Summary
Learner is master of used materials by production of electrical machines and production processes electrical machines.
Subject engage in constructional, electrical isolative materials, materials for winding production, winding production, production of cage rotor, production of commutator and impregnation, of winding electrical machines, with balancing of electrical machines and production of commutator. Tutorial is complemented with excursion into choice works in inland eventually with video projection.
An aim of this course is to acquire basic principles of production technology of the controlling and switching devices up to technological complexes such as very high voltage switching stations. The main parts of this course deals with construction materials and technological operations including surface treatments, insulating materials technologies, epoxides, contacts and current carrying gates up to protective covering techniques and treatments for instrument meteorological conditions. A number of excursion to manufacturers of these devices (such as ABB , OEZ, MEP is added to this course.
