The surface of the aluminum foil is covered with plastic. The film is cut into several small strips and supplied to the cable factory in a reel shape.
The cable foil is made by attaching a special plastic film (0.058ມມຫນາ) on the upper and lower surfaces of 0.15mm-0.20mm ແຜ່ນອາລູມິນຽມຫນາ. There are two methods of attaching: dry attaching and wet attaching. The dry method uses a high temperature (200℃) roll pressing method to attach the film; the wet method uses glue. ປັດຈຸບັນ, most of them use dry methods. After attaching the plastic film, use a special instrument to tear off the film from the aluminum foil to determine the degree of adhesion of the plastic film. This measurement data is very important and is called peel strength. According to the communication cable industry standard (code YD/T723.2-94), the strength should not be less than 6.13N/cm; ເພີ່ມເຕີມ, the heat sealing strength should not be less than 17.5N/cm. The surface quality of aluminum foil is the main factor that affects the peeling strength. The main surface quality problems are oil spots, corrosion, and over-oxidation.
The cable foil uses the airtightness and shielding properties of aluminum foil, and is coated with plastic film on one or both sides to form an aluminum #plastic composite foil, which is used as a cable shield. The cable foil needs to have a small amount of oil on the outside, no holes, and high mechanical properties. ເວົ້າໂດຍທົ່ວໄປ, the length of the cable aluminum foil is extremely strict.
Aluminum foil is commonly used as a cable shielding material for a number of reasons, including its effectiveness against electromagnetic interference (EMI) ແລະການລົບກວນຄວາມຖີ່ວິທະຍຸ (RFI), ຄວາມຍືດຫຍຸ່ນ, ແລະປະສິດທິພາບຄ່າໃຊ້ຈ່າຍ. Here are some key reasons why aluminum foil is used in electrical cables:
EMI and RFI Shielding: Aluminum foil provides excellent electromagnetic interference (EMI) ແລະການລົບກວນຄວາມຖີ່ວິທະຍຸ (RFI) shielding properties. It acts as a barrier that reflects and absorbs electromagnetic waves, preventing them from penetrating the cable and interfering with the signals carried by the inner conductors.
ຢືດຢຸ່ນ: Aluminum foil is highly flexible and can conform to the shape of the cable, making it suitable for a variety of cable designs and configurations.
ນ້ຳໜັກເບົາ: Aluminum foil is a lightweight material, and using aluminum foil as a shield does not significantly increase the weight of the cable.
ຄວາມຕ້ານທານຕໍ່ການກັດກ່ອນ: Aluminum foil has natural corrosion resistance due to the thin oxide layer formed on its surface.
