Bare Conductor Manufacturer Aluminium The aluminum used to produce these cables is from first fusion, with a minimum of 99.5% aluminum ensuring with this purity a high resistance to corrosion. These cables are suitable in areas with high humidity and in places with high air pollution. These cables can be supplied greased, using a chemically stable grease and neutral against aluminum.
The range of bare cables for airlines is divided, depending on their use, in:
- Bare Conductor
- AAC Conductor
- AAAC Conductor
- ACSR Conductor
- AACSR Conductor
- ACSR / AW Conductor
- TACSR Conductor
- ACAR Conductor
- ACSS Conductor
- ACSS / TW Conductor
- ACS Conductor
- GSW Conductor
- ACCC Conductor
These are mainly made of Aluminum, Aluminum Alloy and Aluminum-Steel cables, these are replacing hard copper line cables since the last century.
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
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.
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
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.
