ASIN: B00200LOYE "Electrical Drawing" is divided into four chapters: firstly, the basic knowledge of electrical drawing is introduced, and then the method of drawing electrical circuit diagram and building electrical installation diagram with manual ruler is described. The fourth chapter explains the knowledge of computer drawing. The rapid development of economy, science and technology and the continuous progress of society in China put forward higher requirements for the professional knowledge and professional quality of electrical technicians. Electrical drawing is written to meet the needs of social development and professional talents. The specialty of electrical drawing is comprehensive, systematic in knowledge, practical in application and epochal in content. According to the principles of practicality, novelty, conciseness, being close to reality and applying what one has learned, this paper systematically expounds electrical drawing from basic knowledge to drawing skills, from manual ruler drawing to computer drawing, and from electrical circuit diagram to building electrical drawing. At the end of the book, there are common materials for electrical drawing and drawing identification.

The latest national drawing technical standards and specifications have been implemented and applied in the compilation of electrical drawings.

Teachers who use electrical drawing as teaching materials will get electronic teaching plans as reference. The teaching plan towel provides the teaching outline of electrical drawing course module (reference), the teaching outline of cAD drawing special week (reference), the two-color part of chapter 2 and chapter 3 (convenient for teaching), as well as the case color circuit diagram and color plane layout. If necessary, you can fill in the teacher information feedback form to obtain it. order
