Aluminum, Aluminum Alloy and Aluminum-Steel cables, these are replacing hard copper line cables since the last century. ALL ALUMINUM CONDUCTOR CABLES (AAC) Bare Conductor Manufacturer Aluminium These cables are formed by several aluminum wires in concentric layers wired in opposite directions. (ACSR)Aluminum-Steel cables arose from the need to reinforce the aluminum cables by increasing the mechanical characteristics of the same, improving the coefficient of thermal expansion and ensuring a longer life of the driver. Since that time these drivers are the most universally employed in airlines. ACSR cables (Aluminum Conductor Steel Reinforced) are formed by wires of high purity hard temper aluminum, placed in concentric layers over a wire core or galvanized steel wire. COMPACTED ALUMINUM WIRE REINFORCED with steel core (AWG-MCM) This cable is a classic seven-wire formed by Circular section Aluminum-Steel, in which manufacturing process is given him a sectoral shape to the wires of the outer layer.
eliminating the existing gaps. Its main job is in medium and low voltage lines providing the following advantages: -Decrease in total diameter for the same effective section with consequent advantages in terms of wind action, ice sleeves, protection against humidity, etc. - Advantage to the connection, due to a larger contact surface Aluminum coated steel (Alumoweld type) is a bimetallic product with a pure aluminum coating on a high strength steel core, metallurgically bonded. The use of this type of wire is came of the conductivity that is higher than the galvanized steel and guarantees a corrosion resistance similar to the aluminum wire, so they can be used more safely than the ACSR in zones of industrial and maritime environments.
ALL ALUMINUM ALLOY CONDUCTOR / ALMELEC (AAAC) Almelec is an aluminum alloy (Magnesium and Silicon) used in conductors for power lines. The advantage of these cables against ACSR are: - Cheaper infrastructure due to: • Longer runs (less supports required) due to lower weight and high breaking load (arrow is less) • Better reuse of waste because it is a homogeneous cable - Easy installation • Greater surface hardness than aluminum (less shock sensitive) • Better tensile strength • Less weight, better handling of reels • Easy attachment of cable ends Almelec greased cables, both inside and outside, goes really well in installations near the sea and in areas with high pollution.
