The era of cable aluminum foil is coming

Introduction to Cable Aluminum Foil
The cable aluminum foil is an aluminum foil composite material, and after being coated on one side or both sides of the aluminum foil, an aluminum composite foil is formed. The cable aluminum foil utilizes the sealing and shielding principle 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 aluminum foil requirements
In general, the overall requirements for the quality of the aluminum foil material of the cable aluminum foil are not very high, only the surface with a small amount of oil, no holes can be. Because the surface quality of cable aluminum foil is the most important factor affecting the peel strength, the main surface quality problems are oil spots, corrosion, and peroxide.
However, cable aluminum foil has higher requirements on length and mechanical properties. In terms of length, the length of the cable 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 for cable aluminum foils in the communications cable industry is not high, but most customers require cable foil strengths greater than 70 MPa or 80 MPa. The reason the customer considers this is mainly to prevent cracking when the film is coated, especially when winding on the cable. Because the plastic film is cut into several strips, the narrowest is 12mm. There may be slight cracks or burrs when cutting. When using, it should be wrapped with tension. If there is a slight defect, it will break due to stress concentration.
Cable aluminum foil alloy
Cable aluminum foil is commonly used in 1235 aluminum foil and 8011 aluminum foil. The temper is mainly in O state. The product quality is high and the performance is stable, which is well received by the market.
Cable aluminum foil manufacturer Henan Mingtai
Cable aluminum foil manufacturer Henan Mingtai always adheres to the customer-centered process, paying special attention to the process standard of cable aluminum foil in the production process, strictly controlling the quality and strength of cable aluminum foil, so that the product popularity and market coverage are expanding, and the sales volume is steadily increasing. improve. More attention is paid to comprehensive control of the chemical composition, dimensional tolerance, surface quality and mechanical properties of aluminum foil, and conscientiously implement the corresponding standards to ensure the quality of the products.
