Guidance for installation procedures and tolerances of hydroelectric machines - Part 5: Bulb turbines and generators
The purpose of this guide is to establish, in a general way, suitable procedures and tolerances for the installation of bulb turbine and generator. This guide presents a typical assembly and whenever the words "turbine" and "generator" are used in this part, it refers to bulb turbine and generator. There are many possible ways to assemble a unit. The size of the machine, the design of the machine, the layout of the powerhouse, the sequence of concreting or the delivery schedule of the components are some of the elements that could result in additional steps, or the elimination of some steps and/or assembly sequences. It is understood that a publication of this type will be binding only if, and to the extent that, both contracting parties have agreed upon it. The guide excludes matters of purely commercial interest, except those inextricably bound up with the conduct of installation. It also excluded to specifications of the civil works but this aspect of the work should be taken into consideration during the assembly of the units. Wherever the guide specifies that documents, drawings or information is supplied by a manufacturer (or by manufacturers), each individual manufacturer will furnish the appropriate information for their own supply only.

Lignes directrices des procédures et tolérances d’installation des machines hydroélectriques - 5: Turbines et alternateurs de type bulbe
IEC 63132-5:2023 doit établir, de manière générale, des procédures et des tolérances appropriées pour l’installation de turbines et de générateurs hydroélectriques. Ce guide présente un assemblage typique. Il faut reconnaître qu’il existe de nombreuses façons possibles d’assembler une unité. La taille des machines, la conception des machines, la disposition de la centrale et le calendrier de livraison des composants sont quelques-uns des éléments qui pourraient entraîner des étapes supplémentaires, l’élimination de certaines étapes et / ou des séquences d’assemblage.
Navodila za postopke vgradnje in tolerance hidroelektričnih strojev - 5. del: Cevne (Kaplanove) turbine in generatorji (IEC 63132-5:2023)
Namen teh navodil je na splošno vzpostaviti ustrezne postopke in dovoljene tolerance za vgradnjo cevnih (Kaplanovih) turbin in generatorjev. V navodilih je predstavljen tipični sestav, izraza »turbina« in »generator« pa se povsod navezujeta na cevno (Kaplanovo) turbino in generator. Enoto je mogoče sestaviti na več načinov. Velikost in zasnova stroja, postavitev elektrarne, zaporedje betoniranja ter razpored dobave komponent so nekateri od elementov, ki lahko zahtevajo dodatne korake ali odpravo nekaterih postopkov in/ali korakov sestavljanja.
Publikacija te vrste je zavezujoča le, če in v obsegu, v katerem jo potrdita obe pogodbenici.
Navodila ne zajemajo izključno komercialnih interesov, razen tiste, ki so neločljivo povezani z izvajanjem vgradnje. Prav tako niso zajete specifikacije gradbenih del, vendar je priporočljivo ta vidik del upoštevati pri sestavljanju enot.
Če je v navodilih navedeno, da dokumente, skice ali informacije zagotovi proizvajalec (ali proizvajalci), bo vsak posamezni proizvajalec predložil samo ustrezne informacije za lastno dobavo.
