VERIFICATION OF THE COMPLIANCE OF ACTUAL CABLE CORE CROSS-SECTIONS WITH THEIR NOMINAL VALUES

A standardized series of nominal cross-sections for wires and cables used in power supply systems is presented. The permissible continuous current loads for cables with copper and aluminum conductive cores insulated with polyvinyl chloride compounds are provided. The requirements for conductive wires of any purpose are listed. An analysis of the current-carrying capacity of cables has been conducted. A verification of cable samples for compliance with standard cross-sections was performed. Deviations of the actual cross-sections of the examined samples from the standard nominal values are shown
