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 (cables and/or 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.

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 25A to 6,300A.

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.

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.

Trunking units without tap-off point are used for power transmission. These are available in standard lengths. Besides the standard lengths, the customer can also choose a specific length from various length ranges to suit individual constructive requirements.
