SIVACON 8PS TRUNKING SYSTEMS
LD system
data transmission with powerline technology
Made in Germany, the LD system has been in operation worldwide for more than 50 years, offering maximum reliability and user friendliness thanks to systematic further development.
Reliable power transmission for high power requirements
The LD system, easy and fast to install, covers the current range from 1,100 A
to 5,000 A. It transmits and distributes the power between the transformer, main power distribution board and sub-distribu- tion boards on production sites with high power requirements, for example, for welding lines in the automotive industry.
More safety at long distances
An internal PE conductor increases the cross-section of the protective conductor and ensures a low impedance in the event of faults. It facilitates longer busbar runs as well as an assured response of the switching device, also for long current paths. In addition, tap-off units with circuit break- ers up to 1,250 A increase the availability of the power distribution.
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).
Future-proof solution
Energy data can be recorded with communica- tion-capable measuring and switching devices via tap-off units. Thanks to powerline technology, power and data are transmitted cost-efficiently via the current conductors. This enables a modern energy management in accordance with ISO 50001 – meeting
the latest demands for increased energy transparency.
