Electro Magnetic Fields (EMF) generated by high power cables and bus-bars are a growingconcern and a technical challenge to Consultants, Facility Managers and people in general,world-wide, in many facilities and buildings, due to new restricting EMF emission standardsthat limit continous exposure to people and machines due to health and performance issues.

AST shielding technology is the result of years of experience and over 500 successfulinstallations that have provided the know-how to standarize high-performance EMF shieldingproducts presented in this catalog.

Continuous exposure to Low Frequency Electro Magnetic Fields (EMF), caused by high powerelectric loads, as high power cables, alter the normal functioning of electronic equipmentand affects human beings health.

15% of electronic equipment failures (such as servers, electro-medical, PLCs... malfunction)or communication networks´ underperformance are reported to be caused by EMF .

EMF related problems are growing rapidly as per increasing power consumption in any buiding,creating more EMF sources and at the same time, affecting more people, as per space scarcetyand proximity to such loads.

EMF exposure is limited by various compulsory norms:

- Electronic equipment and Machinery: Limit of Magnetic Field exposure by norm IEC/EN 61000-4-8 is 3,75 uT(microTeslas) and is complusory to provide an environment with less than such level to ensure the secure and goodperformance of every-day-more-sensitive electronics and machinery. Norm IEC/EN 61000-4-3 establishes for sensitiveelectronics < 1 v/m limit exposure to high frequency EMF.

- Human Beings: limit of EMF continous exposure by NCRP to 1μT, must be observed to ensure people´s safety andavoid any health risk.

-U.V. Radiations: skin problems (reduction of Langerhans cells) and eyes.-Infrared Radiations: thermal effects-Radiofrequency (R.F.): thermal effects and bioelectric interferences, genetic transmission problems, nervous and heart system.

some relevant studies conducted to date:

-National Institute of Occupational Health (Magnetic Fields and Cancer: cellular study. Bo Holmberg): research on cancertumors and EMF exposure.

-Division of Biomedical and Behavioral Sciences, National Institute for Occupational Safety and Health (OSHA) (Cincinnati)(Magnetic Field exposition in skin cells, J. Snawder, R. Edwards): research on tumor and magnetic fields of 100 μT over a 14 day period.

-Electric Power Research Institute (Palo Alto) (Magnetic Fields and Animal Cells, J. Mc.Cann, R. Kavet, C. Rafferrty): researchon tumor and magnetic field.

Note: Although none of the studies conducted to date can absolutely correlate EMF and human health effects. AST stronglyrecommends to apply the ALARA (As Low As Reasonable Achievable) principle in accordance with NCRP recomendation.

2. Origin of EMF and Sources

Induced electron flow

Natural electron flow

EMF Effects on Electronic Equipment

1.- Electromigration:cause broken strips and communication problems.

3.- Antennae Effect:EMF Interference and some of the electrons are radiated,transforming the narrow strip in an antenna.

2.- Hot Electron Effect:induced transients, provoke logic errors and destroy transistors.

Passive shielding by flux shunting

MAGNETIC FIELD

ferromagnetic shield

AST Shielding Solution consists of a cost-effective hybrid shielding technology that by the combination of high-permeabilityand high conductivity materials produce a double effect of EMF absortion minimizing the residual magnetic field by an “eddycurrent” effect that pushes back the residual field back-in.

A smart design, that overlaps all cable tray segments minimizes any EMF leakage.

- Fully standardized products.- Special solutions upon request.- Provides secure environment for electronic equipment

and machinery and for people.- Certified EMF shielding performance according to IEC

standards.- Suited to any sort of building and applications: Office

buildings, Hospitals, Semiconductor plants,...- Complete turn-key solution from one single catalog

and source (trays, fasteners, supports,...)- Easy to install.- Suited to install in horizontal or vertical cable risers.- Shield-Tray provides convenient air-cooling to cables.

- Various models, sizes and Shielding performance suitedto different needs and applications.

- Maximum safety- Easy to select.- Shield-Tray segments overlapped to minimize EMF

leak by Belt technique.- Documented certification.- CE marked.- Earthing connection points.- Heavy duty construction.- Warranty 10 years.- Anti-rust treatment

“ 8.4.1.3 Option 3: An exposure guideline of 1 μT and 100 V/m: A considerable body of observations has documented bioeffectsof fields at these strengths across the gamut from isolated cells to animals, and in man. (...) . Most homes and occupationalenvironments are within these values, but it would be prudent to assume that higher levels may constitute a health risk

Installation method depends on wallmaterial.

If wall is made of brick or concrete,shielding panels will be fixed directlyto wall with screws.

In case of wall is made of gypsum wall,panels must be fixed with screws andspecial nuts.

4.Installation Guide

There are 3 different kind ofinstallations for shieldingtransformers:

- Wall protection (side)- Ceiling protection- Complete protection

(walls and ceiling)

Wall protection

Shielding will be applied on theside which radiates into theaffected area.

If wall is made of brick or concrete,panels will be fixed directly to wallwith screws.

NOTE: Panels must be connectedto ground with 25 mm2 copperwire.

In other cases, where transformerare fencedand shielded panelscannot be fixed it will be necessaryto install some steel structure atthe beginning, to attach shieldingpanels.

Structure consists in tubulargalvanized steel with squaresection (80 x 80). Separationbetween beams is 1000 mm, sameas width of pieces.

NOTE: structure must beconnected to ground with25 mm2 copper wire.

Ceiling protection

For ceiling installation, it will be necessary to mount somestructure in order to support all pieces.

The distance between ceiling and structure must be at least300 mm. and between transformer and structure at least 500mm. in order to ensure good ventilation.

Structure consists in tubular galvanized steel with squaresection (80 x 80). Separation between beams is aprox. 1000mm, same as width of pieces. See the picture beside.

The complete protection against magnetic fields in transformersconsists on shielding walls and ceiling.

In order to support all shield panels is necessary to mountthe appropiate steel structure.

The distance between ceiling and structure must be at least300 mm. and between transformer and structure at least 500mm. in order to ensure good ventilation. Distance betweenwall and structure must be at least 500 mm and betweenstructure and transformer must be at least 500 mm in orderto let free space for maintenance facilities.

The steel beams are separated 1000 mm. aprox.

Wall panels must be fixed to structure with 6 screws and 6nuts as minimum.

Ceiling panels must be fixed to structure with 4 screws and4 nuts as minimum.

“L” shielded panels sections must be placed on structure corners.

NOTE: structure must be connected to ground with 25 mm2

copper wire.

Shielding solutions to minimize electromagneticenvironmental levels and maximize protection forelectronic equipment and people.

Applications

Avoid degradation, malfunction and data losses in microelectronics:

· Antenna effect, “hot” electron effect, electromigration, ... cause more than 15 % of hardware failures.

· Protect equipment and people from hazardous EMF levels, always according to International normsEN 61000- 4-8, EN 61000-4-3, ICNIRP, NCRP...
