Enhanced are the service properties of electrical engineering strip profiles used at high electrical and mechanical loads in critical electric machines - rectangular copper buses (strength determination has been simplified, and surface finish evaluation accuracy has been improved), copper-cadmium trapezoidal collector strips (hardness has been increased, camber has been reduced, protrusions and marks on profile bases have been eliminated), and copper-silver collector strips (electrical resistance has been reduced, and stability of mechanical properties has been achieved).
