Electromagnetic field shielding electric heating pad

摘要: An electrical heating pad for use with an ungrounded source voltage comprises a element arranged in the and defining substantially coplanar plane fabric outer cover co-planarly enclosing element. The includes first core made of insulating material; conductive wound around using as axis; second material surrounding relation to element; axis. elements are connected each other at one ends least partially cancel out magnetic field generated from There is shield layer located side defined by shielding electric field. In pad, preferably generates more heat than that regard, has lower total resistance
