esquemas desarrollados

Because "desarrollado" does not mean that. And "esquemas desarrollados" (schematics prepared) may seem redundant to you, but this kind of Spanish construction is commonly used (e.g. pagos realizados, días trabajados, etc.). In any event, IMO opinion there's actually no difference between "esquemas" and "esquemas desarrollados". They're referring to the same schematics.

Why not? It could do. Obsviously it's not an equivalent but could be a relevant contextual translation.
esquemas = schematics
esquemas desarrollados = the same schematic (or part thereof) blown up to a larger scale.

"desarrollado" has nothing to do with the scale.

Is there a difference in scale? It might just mean "blown-up/large scale schematic"

Thanks Charles. Yes, I understand it is widely used, and I have used schematic in other documents. The problem is the apparent contrast between esquema and esquema desarrollado. I will probably go with detailed schematic, although they all seem to be pretty detailed.

It may not be clear to you from Phil's answer that "esquema desarrollado" is a standard term for a certain type of electrical circuit diagram in Spanish, as a Google search will show. It's not altogether easy to decide what to call it in English, since some sources treat "esquemático" and "desarrollado" as different types of diagram. However, from descriptions of "esquemas desarrollados" I think it's simply a more detailed schematic diagram, and I don't think we have another special term for it in English.
