Gmont Cable Brno
Rampáčková, Monika ; Suchánek,, Petr (referee) ; Nový, Alois (advisor) ; Brzoň, Roman (advisor)
The content of the bachelor thesis was elaborated follow-up levels of project documentation for studying the new building Gmont cable in Brno, which I designed for subject AG032. The proposed building is located in the city of Brno - Cernovice. Building is near by many types of services, especially industrial factories. The building is mostly one – storey or two – storey. Newly built plant of Gmont s.r.o. will be one-storey, focused on the manufacture of cables and the assembly of cable harnesses, cables and wires. There is an administrative part in the building providing the organization of the company. The main idea was to fit the object appropriately into the surrounding environment using a minimalist style. Compositionally mass consist of 3 volumes, which together form the final shape of the building and diagonally follow adjacent communications. Atrium is inserted into the center of the building. An important element that gave the construction a characteristic expression was the use without a maintenance facade. The direct light coming into the building is scattered through perforated sheet metal, creating an interesting game of light and shade in the interiors. In the main production, light is brought to the object by saw blades oriented northwards. The construction technical site is designed with prefabricated reinforced concrete prefabricated structural skeletal system and the dry construction process prevails.

Harness tester
Smola, Tomáš ; Bohrn, Marek (referee) ; Pavlík, Michal (advisor)
This thesis deals with issue and construction of wire harness tester. In the first place, is this thesis focused on market exploration and comparison of comercial testers with concrete requirements for small batch production. I will try to find a suitable product in worldwide market, which would be convenient for company producing construction machinery. For testing switchboard harness we need to test interconnections between connectors, resistors, relays, diodes, transils and switches in the dashboard. If I can not find some product, I will try to design some new tester. My priorities will be testing all components in harness, maximum flexibility of tester for the future trends in contruction of rollers and user friendly control.

G-mont Cable Brno
Jussupov, Daniyar ; Suchánek,, Petr (referee) ; Nový, Alois (advisor) ; Čupr, Karel (advisor)
The aim of the bachelor thesis was the creation of individual stages of the project documentation - Documentation for Building Permits and Documentation for building construction based on the study, elaborated in subject AG35. The subject of the bachelor's thesis is a new building of the G-mont Cable plant for cable production on the street Těžební, in the Brno-Černovice district. The building's inspiration is typically a black-color cable that has been assembled with a cable of different colors: red, blue, green, yellow. The building is divided into three units -production, administration and social facilities, but the building looks like a whole. For the facade, the black color sheet ks1000 is used. Throughout the construction there are colored lines, in the production part are windows, in the administrative part only plastic glass on the facade. The building has a dynamic shape with sloping lines on the facades. In the administrative part there is a large roof skylight. The light coming into the main production penetrates through the saw blades facing north. Scattered light is not aggressive and does not interfere in any time of day.

Analysis of Using Cable Sections in the Route of 400 kV Overhead Line
Belatka, Martin ; Rusek, Stanislav (referee) ; Modlitba, Petr (referee) ; Matoušek, Antonín (advisor)
The thesis deals with the use of cable sections in the overhead transmission route of the 400 kV transmission system in the Czech Republic, with the design of the arrangement of the cable route and with the solution of the crossover of the cable line with other networks of the technical infrastructure or natural obstacles. The thesis shows what the construction of a 400 kV cable line in the overhead transmission route - which has not been implemented in the Czech Republic as of yet - entails in practice. The first, general part deals with the electrical properties of both the cable lines and the combined overhead transmission lines with intermediate cable sections, and this sets out limitations on the maximum possible length of the cable sections. The following chapters provide an analysis of the magnetic field of the cable line, its impact on the surrounding environment and the possibilities of its shielding. On the basis of this knowledge optimization of the designed cable route arrangement is carried out in order to make the route comply with hygiene limits. The next part uses selected locations on a real route of overhead 400 kV transmission line to show what the construction of cable sections inserted into the route of overhead 400 kV line would involve. The design includes a professional estimate of the time and financial demands of the construction.
