Abstract

Reliability of electrical contact connections considerably determines working capacity and fire-safety of electrical installations. Basing on consideration of physicomechanical properties and microgeometry of contact-details surfaces main trends of contact connections improvement, first and foremost, aluminium conductors, are specified: application of electroconductive lubricant, knurling contacts-details surfaces.
