Name of the case: OTDC switch disconnector ”Sunday”
Description:
ABB Oy brought DC switching to a whole new level with their OTDC ”Sunday” range. Not only improving the operational voltage from 1000Vdc to 1500Vdc but also minimizing the footprint and improving the arc extinguishing behavior for DC switching. Through optimized design, raw material savings for the production of the switch, compared to its predecessor and competitor products are realized. Also savings in system components are achieved by using OTDC ”Sunday”. Stepping up the operating voltage to 1500Vdc allows the usage of smaller cables and conduits which decreases the amount of materials applied, and so costs by up to 40% for system manufacturers.
By lowering the amount of resources used, this product is directly contributing to sustainability and making energy distribution greener.
