Medium-Voltage Equipment with New Dielectrics - EDIN



The EDIN project is an individual Ormazabal project carried out during 2016-2017.

Ormazabal's secondary distribution switchgear technology for medium-voltage is based on the use of the SF6 gas as an insulation and current breaking element. The ever-greater number of restrictions on the use of SF6 gas brings the need for a radical change in the technology used in Ormazabal products.


The main aim of the project is to make prototypes of feeder and fuse-protection functions with electrical values up to 24 kV - 630 A - 21 kA, using a gas insulating medium that does not have restrictions on the use of SF6 and has a GWP (Global Warming Potential) of less than 200.
