MAGNETIC AND ELECTRIC LOW FREQUENCY SHIELDING (50 Hz)


  

LOW FREQUENCY (DC-30 MHz) shieldeding enclosures are designed to protect individuals and equipment, against electric and magnetic low frequency fields radiation, originated from facilities such as electric transformer stations, power lines or railways.

In a shielding performed with our solutions based on Lámina de blindaje magnético MCL61, and Chapa de MU-METAL, get both the electric field (E) and magnetic field (B) low-frequency shielding .         

  

Magnetic field (H) is turned into the high permeability sheet. Maximum absorption capacity of the magnetic field is determined by magnetic flux saturation, which is usually set at 0.8 Tesla.                          

  

The ability to divert the magnetic field is given by the magnetic permeability (μ), which in turn varies depending on the magnetic field flux (B) exists.        

  

For higher magnetic permeabilities, we have two possibilities: increase the number of sheets (overlaying with intermediation of an insulating material) or using thicker sheets (increase the amount of high permeability alloy).

  

In  CEM-Ti sell "tiles" of a standard size of 30x30 cm. Available in two thicknesses. This product is intended for individual facilities, with little surface to be treated (for full installations of rooms or spaces ask for a quote or personalized advice).

  

For small shieldings (walls, electrical boxes, magnets, electronics ...) we recommend:

 

   

For full enclosures shield we recommend:

 

    

The panels must be installed without soldering, gluing them overlap between them, or by closing the joints with shielding sheet 0.1 mm thick.

   

We have BALDOSA MUMETAL MAGNOSHIELD DUR 0,5 MM  , of dimensions 0.33 x 0.33 meters. The installation method is to create a grid in front of the focus of the magnetic field, to the area in which the field is measured is less than 0.2 microTesla.

The "tiles" overlap, or close the joints with shielding sheet 0.1 mm thick.

  

We are importers and distributors of solutions YSHIELD and MU-METAL in Spain.

  

We install complete shielding and shielding enclosures.

HIGH FREQUENCY ELECTROMAGNETIC SHIELDING (700 MHz - 6 GHz) 


       

Currently, it would be advisable to install shieldings of HIGH FREQUENCY at all stays where we have high exposure times: bedroom, dining, office .. etc.

Such shieldings are normally done to protect people from exposure to strong high-frequency electromagnetic field, caused by sources close to mobile phone masts, wi-fi anteas municipal or domestic, and radar.

  

It is easy installation, involves the placement of different meshes, depending on the desired shielding capability, for thermal or acoustic insulation (between the partitions) when performing a newly built house.

 

Or, through plasterboard partition walls (flat system) in the reforms. In the floors is placed under the concrete layer and is fully integrated into the housing. O well, underneath a park when it comes to reform. These systems typically require grounding.

  

When no work is to be performed, have shielding in the form of paints, and curtains. To shield a bedroom (against mobile phone masts nearby), can be achieved with a solution of paint for walls and ceiling, curtain for windows if any.

   

METHOD FOR SHIELDING A STAY AGAINST HIGH FREQUENCY EMF FIELDS

  

The standard solution for shielding a bedroom or dining room, a home against electromagnetic radiation of high frequency EMF would be:

 Blindaje con Pintura HSF54 por instaldores de CEM-Ti

1) Paint the walls with Pintura de Blindaje HSF54 . You must create a perimeter around the wall (5-10 cm from the edge) with Cinta Conductora EB1. The perimeter is connected to tape Kit de Toma de Tierra GW . It can also replace the conductive tape, using the Aditivo Electroconductor AF3, which mixes with the paint.The paint finish is black. Shielding paint requires 12-24 hours of drying. After this time, we must end the desired paint color.

  

2) The windows or doors are protected by Shield NATURELL curtains. Optionally have Dressmaking service, getting ready to hang the curtain.  

    

With this method, can reduce initial levels of 2 miliWatts/m2 environment (2000 microWatts/m2) by a factor of 10-12, and finally lowering them to 0.2 - 0.1 miliWatts/m2. (200 -100 microWatts/m2).
