Estas capas son usadas como contactos interno y externo con el polietileno reticulado (XLPE) en cables de media tensión formando interfaces donde se acumula la carga. Si se usan capas semiconductoras de la misma composición química se atenúan los paquetes de carga y se retrasa el tiempo de propagación de los mismos a través del volumen de las muestras de LDPE.]]></p></abstract>

These layers are used as internal and external contacts with cross-linked polyethylene (XLPE) MV cables forming interfaces where charge accumulates. Same chemical composition are used, the ion charge packets is attenuated and delay the propagation time through the sample volume of LDPE.]]></p></abstract>
