# Significant cost savings can be achieved using CCA in lieu of COPPER
*for busbars in indoor installations at 35°C ambient temperature and 65°C bar temperature.
** Derating Factors:
– Temperature rise – Skin effect and skin depth – Proximity effect – No of bars in parallel | – Enclosure material – Creep resistance – Fatigue resistance – Reactance | – Vibration – Effect of coating – Heat loss – Convection, Radiation, Conduction – Short circuit: Electromagnetic forces, Thermal effects |
Electroplating Options
Tin – Effective protection against corrosion – Easy to solder – Temperature resistance up to 120 °C
| Nickel – High conductivity – Easy to solder – High temperature resistance (200 °C) | Silver – High corrosion resistance – Soldered under certain conditions – High temperature resistance (260 °C) |
