Description

Trafo shield for toroidal trafos: 35cm x 4cm

Our electro sheet is for use with toroidal trafos. It consists of two grain-oriented-steel layers that effects

double shielding around the toroid and 6-times shielding on the overlapping to eleminate horizontal radiation hum and noise of toroidal trafos.

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.

Specs:

  • Size: 35cm x 4cm

 

Material:

  • two layer "grain-oriented steel with 3% silizium" - "DIN46400"

 

Application:

  • trafo shielding

 

For more information (google translated - Please read the german description for original):

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.

How to install our sheets:
The trafo shielding sheet can be wrapped around the toroidal trafo. Fix it with a tape and take the overlapping part to the outgoing wires as descripted in the following PDF file. Fix it with a tape. For a detailled instruction take a look into the PDF.

"My first dual g-pultec. The trafo shielding sheet improved the noise-floor to more than -94db. It is easy to install."

    Excellent Product
    Installed around my 90mm diameter Torroid transformer in my electronic crossover. Measured 80% reduction in EMF from both the top and sides. Should do the job.
    Tried on another amp with more modest results because wires got in the way of slipping it on more that 75%. Probably would work if I had cut a recess to make better fit. Will order another one and give that a try :-)

    Great product
    I shielded my old Trace Elliot GP12SMX transformer with it and the hum that was bugging me for ages is now gone.

    Trafo Shielding Sheet XL
    Effective to shield out the magnetic field around the transformer.
