Our high voltage connectors are also present in the IFA2 project. A 1000 MW HVDC (high voltage direct current) electrical interconnector currently under construction, between the British and French transmission systems. It will be the second link to France that National Grid has developed with RTE.

The grid connection point in France is located at the Tourbe 400kV substation in Normandy. In UK the grid connection point is a National Grid substation in Chilling Lane. Which, is connected to the conversion station in Daedalus via subway cables.

SBI Connectors is participating in this project by providing customized High Voltage connectors for Tourbe and Daedalus HVDC station converters.

The connectors have been designed and validated through electrostatic finite element simulations (corona simulations). This type of simulations is a very important tool for our R&D department since it allows to highlight critical points on the connectors and to foresee if, once installed, they could have corona issues. For this reason, corona simulations are increasingly used as a standard procedure in the development and validation of new products and in providing solutions to existing corona issues.

And with IFA2 we have expanded the list of HVDC projects where SBI has supplied its connectors in different countries worldwide, further strengthening our experience in designing and manufacturing high voltage connectors for substations.
