T/CEEIA 467-2020 Guidelines for the electrical gap and creepage distance values for equipment with rated voltages ranging from AC 1000V to 2000V and DC 1500V to 3000V, as well as requirements for solid insulation
T/CEEIA 467-2020 Guidelines for the electrical gap and creepage distance values for equipment with rated voltages ranging from AC 1000V to 2000V and DC 1500V to 3000V, as well as requirements for solid insulation
Basic Information
Scope
Scope: This document provides guidelines for insulation coordination of equipment with a rated voltage of AC 1,000 V to 2,000 V and DC 1,500 V to 3,000 V for some product standard technical committees. For equipment with a rated voltage not exceeding AC 1,000 V and DC 1,500 V, as well as insulation coordination equipment with higher or lower internal voltages, refer to the GB/T 16935 series. This document applies to equipment at altitudes not exceeding 2,000 m and provides guidance for use in high-altitude areas. This document specifies the safety requirements for electrical clearances, creepage distances, and solid insulation of equipment, including electrical testing methods for insulation coordination. Since functional insulation requirements do not fall under safety requirements, corresponding provisions are not included. This document does not address the determination of the following distances: — Insulation through liquids; — Insulation through gases other than air; — Insulation through compressed air.
