Why I prefer busbar trunking systems more than cables. Planning concept for power supply When a planning concept for power supply is developed, it is not only imperative to observe standards and regulations, it is also important to discuss and clarify economic and technical interrelations cables andor busbar trunking systems depending on situations. The rating and selection of electric equipment, such as distribution boards and transformers, must be performed in such a way that an optimum result for the power system as a whole is kept in mind rather than focusing on individual components. The most important is that all components must be sufficiently rated to withstand normal operating conditions as well as fault conditions. Further important aspects to be considered for the creation of an energy concept are Type, use and shape of the building e. Load centers and possible power transmission routes and locations for transformers and main distribution boards.

Several options must be assessed in terms of their technical and economic impacts. Busbar Design Calculation Pdf' title='Busbar Design Calculation Pdf' />The following requirements are the main points of interest Easy and transparent planning. Long service life. High availability. Low fire load. Flexible adaptation to changes in the building. Most applications suggest the use of suitable busbar trunking systems to meet these requirements. For this reason, engineering companies increasingly prefer busbar trunking to cable installation for power transmission and distribution. The most common busbar trunking systems ratings are from 2. A to 6,3. 00 A. Planning Notes. Considering the complexity of modern building projects, transparency and flexibility of power distribution are indispensable requirements. In industry, the focus is on continuous supply of energy as an essential prerequisite for multi shift production. Busbar trunking systems meet all these requirements on efficient power distribution by being easily planned, quickly installed and providing a high degree of flexibility and safety. The five main advantages of busbar trunking systems are Straightforward network configuration. Low space requirements. Easy retrofitting in case of changes of locations and consumer loads. High short circuit strength and low fire load. Increased planning security. Power transmission. Power from the transformer to the low voltage switchgear is transmitted by suitable components in the busbar trunking system. These components are installed between transformer and main distribution board, then branching to sub distribution systems. View and Download Emerson Affinity user manual online.

Besides the standard lengths, the customer can also choose a specific length from various length ranges to suit individual constructive requirements.

Power distribution is the main area of application for busbar trunking systems. This means that electricity cannot just be tapped from a permanently fixed point as with a cable installation. Tapping points can be varied and changed as desired within the entire power distribution system. In order to tap electricity, you just have plug a tap off unit on the busbar at the tap off point. This way a variable distribution system is created for linear and or area wide, distributed power supply. Busbar tap off Sivacon 8. PSTap off points are provided on either or just one side on the straight trunking units. For each busbar trunking system, a wide range of tap off units is available for the connection of equipment and electricity supply. Guitarport Tones Download. Table 1  Cable Busbar comparison.

Easy to plan, quick to install and flexible to use. Busbar trunking systems bring energy economically into any building. The power distribution system can be precisely planned from the total load rating and the type and number of loads. Clarity is assured by the line shaped network topology with regularly arranged load tap offs. Using standardized sizes, all applications can be implemented quickly and in minimum space. Quicker when it comes to installing. Benefits during installation. Two man assembly of busbar trunking systems saves time and money compared to the costly cable installation method. Installation errors are practically ruled out by the safe and user guided connection technology. No special tools are required. SIVACON 8.
