8011 aluminum foil for cable belongs to 8000 series aluminum added with Fe-Si alloy elements. The alloy properties is more than 1% of the total alloying elements and have corresponding advantages. The thickness range of the aluminum foil for cable is 0.02mm-0.2mm, and the width is 300mm-1100mm or customized for the users. Aluminum foil for cable 8011 O manufacturers use aluminum-plastic composite method to coat high-voltage cables.
Because used for wrapping cable, the temper of the aluminum for cable 8011 should be soft (O). The aluminum foil for cable is made by attaching a special plastic film (0.058mm thick) to the upper and lower surfaces of the aluminum foil. There are two methods of attachment, dry attaching and wet attaching. The dry method uses a high temperature (200 ° C) roll to stick the film, the wet method is by glue bonding. Most of the current methods use dry methods. After attaching the plastic film, the film is peeled off from the aluminum foil by a special instrument to determine the degree of bonding of the plastic film. This measurement data is very important, and is called the peeling strength. According to the communication cable industry standard, the peeling strength should not be less than 6.13 N/cm, in addition, the heat sealing strength should not be less than 17.5 N/cm. The surface quality of aluminum foil for cable 8011 o manufacturers is the most important factor affecting the peel strength.
