Aluminized carbon steel wires
Aluminized carbon steel wires are developed as an alternative to traditional galvanized carbon steel wires. The aluminized coating is formed by chemical vapour deposition of aluminium on the surface of the steel wire. This produces a durable protective coating which prevents corrosion of the steel. Aluminized carbon steel wires are used primarily in the production of cable used in applications such as High Voltage (HV) transmission and distribution systems.
Aluminized carbon steel wires offer several advantages over traditional galvanized wires. Aluminium is a more effective corrosion inhibitor than zinc, meaning that the aluminized coating is more durable. Furthermore, the aluminium coating gives the wire better conductivity, creating less electrical resistance and increasing the efficiency of the cable. Additionally, aluminium is considerably lighter than zinc, which reduces the overall weight of the cable, making the cable more flexible and easier to transport and install.
Aluminized carbon steel wires are produced in a range of diameters and coatings, depending on the application for which the wire is intended. Wires for HV transmission and distribution systems are typically produced in 10mm to 40mm diameters and a range of aluminized coatings, depending on the voltage and power being transmitted. A thicker coating is usually required for high voltage applications in order to provide higher levels of protection. Commercial grade wires are usually produced in 2mm to 10mm diameters and a range of aluminized coatings, depending on the level of corrosion protection required.
In order to create the aluminized coating, the steel wire is first cleaned and then placed in a vacuum chamber containing aluminium vapour. Once inside the chamber, the vapour chemically reacts with the surface of the steel to form an aluminized layer. The thickness of the coating is determined by the amount of time that the steel wire is exposed to the vapour. The coated wire is then cooled before being removed from the chamber.
Aluminized carbon steel wires are highly versatile and can be used in a range of applications, both for high and low voltage purposes. The aluminized coating improves the performance and durability of the cable, making it an ideal choice for the production of power cables. The aluminized coating also increases the lifespan of the cable, ensuring a long and reliable performance.
