Gamma takes care of every detail of the insulation of motors (DC / LV / MV / HV, HV, traction) and generators, finding the optimal solutions for each case.
All this thanks to the internal Insulating Laboratory and the collaboration with leading companies – such as Isovolta AG, Gebauer & Griller Gmbh, Relats Sa – of which Gamma converts and distributes products.
GAMMA Insulating Laboratory
In the Gamma Insulating Materials Laboratory are performed the following tests on materials:
- Analysis of composition
