Images are inserted into some of the drawings.

Final qualification work of a student of secondary vocational education in the specialty Electrification and automation of agriculture.

At the beginning of the project  , overhead power lines with a self-supporting insulated wire (VLI) are considered to be a device designed to transmit electricity through insulated, twisted wires fixed to supports with fastening hooks, brackets and fittings to supports, racks of buildings, structures,  and  the main operational advantages. The project is considered on the example of the Southern Electric Networks. The section "Analysis of the economic activity of the enterprise" provides an economic analysis of the work of the electric grid enterprise, the service area of which includes this project.

       In the design and technical part, for an example of the calculation, a 10 kV line with an insulated wire with a total length of 21.5 km, which feeds fifteen TP-10 / 0.4 kV, is taken. The calculation of electrical loads is performed. For each section, the brand of power transformer was chosen, taking into account the increase in loads for the next 7 years. 

We calculated and selected a wire of the SIP brand 3-3x70. Performed the calculation of short-circuit currents and chose a fuse of the brand
