Short Circuit Testing
CUPONAL has been successfully tested for short circuit performance in many applications by authorities such as: ASTA (The Association of Short Circuit Testing Authorities); KEMA (NV tot van Elektrotechnische Materialen); Electrisches Prüfamt, München
Metal Forming Characteristics
CUPONAL is easy to bend, having less springback than copper. The relevant data sheet should be consulted for recommended bending radii. Cuponal is also easy to drill, cut and punch.
Reduce costs by up to 40%!
A Cuponal bar can save as much as 40% compared with a copper bar of equal dimensions.
Reduce weight by up to 60%!
The relative density of Cuponal vs copper results in the mass of Cuponal busbars being only 41% of that of a copper bar of equal dimensions.
Smooth out cost fluctuations!
Over a 6 month period, the price of copper busbar can change by as much as 25%. The equivalent variation in the price of Cuponal would be just 7%.
Reduce the cost of your inventory!
Without affecting its production equivalent. X metres of Cuponal cost less than X metres of copper, therefore covering the same usage for less inventory value = lower financing costs.
