1 Scope

GB/T 28546-2026 is the Chinese national standard covering moving a hydro turbine and generator to site - components weighing hundreds of tonnes, shipped in pieces over months to a remote valley, with the preservation against corrosion, the packing against shock and the storage before erection. It replaces GB/T 28546-2012. It was issued on 28 January 2026 and has been in force since 1 August 2026, replacing GB/T 28546-2012. The document is under the responsibility of the China Electrical Equipment Industry Association. This page is published from the official record of the 2026 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 defines the terms and definitions for the packaging, transportation, and storage of components for large and medium-sized hydropower units, and establishes the standards for the handling of components for large and medium-sized hydropower units. The general principles for the packaging, transportation and storage of components stipulate the technical requirements for the packaging, transportation and storage of components for large and medium-sized hydropower units. This document applies to the packaging, transportation, handover and acceptance, and on-site storage of components for large and medium-sized hydropower units that meet one of the following conditions. The packaging, transportation, handover and acceptance, and on-site storage of the type hydropower unit shall be carried out in accordance with the relevant procedures.
