Abstract

In this article, a complex of calculations is presented for 6-10 kV cables with insulation made of crosslinked polyethylene and impregnated paper insulation. The article provides calculation formulas for: verifying cables under thermal resistance conditions during short-circuit, selecting the cross-section of the copper shield, selecting the cross-section of power cables based on permissible continuous currents of feeders (according to power consumption), verifying the fire resistance of power cables during short-circuit, and checking the cross-section of power cables based on economic current density. References to regulatory documents are also provided.
