- Additional insulation: in case of failure of the main insulation, discharge of the defect to the ground without communication with the secondary.
- Static interference attenuation: In the case of a computer power supply, it releases part of the static interference of the network to the ground.
The impregnation under pressure and vacuum allows a complete and deep application of the protective varnish for the transformer. This process is more efficient than simple soaking but remains much longer and more expensive. This process allows a better mechanical hold of the varnish and further improves the durability of the transformer.
The anti-vibration pads absorb any vibrations produced by the magnetic circuit.
