Busbar instead of cables
When you choose the LI busbar trunking system, you're opting for a secure, future-proof investment. This is because you're banking on an integrated solution for safe and reliable power supply that is highly flexible and efficient across the board – from planning and installation to operation. This reliable system is particularly well-suited for applications in the 800 A to 6,300 A range that have to reliably transmit large volumes of power over long distances – such as in infrastructures, multi-storey buildings and industrial installations.
Thanks to its compact sandwich design, the LI system allows efficient and modern power management with a low voltage drop. It can be operated up to full load at high temperatures without derating.
The system's future-proof functionalities and innovative technical features such as versatile tap-off units with communication-capable measuring and switching devices are not its only persuasive highlights: Its safety standards are also impressive. A broad selection of design verified trunking and tap-off units compliant, with Parts 1 and 6 of the IEC 61439-series international standards ensure a high level of personal and equipment safety as well as enhanced operational availability. What’s more, the system meets the Class EI90 and EI120 fire protection requirements, tested to EN 1366 Part 3 European building regulations.
The LI busbar trunking system empowers you to build a cost-efficient infrastructure. Its compact sandwich design enables the system to be easily integrated into narrowly confined building structures. A range of conductor configurations and modular tap-off units equipped with circuit-breakers and fuse switch disconnectors or with various junction units make it simple to flexibly design and adjust your power supply system at any time.
In addition, tap-off units for up to 1,250 A that can be connected while lines are live enable simple changes or adjustments to be made during operation*. This can prove useful, for example, when live production lines require new tap-off units for machinery or work stations.
* according with EN 50110-1 (VDE 0105-1); please always observe national regulations/standards
