SIVACON 8PS TRUNKING SYSTEMS
LI system
Transmission of high currents with low voltage drop thanks to the sandwich design
data transmission with powerline technology
Reliable in operation
The LI system is particularly suited for applications from 800 A to 6,300 A in which large amounts of power have to be flexibly transmitted over long distances, in infra- structure – for example, in multi-floor buildings – as well as in industrial applica- tions. Thanks to the sandwich design, the system allows power transmission with a low voltage drop. The LI system can run at full load at high temperatures1) without derating.
Safe for personnel and equipment
The LI system offers a large range of design verified trunking and tap-off units in accordance with the latest standards IEC 61439-1/-6, enabling a high level of safety for personnel and equipment. Fur- thermore, the fire barrier of the LI system has been tested for fire resistance classes EI 90 and EI 120 in accordance with
EN 1366-3 to meet European Standard building requirements.
Numerous usage options due to high short-circuit rating
Power distribution can be reliably and simply planned thanks to the design verified connection to SIVACON S8 switchboards and safe connection to transformers. The high short-circuit rating and compact design open up many fields of application. In the ventilated system (IP34), the epoxy coating of the conductors offers additional protection against water (sprinkler-suitable).
Integrated and future-proof
Innovative technical features such as tap-off units with communication-capable measur- ing and switching devices enable modern energy management in accordance with ISO 50001 – meeting the latest demands for increased energy efficiency. Thanks to the powerline technology of the LI system, power and data are transmitted cost-effi- ciently via the current conductors.
