Since 1909, the most common type of conductor used in the overhead transmission network for electricity has been around. Aluminum Conductor, Steel Reinforced (ACSR) has been around for more than a century, thus it is safe to assume that it is a well-known entity. Aluminum Conductor, Steel Supported (ACSS) was developed in the 1970s and has gained a comparable amount of notoriety since then. On the other hand, composite core conductors are relatively recent additions to the history of utility assets. However, after twenty years of use, the performance benefits of these transmission systems have become abundantly evident, as have the factors to be considered when deciding whether or not to use these systems when developing cost-effective transmission projects. The key advantages of using conductors with a composite core are a reduction in sag and an increase in capacity. Stranded carbon fiber cores are able to transmit up to twice as much power in a conductor of the same diameter as ACSR and ACSS, and they have a substantially lower thermal sag than both of those other types of cores. This benefit, along with others that will be discussed later, will inherently affect the design criteria for transmission projects New lines will have fewer supporting structures. Because of their low sag behavior, new transmission lines that use composite core conductors are able to traverse greater distances, which in turn reduces the number of support structures that are required. When designers work with longer span lengths, they are able to reduce the number of structures or make them shorter. As a direct consequence of this, the total expenses of the project in terms of its materials and right-of-way are greatly reduced. According to Charles Holcombe, manager of overhead systems and solutions at Southwire Co., "Composite cored overhead conductors enable designers to maximize line designs while simultaneously limiting sight lines and reducing the overall cost of the project." According to him, cutting down on the number of structures involved in a project in the western United States brought the overall cost down. It was necessary to completely reconstruct an aged transmission line using brand new support structures from the ground up.

Because the capacity requirements for the new line did not change, the design engineers were able to employ a conductor with a smaller diameter made of composite cores and increase the distance between support structures from 600 feet to 1,200 feet. Because of this, only one-half as many buildings were required for the new line, which resulted in a 15 percent reduction in the total cost of the project. Increased carrying capacity for lines that have been reconducted While alternative conductor solutions could necessitate a complete rebuild that includes the construction of pricey new buildings, composite core conductors make it possible for lines to be reconductored in order to increase the thermal capacity of the line. Simply switching from ACSR conductors to composite core conductors can increase capacity by up to twofold while also reducing sag in the cable. When a line needs to be improved for increased capacity, there is a large cost advantage to reconductoring with composite core conductors, according to Holcombe. "The cost advantage is enormous." "Instead of the enormous expenditures of creating new, larger foundations and structures for ACSR or ACSS, you invest a bit more by adding high-performance conductors onto the existing structures," he said. "This will allow you to save money." When there are distinct design challenges, there are also similar cost advantages that come into play. Holcombe describes a project in which riverbank soil erosion necessitated the relocation of a support structure further away from the river, which resulted in an increase in the length of the river crossing span from 1,290 feet to 1,840 feet. Increasing the length of the crossing would have caused the ACSR to sag more, which would have necessitated the construction of additional structures with wider foundations on both sides of the river. The design engineers decided to use a composite core conductor instead, which enabled them to bridge the distance without seeing an increase in sag. As a result, they were able to avoid having to completely rebuild the line while also reducing the overall cost of the project. Other considerations to take into account, When it comes to selecting conductors for transmission projects, installation requirements are a significant issue to take into consideration. Greater flexibility and improved bending tolerance are two benefits associated with the use of stranded composite core conductors in this context. In addition, workers that are familiar with installing ACSR or ACSS may be able to use the same tools, technology, and work procedures when installing composite cores. Stranded composite cores are not vulnerable to failing at a single spot due to their design. These cores are used in the construction of our overhead conductors." The end product is a conductor that is, compared to anything else available on the market, more robust and reliable.

When taking into consideration the expanding market for renewable energy in today's society, line losses are another factor of worry. Conductors with a composite core do not experience the losses caused by core magnetization, which are experienced by steel core conductors. The owners of wind farms and solar power plants that sell their generation into the transmission system suffer financial losses whenever there is a power loss. In the end, composite cores have proven themselves worthy of being included in the same category as the tried-and-true conductors of the industry. In addition, when the overall cost of the project is taken into account, the composite core solution will often win out over the tried-and-true workhorses in every category. Between the power plants and the people who use the electricity, there is a vast and intricate network of conductors that are used for transmission of the electricity to the final user. These networks, when combined, comprise a comprehensive transmission and distribution system, yet the functions of both the transmission and distribution systems are only slightly distinct from one another. The delivery of bulk power from producing stations to load centers and major industrial consumers who reside outside the economically viable service range of conventional primary distribution lines is the primary purpose of transmission systems. When it reaches the substations, the electricity is further reduced before being supplied to residential and business customers. The power can be transported via either an overhead system or a subterranean system. Both of these options are viable. Copper was typically utilized in the early days as the material for conductors on transmission and distribution lines. However, aluminum conductors have totally replaced copper conductors because to the significantly lower costs and lighter weight of aluminum in comparison to copper, which has comparable resistance. Aluminum Conductors come in a variety of forms, the most common of which are I All Aluminum Conductors (AAC), (ii) All Alloy Aluminium Conductors (AAAC), (iii) Aluminium Conductors Steel Reinforced (ACSR), and (iv) All Aluminum alloy conductor steel reinforced (AACSR). These are utilized in the Transmission and Distribution system, which is responsible for transporting the electrical energy created at the generating plant to the end customer. Conductors classified as AAC, AAAC, and ACSR are distinguished from one another primarily by the materials that they are made of. Aluminum obtained through electrolytic refining is used in the production of AAC, which must have a purity level of at least 0.7%. The material known as AAAC is an aluminum alloy, while the material known as ACSR is an aluminum alloy that has been reinforced with steel. Because ACSR Conductors are subject to galvanic corrosion, a new type of conductor known as AAC Conductors had to be invented as a result. Bus bars in substations often make use of AAC, particularly in urban regions where the spacing between supports is tight and the supports themselves are closer together. Because they have a strong resistance to corrosion, they find widespread application in environments prone to saltwater corrosion, such as coastal regions. The ACSR conductors are the ones that are utilized the most frequently for overhead transmission systems. On the other hand, the AACSR conductors and the Extra high strength ACSR conductors are the ones that are utilized for river crossings because their installation requires very lengthy spans.

Because of its high tensile strength as well as its balanced ratio of aluminum to steel in terms of weight and strength, ACSR can be used in situations where greater spans with less support are required. Altering the percentage of steel core in ACSR allows for the production of a range of various strengths. The ability of this form of conductor to provide the appropriate strength without sacrificing ampacity is the primary benefit of using this type of conductor. On the other hand, AAAC possesses a larger mechanical resistance than AAC does, which enables it to be used as a bare overhead conductor on aerial circuits for power transmission and distribution lines. In comparison to AAC, it possesses superior sagging qualities as well as a higher strength-to-weight ratio. It also has less resistance, which contributes to its lighter overall weight, giving it an edge over the ACSR. In addition, the protection against corrosion offered by a AAAC conductor is superior to that offered by an ASCR conductor. As a result of these factors, AAC and ACSR are generally considered less desirable conductors than AAAC is The federal government and state governments are actively working to ensure that power can be reached in every nook and cranny of the nation. Because of this significant commitment and initiative for rural electrification, every single dwelling in a remote village will soon have electricity. In order to guarantee that all parts of society have access to power, numerous changes have been put into motion. Because of this initiative, there has been a significant rise in both the demand for conductors and the spectrum of their applications, which has helped to boost the business of enterprises that manufacture conductors.
