Trafo Shielding Plate 70mm

Our electro sheet is for use with toroidal trafos. It consists of two grain-oriented-steel layers that effects
The shielding sheet is placed around the toroidal transformer and the overlapping of the sheet is placed perfectly to the cable outbreak of the transformer. The shielding sheet can be fixed with a fixation tape, adhesive tape or rubber.
Commonly used to match highend stereo audio-gear that has different noise levels on left and right channel cause of trafo noise, hum. If the channel next to the toroidal trafo has a worser noise floor than the channel with greater distance to the trafo, this is an indicator for electro magnetic fields around the toroidaltransformer. In this case use the trafo shielding sheet, wrap it around your toroid-trafo to solve the electro magnetic radiation problem completely.

The effect of the electric shielding is not only cause the chemical composition, in particular its own special grain structure. In contrast to conventional steel, which consists of a chaotic arrangement of tiny crystals adhering to each other, the grains of the electro sheets are actually extremely large and also regarding orientation of their crystal axes aligned uniformly.
This equal grain orientation that matters, because the magnetisation of the material can be influenced.Cause its structure the material contracts to the de-magnetisation process very less resistance, in alternating 50 times a second, than conventional steels. Mu-metal has similar properties. This grain structure is achieved by a so-called thermo-mechanical treatment in the disturbed by a cold rolling process, the grain structure and a five to seven days a recrystallization heat treatment takes place.
