foil in the communication cable industry is not high, but most customers require the strength to be greater than 70 MPa or 80 MPa.
