To make this a "proper text," the wording depends on what you are trying to describe. Here are three ways to refine it based on common professional contexts: 1. Technical Title or Heading If you are labeling a document or a section of a manual:
This section contains electrical diagrams specifying all necessary component dimensions. 3. Standards-Compliant (GOST style) shemy jelektricheskie razmery
The phrase (transliterated from Russian схемы электрические размеры ) translates to "electrical diagrams: dimensions."
