Abstract

MALLAS MAGNETICAS PROTECTORAS DE CONDUCCIONES ENTERRADAS. CONSISTE EN UNAS MALLAS DE MATERIA PLASTICA QUE EN SU FORMACION SE LES HA AÑADIDO POLVO FERRICO DE UNA GRANULOMETRIA NO SUPERIOR A 40U; ESTE POLVO SE MAGNETIZA POSTERIORMENTE SEGUN UN CODIGO PREESTABLECIDO SEGUN LA CONDUCCION ENTERADA QUE PROTEGE, ESTA MALLA SE DISPONE ALREDEDOR DE LA CONDUCCION DE FORMA QUE LA MAGNETIZACION PUEDE SER DETECTADA POR APARATOS SENSORES ADECUADOS. UNA VARIANTE CONSISTE EN APLICAR EL POLVO FERRICO DIRECTAMENTE EN LA FABRICACION DE CONDUCCIONES PLASTICAS.
