Holland Shielding Systems B.V. hat ein neues Material für die Abschirmung von NiederfrequenzMagnetfeld entwickelt. Diese Felder werden durch Installationen, in denen hohe Strom fließen, z.B. Transformatorräume, Stromleitungen, Hauptleitungsträgersysteme und nahe gelegene Hochspannungskabel erzeugt.
Die Frequenz dieser Magnetfelder ist gewöhnlich 50/60 Hz.
Aber das MuFerro Material ist für die magnetische Abschirmung in Frequenzbereich von 10 Hz zu 100 kHz verwendbar.
MuFerro kombiniert die durchlässige und Übersâttigungeigenschaften, die es extrem verwendbar für niedrig-häufige Magnetfelder der Siebung bildet.
Magnetic fields pose a serious threat to human health and wellbeing. Scientific research has shown that exposure to magnetic fields of > 300nT or 0,003 Gauss increases one's chance of developing leukemia significantly.Moreover there are numerous other health symptoms that are associated with exposure to magnetic fields, e.g. headaches, depression, and insomnia. For this reason the ICNIRP (International Commission on Non-Ionizing Radiation Protection)has made the recommendation that for working spaces exposure should be < 0.5 μT=500 nT and for public spaces it should be < 0.1 μT=100nT.
Abgesehen von ihrer negativen Auswirkung auf Gesundheit, können starke Magnetfelder Elektronik in den direkten Umlagerungen des Feldes stören oder schädigen. Zusätzlich stören Magnetfelder empfindliche Maße in den Krankenhäusern und in den Labors.
Holland Shielding Systems B.V. can realise magnetic shielding even after the transformer has been placed. For screening whole buildings, or rooms, the shielding material is applied to walls, ceilings and/or floors. This protects both people and electronics.
Before the screening/shielding is put in place a site survey (magnetic field-strenght measurement) can be conducted. We not only measure the magnetic field strength but also locate its probable source. The measurement results are provided in a report.
Due to space restrictions, one of our customers was forced to create a workplace in a room which had formerly been used as a warehouse and that was located above power transformers. After the magnetic fields were noticed by flickering computer displays, we were asked to carry out a magnetic field measurement. It was found that the magnetic field-strenght was far above the standard referred to above: it was 750nTesla. The magnetic field was reduced by installing an umbrella construction of MuFerro™ 6800. After completion of this project, the magnetic field measured only 80nTesla.
The graph below show the magnetic fields in nano Tesla or 10-5 Gauss before and after the magnetic shielding was installed.
Several clients have engaged us to place MuFerro™ 6800 shielding, including:
