In this article, we will be looking first into the wire and cables in general and then some information regarding the specification of the 33kv industrial cable with the XLPE insulation. One of the most essential elements of overhead power wires is the aerial bundling of individual wires. When installing an overhead wire, it is just as vital to select the appropriate type of overhead cable as it is to select an economically viable conductor size and an economically viable transmission voltage. The following characteristics are necessary for an effective conductor: A high degree of conductivity Excellent tensile strength for withstanding pressure from mechanical sources Reasonably priced without sacrificing many of the product's other desirable qualities A lower total mass when compared to its volume Materials used in overhead cables and their purposes Copper was the material of choice for making overhead cables in the beginning, but aluminum has since taken its position due to its lower cost and lower weight in comparison to copper conductors of the same resistance. The following is a list of different types of material that are considered to be good conductors. 
Copper wires in the ceiling Copper has better electrical conductivity and stronger tensile strength than other materials, making it ideal for use in overhead wires. Because of this, hard-wired copper is an excellent option for use in overhead wires. Copper has a high current density, which translates to a higher current-carrying capacity per unit of cross-sectional area. This property is referred to as the conductivity of copper. As a consequence, the copper conductor has a cross-sectional area that is not particularly large. In addition to this, copper has a long lifespan. However, because of its high price and limited availability, copper is only occasionally utilized for the wiring of electricity wires. Aluminum air wire Aluminum has a conductivity that is approximately sixty percent lower than copper. This indicates that in order to maintain the same resistance, the diameter of the aluminum conductor must be approximately 1.26 times larger than the diameter of the copper conductor. On the other hand, the weight of aluminum conductors is approximately half that of copper conductors that are equivalent. Aluminum also has a lesser tensile strength than copper does, which is another reason why aluminum is less commonly used. Copper is superior to aluminum in many respects, including cost, electrical conductivity, tensile strength, weight, and many more. Aluminum also has fewer environmental impacts than copper. As a result, aluminum is frequently utilized in the production of air conductors. 
Cadmium copper aerial cable Copper-cadmium alloys have anywhere from 98 to 99% copper and as little as 1.5% cadmium by weight. Copper's tensile strength is increased by around 50% when just 1% cadmium is added to the mix, although the metal's conductivity is only reduced by approximately 15%. Because of this, copper-cadmium conductors are suitable for usage across extraordinarily large spans. However, because cadmium is so expensive, the use of such conductors might not be cost-effective in many situations. Other types of materials that are utilized during the production of overhead cables There are a wide variety of additional metals and alloys that are also capable of conducting electricity. Silver is more readily available than copper, but because of its high price, it is rarely used in everyday applications. Conductors can also be made out of galvanized steel in some applications. Steel conductors are not appropriate for the effective transmission of electricity due to steel's low electrical conductivity and very high tensile strength. Despite steel's very high tensile strength, steel is a very strong material overall. Phosphor bronze and other high-strength alloys are also often employed under conditions that are considered to be extremely harsh. 
Different kinds of cables for the ceiling As was discussed before, aluminum conductors provide a number of advantages over copper conductors, including superiority in terms of cost, electrical conductivity, tensile strength, weight, and other characteristics. Aluminum conductors have totally taken over the role of copper conductors in power cables as a result of their significantly lower prices and significantly lower weights. The following is a list of the four most popular kinds of overhead wires that are utilized for overhead transmission and distribution in order to move electricity from power plants to its final consumers. In general, twisted cables or conductors are used for all sorts of overhead cables or conductors since doing so increases their flexibility. Solid wire is difficult to deal with except for very small cross-sections because of its lack of flexibility. 
AAC: Aluminum Conductor AAAC: Aluminum alloy conductor ACSR: Aluminum conductor, steel reinforced Aluminum conductor, reinforced alloy, abbreviated as ACAR AAC overhead cables are appropriate for use at low voltages, ranging from 1 to 32 kV, and in situations in which the current poles are situated in close proximity to one another. ACSR and AAAC power cables are utilized for medium and high voltages, respectively, when the distance between the current poles is significant. In order for ACSR cables to be able to sustain greater tensile forces, the non-annealed aluminum used in their construction is wrapped in predetermined lengths on high-carbon galvanized steel wire. The structure of aluminum air cables is typically insulated with black polyethylene (XLPE). The thickness of CC cables is 3 millimeters, the thickness of 20 KV CCT cables is 5.5 millimeters, and the thickness of CCT cables that are 33 KV is 8 millimeters.
