Definitions

• Invention particularly relates to cable production system providing reduction in diameter by means of round structure in twisting process by means of achieving a angular form of 120 ° in 3-core cables, 90 ° in 4-core cables, 72 ° in 5-core cables for conductors and round structure by combining cones together upon passing through twisting space formed between slab a and slab b in insulation production process.
• Today conductive cables are used to transmit electric energy from one point to another.
• the biggest novelty experienced after invention of and actively starting to use electricity is the change made in inner structure of electric cables.
• Use of copper wire in said cables as conductor is common because it is easy to find it.
• Basic components of an electric cable are conductivity and insulation. Conductor transmit current through cable and insulation protects electricity in the conductor. Further additional coatings are made to cables in order to protect and make use life longer.
• the material mostly as conductor in an electric cable is copper but in some cases aluminium can also be used.
• the first manufacture process of a conductor is wiring process. This includes reduction of copper wire diameter to the last diameter gradually in order to increases conductivity and reduce skin effect.
• Copper wires are delivered to cable factories in standard thickness and in bobbin. Copper wires delivered to factory in standard thickness and ready for processing are conveyed to thinning machines at factory subject to need or thickness of cable to be produced. Thinning machines contain rolling mill capable to be thinned from 1.8 mm to 0.2 mm. Copper wires of bobbin shape is processed at required thinness by processing at thinning machine. Copper wires thinned at desired thickness are sent to machine called tampering machine and hardness of the copper is softened here and brightness is examined. Copper wire undergoes tampering process in order to obtain bright color.
• Copper not undergoing tampering process is rigid. Copper wires delivered to factory in raw forms undergo stages such as thinning, softening and polishing and are made ready for processing. Thinness or thickness of the cable is fixed on basis of need. Copper wires of which operation is finished are sent to coating machine. Required chemicals are melted by heating according to feature of the product. After cables are cooled down at cooling machine, they are sent to a control system to check for any errors in coating of cable at a higher voltage machine. Chemicals used in coating of copper in cable manufacturing may show difference subject to area of use. If a cable to be laid under floor is to be manufactured, PVC-PE is used in outer coating of cable. Different chemicals are used in cables used in indoor or small house appliances.
• Type of chemicals in the coating part of cable varies because of causes such as humidity; dryness of the area where cable is laid If cable is to be laid in an area to taken strike, form of chemical to be used is produced in a resistant structure and at high temperature. Insulation material of high temperature resistance used in cables permits conductor to conduct more power from same area and an insulation of lower temperature resistance. Full length of cable is subjected to a voltage test for no failure in insulation coating. Electric coatings insulate signals transmitted through cable against potential external interactions. It also protects power cables in order to prevent intervention to adjacent signal circuits. Mechanic covers also called armor protects cable against stroke, rodents and other external damages arising from potentially damaging causes. In general an outer polymer coating is applied to protect cables. This coating is called outer sheath. The sheath protects conductors and insulation against outer factors such as humidity and mechanical aggressions that might affect electrical features.
