Pre-wired to the wastewater treatment plant
\nA complicated installation between pumping stations and agitators is too time-consuming, cost-intensive and also disrupts the work on site. For this reason, the international electrical engineering general planner wanted the most convenient solution possible for preparing the control system for a sewage treatment plant (5 soccer fields in size) in Bahrain, Arabia.<\/p>\n
The switch specialists from Kraus & Naimer had it. Developed according to a whole list of customer specifications, they assembled the ready-to-use mini switch cabinets directly in Karlsruhe, which can now be fully integrated into the sewage treatment plant. Main switches in 8 power ratings, different cable cross-sections and combinations of operating elements – countless different variants were built and pre-wired according to a precise plan.<\/p>\n
Ready-made, but expandable
\nOne of the requirements was: only one cable for the main and control circuits. For this reason, multicore cables were used. Instead of 2 or 3 cables, only one cable needs to be routed out of the mini control cabinet.<\/p>\n
Nevertheless, it should be possible to add additional sensor cables. For this reason, additional free terminal blocks were fitted inside the enclosures, which can be connected on site if required.<\/p>\n
Protecting the devices against external influences such as vapors or shocks …<\/p>\n
… was also an issue. That’s why the choice fell on robust polyester enclosures with similar mechanical properties to metal. They are robust and weather-resistant and reliably protect the inner workings.<\/p>\n
Together with additional main switches and emergency stop buttons in the enclosure, 160 fully assembled parts left the Karlsruhe plant on time for Bahrain.<\/p>\n
