    Aluminum conductors
    Scope of the invention
    This invention generally relates to conductors and in particular to aluminum alloy conductors suitable for use in high voltage cables.
    Background of the invention
    Aluminum offers a higher conductivity per mass than copper, making it a common choice in electrical conductors for a variety of applications, such as high-voltage cables. Depending on the applications, cables can be manufactured purely on the basis of aluminum conductors (eg AAC or AAAC), or as a combination of aluminum conductors around a variety of cores, such as around a steel (eg ACSR, ACSS), carbon fiber composite (eg. ACCS), Aluminum oxide fiber composite (eg ACCR) or invar (eg TACIR) core. Composite core aluminum conductors (ACCS), in which the conductors are made of soft pure aluminum, currently offer an interesting combination of properties in the form of a light cable with high conductivity and low thermal expansion. The low thermal expansion in turn allows a higher operating temperature; combined with the increased conductivity, a considerable increase in capacity of the cable can hereby be achieved. Nevertheless, the composite core is rather elastic, which makes the cable easily bend under load. This cable is therefore not very suitable for use in areas where wind or icing are relatively common and considerable.
    Aluminum conductors reinforced with steel (ACSR), in which the conductors consist of hard pure aluminum, are also known. These offer a considerably higher tensile strength and are therefore more resistant to load; the conductivity, on the other hand, is lower than for soft pure aluminum and the thermal resistance is considerably limited, so that these cables have a lower capacity.
    Aluminum alloys are also known which lead, for example, to conductors with improved thermal resistance, at the expense of a decrease in conductivity. For example, hard aluminum / zirconium alloys are known with, typically, a comparable tensile strength as hard pure aluminum and a high thermal resistance comparable to or higher than soft pure aluminum. These, on the other hand, have a conductivity lower than both pure forms. Specific combinations of these properties are specified for aluminum / zirconium alloys in the IEC62004 version 2007 standard (specifically ATI and AT3 alloy of this standard).
    There is room for aluminum alloy conductors that provide various desirable properties without compromising the properties also obtained by conductors based on annealed or non-annealed pure aluminum.
    Summary of the invention
    It is an object of embodiments of the present invention to provide better conductors based on aluminum alloys.
    It is an advantage of embodiments of the present invention that conductors are provided based on specific aluminum alloys, which have better properties than conductors made with annealed or non-annealed pure aluminum.

    It is an advantage of embodiments according to the present invention that an aluminum conductor with a higher conductivity and higher thermal resistance can be obtained without sacrificing the tensile strength, compared to hard pure aluminum.
    It is an advantage of embodiments according to the present invention that an aluminum conductor with an even higher thermal resistance can be obtained, without sacrificing the conductivity or tensile strength, compared to hard pure aluminum.
    It is an advantage of embodiments of the present invention that the alloys ATI and AT3 from the IEC62004 version 2007 standard can be achieved or even improvements over the standard can be achieved.

    Detailed description of illustrative embodiments
    The present invention will be described with respect to particular embodiments and with reference to certain drawings, however the invention is not limited thereto but is limited only by the claims. The drawings described are only schematic and not limitative. In the drawings, the dimensions of some elements may be increased and not drawn to scale for illustrative purposes. The dimensions and the relative dimensions sometimes do not correspond to the current practical implementation of the invention.
    Furthermore, the terms first, second, third and the like are used in the description and in the claims to distinguish similar elements and not necessarily for describing an order, neither temporally, spatially, or in any order or any other manner. It is to be understood that the terms used in this manner are interchangeable under suitable conditions and that the embodiments of the invention described herein are capable of operating in a different order than described or shown herein.

    It should be noted that the term "contains", as used in the claims, is not to be construed as limited to the means described thereafter; this term does not exclude other elements or steps. It can thus be interpreted as specifying the presence of the referenced features, values, steps or components, but does not exclude the presence or addition of one or more other features, values, steps or components, or groups thereof. Thus, the scope of the term "a device containing means A and B" should not be limited to devices consisting only of components A and B.

Rather, as the following claims reflect, inventive aspects lie in less than all features of a single prior disclosed embodiment. Thus, the claims following the detailed description are hereby explicitly incorporated into this detailed description, with each standalone claim as a separate embodiment of this invention.
    Furthermore, while some embodiments described herein contain some, but not other, features included in other embodiments, combinations of features of different embodiments are intended to be within the scope of the invention, and constitute various embodiments, as would be understood by those skilled in the art .

    Numerous specific details are presented in the description provided here. In any event, it is understood that embodiments of the invention can be practiced without these specific details. In other instances, well-known methods, structures and techniques have not been shown in detail to keep this description clear.
    As used herein, the international annealed copper standard (IACS) is an electrical conductivity unit relative to a standard annealed copper conductor. A conductivity of 100% IACS corresponds to 5.80x107 Siemens per meter at 20 ° C.
    As used herein, the thermal resistance, tensile strength and conductivity properties of an aluminum conductor, which can be obtained as described in the IEC62004 standards.
    As used herein, a soft aluminum conductor is an aluminum conductor in an annealed condition. This means that the heat treatment has been carried out in such a way that the elongation in the conductor is high, such as more than 15%, for example more than 20% and even more than 40%. A soft aluminum conductor typically has a low tensile strength, such as 100 MPa or less, and a high conductivity, such as more than 61%, for example more than 61.5% or even up to 63%. As used herein, a hard aluminum conductor is an aluminum conductor that is not in an annealed condition.
    As used herein, the composition ratios for a conductor are always expressed in percent by weight% (m / m).
    As used herein, a conductor means a single wire. Twisting conductors, whether or not around a core, results in a bare cable. Such cables can, for example, be used as high voltage cables.
    In a first aspect, the present invention relates to a conductor suitable for use in a high voltage cable. The conductor consists of an aluminum alloy, in which the aluminum alloy is 0.006 to 0.027% (m / m), preferably 0.008 to 0.025% (m / m), of a group 3, 4, 5 or 6 element or a lanthanide and in which the conductor has undergone heat treatment such that the conductor has a conductivity of 61% IACS or more. Within the present invention it was surprisingly found that based on these aluminum alloys, after an appropriate heat treatment, an aluminum conductor with a relatively high conductivity can be obtained. For example, this relatively high conductivity can be equal to or higher than that of hard pure aluminum (61% IACS), up to and including the conductivity of soft pure aluminum (63% IACS); depending on the specific alloy composition and specific heat treatment selected. When reference is made to pure aluminum, reference is made to technically pure aluminum with at least 99.7% aluminum. This can be used to advantage in the preparation of various soft or hard aluminum conductors with improved properties, i.e. with higher conductivity, tensile strength and / or thermal resistance compared to known aluminum conductors. Furthermore, in certain embodiments, the improvement of one or more of these properties can be advantageously obtained without sacrificing the other properties, again compared to already known aluminum conductors.
    In embodiments, the aluminum alloy may contain 99.5% (m / m) or more, preferably 99.65% (m / m) or more, aluminum. A higher mass fraction of aluminum typically advantageously leads to a conductor with a higher conductivity.
    In embodiments, the aluminum alloy may further also contain 0.00 to 0.02% (m / m), preferably 0.01% (m / m), yttrium and / or erbium. A small mass fraction of yttrium and / or erbium typically advantageously leads to a conductor with a higher thermal resistance. In embodiments of the present invention, yttrium and / or erbium can both be used as the single element, in combination with each other or in combination with one or more elements of groups III, IV and V of Mendeljev's table.
    In embodiments, the aluminum alloy may further also contain 0.1 to 0.3% (m / m), preferably 0.12 to 0.18% (m / m), iron. A small mass fraction of iron typically advantageously leads to a higher tensile strength and recrystallization temperature, with only a small influence on conductivity.
    For example, in embodiments, the thermal treatment may include treatment at a temperature of 185 to 315 ° C for 12 to 24 hours. Depending on the chosen temperature, a soft or a hard conductor can be obtained advantageously; a soft conductor typically has a higher conductivity but a lower tensile strength than a hard conductor. The duration of this thermal treatment, up to 24 hours, is advantageously considerably shorter than typically necessary for known hard aluminum conductors with high thermal resistance, for example, the thermal treatment can be up to 6 days.
    In embodiments: - the group 3 element may be scandium or yttrium or a combination thereof, - the group 4 element may be titanium, zirconium or hafnium or a combination thereof, - the group 5 element may be niobium or tantalum or a combination thereof, and - the lanthanide lanthanum, cerium, praseodynium or erbium or a combination thereof.
    In embodiments, this guide may have a cross-section of a rather oval shape, such as circular formation (FIG. 1.a). In other embodiments, this conductor may have a cross section with a more angular shape, such as previously trapezoidal (FIG. 1.b). A more angular cross-section can advantageously lead to a cable with a better space filling.
    In the table below, some preferred embodiments of the aluminum conductors of the present invention are compared with known aluminum conductors.
    In a first preferred embodiment, the aluminum alloy may contain 0.008 to 0.010% (w / w) zirconium, and the thermal treatment may contain a treatment at a temperature of 270 to 290 ° C for 12 to 24 hours. Furthermore, the aluminum alloy can also be 0.00 to 0.02% (m / m) yttrium and / or erbium, such as 0.01% (m / m) yttrium, and 0.1 to 0.3% ( m / m), such as 0.12 to 0.18% (m / m), of iron. In this way, it is advantageous to obtain soft aluminum conductors with a considerably higher tensile strength compared to pure soft aluminum conductors (± 50% higher), with the same conductivity (63%) and high thermal resistance (180/220). These conductors can, for example
    advantageous in high-voltage cables of the 'aluminum core with composite core (ACCC ™)' or 'steel-assisted aluminum conductors (ACSS)' type, whereby in both cases the tensile strength of the cable, and thus the resistance to bending under load, is increased by the higher tensile strength of the soft aluminum conductor.
    In a second preferred embodiment, the aluminum alloy may contain 0.013 to 0.020% (m / m) zirconium, and the thermal treatment may contain a treatment at a temperature of 185 to 225 ° C for 12 to 24 hours. Furthermore, the aluminum alloy can also be 0.00 to 0.02% (m / m) yttrium and / or erbium, such as 0.01% (m / m) yttrium, and 0.1 to 0.3% ( m / m), such as 0.12 to 0.18% (m / m), of iron. In this way, hard aluminum conductors can be obtained advantageously with properties corresponding to ATI AlZr conductors, but with a higher conductivity (61.5% vs 60%). For example, these conductors can be advantageously utilized in ACCC ™ type high voltage cables, further increasing the tensile strength of the cable even more than is the case for the aforementioned aluminum conductors of the first preferred embodiment, at the expense of a reduction in the conductivity (61.5% vs 63%). On the other hand, these conductors can also be used advantageously in high-voltage cables of the 'steel-reinforced aluminum conductors (ACSR)' type, for example, in which the thermal resistance and the conductivity of the cable are increased compared to pure hard aluminum.
    In a third preferred embodiment, the aluminum alloy may contain 0.020 to 0.025% (m / m) zirconium, and the thermal treatment may include a treatment at a temperature of 200 to 240 ° C for 12 to 24 hours. Furthermore, the aluminum alloy can also be 0.00 to 0.02% (m / m) yttrium and / or erbium, such as 0.01% (m / m) yttrium, and 0.1 to 0.3% ( m / m), such as 0.12 to 0.18% (m / m), of iron. In this way, hard aluminum conductors can be obtained with the same conductivity as pure hard aluminum (61%), but with a higher temperature resistance. Alternatively, these conductors can also be compared with the current aluminum alloys with high thermal resistance, the conductors according to this third preferred embodiment having a thermal resistance between that of ATI and AT3 AlZr conductors (180/220 vs 150/180 and 210/240) but with higher conductivity (61% vs 60%) These conductors can, for example, be used again advantageously in high-voltage cables of the ACCC ™ type, whereby the tensile strength of the cable is further increased, again even more than is the case for the aforementioned aluminum conductors of the first preferred embodiment, at the expense of a decrease in conductivity (61% vs 63%). On the other hand, these conductors can also be advantageously used, for example, in high-voltage cables of the ACSR type, whereby the thermal resistance is further increased, even more so than for the aforementioned aluminum conductors of the second preferred embodiment, the conductivity, and the same conductivity as pure hard aluminum. The latter can also be an advantage in practice since it allows exchanging existing pure hard aluminum conductors for aluminum conductors according to the present invention, without modifications in the rest of the system.
    It should be noted that temperature tolerances may further depend on composition, trace elements and, for example, variations in oven type. The person skilled in the art can take into account a more specific characterization, depending on local variations such as the temperature process, the packaging, the diameters of the wire, the exact composition, etc. where necessary.
    In a second aspect, the present invention relates to a use of the conductor of the first aspect in a high voltage cable. In embodiments, the guide may be similar to embodiments of the first aspect.
