The UPB/kg price of aluminum with a conductivity of 61% used in
energy transmission in a country has changed quadratically between
2010 and 2020. With the help of this curve, the aluminum price in
2015 was 180 UPB/kg and the aluminum price in 2020 was 450 upb/kg.
Again, the price change of electrolytic copper, which is used in
energy transmission, between the years 2010-2020 has been in the
form of an exponential function. The aforementioned price increase
trends continued in 2021 as well. a) In 2021, find the difference
(UPB/phase.meter) between the conductor costs of two cable types,
one with a 1000mm2 3-core aluminum conductor and the other with a
1000mm2 single-core copper conductor. Specific weight; 2.7x10^-3
kg/m.mm2 for aluminum and 8.9x10^-3 kg/m.mm2 for copper b) 13.8 kV
4500 kVAr 3-phase shunt reactor was prepared in two different
types, both with aluminum conductor and with copper conductor.
While the current density is 1.1 A/mm2 and the spir (turning)
number is 230 in the aluminum conductor design, the current density
is 2.3 A/mm2 and the spir number is 170 in the copper conductor
design. How many UPB is the difference between the costs of 1 meter
of aluminum and copper spins?
