Alumoweld-Aluminum Clad Steel Wire(ACS Wire）
What is Alumoweld？
Alumoweld is an aluminum clad steel cord that has a wide range of applications in power transmission and communications. Specifically, It is often used as a ground wire for electrical transmission lines, since it offers the necessary electrical and mechanical properties.
Aluminum clad cord combines the electrical conductivity of aluminum with the strength of steel, making it an ideal material for energy transmission. The aluminum layer has good electrical conductivity and is able to effectively transmit current, while the steel core provides the necessary strength and rigidity to ensure that the strand maintains its stable performance in various environmental conditions.
Alumoweld is used as a grounding material in international power transmission projects, as 400kV lines, 220kV y 60kV. These cords not only meet the electrical requirements of the transmission project, They also have sufficient mechanical strength to resist natural forces such as wind pressure and ice loads..
Besides, Alumoweld strands are often used in conjunction with OPGW (fiber optic composite aerial ground cable) for the transmission of both communications and energy, with fiber optics inside the OPGW transmitting communication signals and aluminum-clad steel strands on the outside providing protection and support.
Composition and structure of Alumoweld
Alumoweld is made from two main materials: a steel core and an aluminum layer. The steel core provides the mechanical strength necessary for the wire to withstand high tensions and external forces, while the aluminum layer offers excellent conductivity and corrosion resistance.
Steel core: Alumoweld core is made of high strength steel. This steel core is crucial for the strength of the wire, as it allows it to withstand heavy loads and resist breaking under stress. The high strength steel used in Alumoweld is typically manufactured to withstand significant mechanical stresses, which is essential for applications where large spans or high voltage are required.
aluminum cladding: Surrounding the steel core is a layer of aluminum. This aluminum coating has several purposes. First of all, provides the cable with good electrical conductivity, essential for its role in power transmission and telecommunications. In second place, aluminum acts as a protective barrier against corrosion, especially in difficult environments such as coastal areas or regions with high levels of pollution.
The Alumoweld creation process involves a metallurgical union, in which aluminum bonds to the steel core at a molecular level. This process ensures that the aluminum coating adheres firmly to the steel, providing a uniform layer of protection and conductivity over the entire length of the cable.

Alumoweld Applications
The properties of Alumoweld make it suitable for a wide variety of applications, especially in industries where resistance, Durability and corrosion resistance are essential.
Electrical energy transmission: One of the main uses of Alumoweld is in overhead power transmission lines.. In these applications, the cable must traverse long distances between towers, often in adverse environmental conditions. Alumoweld's high strength allows it to maintain these distances without sinking or breaking, while its corrosion resistance guarantees a long service life, even in coastal or industrial areas.
Telecommunications: In the telecommunications sector, Alumoweld is often used as a messenger cable or as a reinforcing element in self-supporting cables.. Provides the necessary structural support for cables carrying fiber optics or other communication lines, ensuring these cables remain intact and functional over long distances.
Grounding systems: Alumoweld is also used in grounding systems for power distribution and transmission.. Its corrosion resistance is particularly advantageous in grounding applications., where the cable may be buried or exposed to moisture and other corrosive elements.
