Aluminum strip for cables
What is an aluminum strip? Aluminum strip is a product obtained by forging and shearing from deep-processed raw materials of aluminum coils/plates. It has good characteristics and applications. Among them, one of the most common uses of aluminum tape is for cables. The main function of aluminum tape is to reinforce and protect the outer protective layer of the cable.

Aluminum strip protects cables
Why is aluminium used in power cables? Cable aluminum strip is a material widely used in the cable industry, mainly used for shielding and insulation of cables. Since cables need to withstand a certain amount of tension and pressure, they are prone to damage and wear under the influence of the external environment. As a material with high strength and corrosion resistance, aluminum tape can effectively reinforce the outer protective layer of the cable, improve the tensile strength and pressure resistance of the cable, thereby protecting the internal structure of the cable from damage.

Advantages of aluminum strip for cables
Aluminum strip is an ideal material for cables due to its high strength-to-weight ratio, excellent corrosion resistance and the ability to be easily shaped to fit the cable. In cable applications, aluminum strip for cables is usually wrapped in a spiral around the cable and is a protective layer used to shield the cable from external factors such as mechanical damage, moisture and other environmental hazards, providing an additional layer of protection to prevent damage.

Electromagnetic shielding of cable aluminum strips
In addition to protecting cables, aluminum strips can also act as electromagnetic shielding. During the transmission process of cables, the flow of current will generate a magnetic field, which may cause interference to surrounding electronic equipment. As a good electromagnetic shielding material, aluminum strip can effectively block the propagation of electromagnetic waves and reduce the interference of electromagnetic radiation to surrounding equipment.
Conductivity of aluminum strip cable
Aluminum is a good conductive material, so aluminum strips can also improve the conductivity of cables. Applying aluminum strip for cables can increase the conductivity of current, reduce the resistance of the cable, and improve the transmission efficiency of the cable.
Fire resistance of cable aluminum strips
Aluminum strips also have certain fire-retardant properties. Because aluminum strips have a high melting point and thermal stability, they can prevent the spread of fire to a certain extent. Therefore, in some situations that require high fire resistance, aluminum strips are widely used in the manufacture of cables to improve the safety performance of cables.
Aluminum strip for cables corrosion protection
Aluminum strips can also protect against corrosion. Aluminum strips have high corrosion resistance and can effectively resist the erosion of chemicals such as acids and alkalis, extending the service life of cables.
