This document provides a practical guide for the methodical specification of high-voltage cables in accordance with International Standard IEC 183, “Guide to the selection of high-voltage cables.” It is intended to serve as a definitive resource for engineering and procurement professionals, ensuring that all critical parameters—from conductor size and insulation level to termination design—are systematically considered. Adherence to this guide facilitates the selection of appropriate cables, promoting safe, reliable, and efficient power system design.

The scope of this guide applies to the selection of high-voltage cables for use in three-phase alternating current systems operating at voltages exceeding 1 kV, as outlined in Clause 1 of the standard. While the principles are broadly applicable, this guide deals specifically with alternating current systems; direct current systems may be considered in a future publication.

To begin the selection process, it is essential to first establish a clear understanding of the foundational voltage definitions that govern cable and system compatibility.
