Electric cables - Calculation of the current rating - Part 1-2: Current rating equations (100 % load...
IEC 60287-1-2:2023 provides a method for calculating the eddy current losses in the metallic sheaths of single-core cables arranged as a three-phase double circuit in flat formation. The sheaths are bonded at one point or are cross-bonded so that there are no significant sheath circulating currents. Where metallic sheaths are bonded at both ends there are significant circulating currents which…
Twinax cables for digital communications - Part 1: Generic specification
IEC 62783-1:2023 specifies definitions, requirements and test methods of twinax cables used in digital communication systems: computer rooms, data centres, servers, etc. These cables are intended to be used indoors.
This document details the requirements and transmission characteristics for single twinax elements as well as multiple twinax elements within the same sheath, i.e. “twinax cable”.…
