3 82 A 2 Layer Cable With Radius Ri 5mm And Outer Radius R 20mm Will Be Designed In The Design Of The Cable The Cost 1 (130.14 KiB) Viewed 63 times

3. 82 A 2-layer cable with radius ri-5mm and outer radius R=20mm will be designed. In the design of the cable, the cost of the conductor is minimum and the maximum voltage it can operate at is 100kv. While designing, it is $ desired that the insulators forming each layer should not be pierced. The properties of the insulators are requested in the table below. What should be the radius of r2 so that the cost is minimum since the cable is supplied without being punctured? Calculate the stress falling on the layers at radius 12 where the cost is minimum. Calculate the insulator cost of a cable of length 1 at radius r where the cost is minimum. 1. insulator Dielectric constant &1= 4 £2= 2 puncture resistance 100kv/cm 95kv/cm the unit cost 20000 TL/m2 50000 TL/m3 2. insulator r2=? U1=? U2=? Minumum insulator cost of 1m cable=?
