Scope

Scope: This standard specifies the method for measuring the current-carrying capacity and temperature rise of copper conductor cables and aluminum/aluminum alloy conductor cables connected in series through copper-aluminum transition terminals when laid in air, including test equipment, test circuit layout, test requirements, test steps, result determination, and test reports. This standard applies to the current-carrying capacity and temperature rise tests of single-core copper conductor cables and aluminum/aluminum alloy conductor cables. Main technical content: 1.
