1 Scope

GB/T 46785-2025 is the Chinese national standard covering the turbine built for the desert - the sand that erodes a blade leading edge and works into every seal and filter, the temperature range from below freezing to fifty degrees, the low humidity and static, and the water that is not available for cleaning. China is building its largest wind and solar bases in exactly this terrain. First edition. It was issued on 2 December 2025 and has been in force since 2 December 2025, as a first edition. The document is under the responsibility of the China Machinery Industry Federation. This page is published from the official record of the 2025 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the environmental conditions, technical requirements, and testing procedures for wind turbine generator sets (hereinafter referred to as "generator sets") in desert, Gobi, and arid regions. Inspection methods, inspection rules, and requirements for the unit in terms of transportation, installation, operation and maintenance. This document applies to the design of grid-connected horizontal axis wind turbine generators used in desert, Gobi and arid regions.
