1. An electromagnetic shielded sleeve comprising a spacer fabric having an upper surface and a lower surface formed in such a way as to define at least one longitudinal channel configured to enclose and carry a cable, wherein the spacer fabric is integrally formed and comprises: a first textile layer having a first width and forming the upper surface of the spacer fabric;a second textile layer having a second width and forming the lower surface of the spacer fabric, wherein the second textile is arranged in opposing back-to-back relation and spaced apart from the first textile;a plurality of connecting yarns interwoven with the first textile layer and the second textile layer connecting the first textile layer and the second textile layer to one another, wherein the plurality of connecting yarns is spaced at a first regular interval along the first width of the first textile layer and the second width of the second textile layer thereby providing adjacent sets of connecting yarns; and,an electromagnetic shielding material comprising a plurality of conductive yarns, wherein the conductive yarns are located between the first textile layer and the second textile layer, wherein the plurality of conductive yarns is spaced at a second regular interval along the first width of the first textile layer and the second width of the second textile layer and each conductive yarn is located between two adjacent connecting yarns, wherein the conductive yarns are not interwoven with the first textile, the second textile, or the connecting yarns, andwherein the spacer fabric does not contain any electromagnetic shielding material on an upper or lower surface of the spacer fabric. 2. The electromagnetic shielded sleeve of claim 1, wherein the distance between the upper surface and the lower surface of the spacer fabric is between about 3 millimeters and about 20 millimeters. 3. The electromagnetic shielded sleeve of claim 1, wherein the first textile layer and the second textile layer are woven. 4. The electromagnetic shielded sleeve of claim 1, wherein the first textile layer and the second textile layer are knit. 5. The electromagnetic shielded sleeve of claim 1, wherein the first textile layer forming the upper surface of the spacer fabric and the second textile layer forming the lower surface of the spacer fabric have a coefficient of friction of between about 0.06 and 0.14. 6. The electromagnetic shielded sleeve of claim 1, wherein the conductive yarns are selected from the group consisting of metallic wires, yarns coated with metals, and mixtures thereof. 7. An electromagnetic shielded conduit comprising a conduit and an electromagnetic shielded sleeve within the conduit, wherein the electromagnetic shielded sleeve comprises a spacer fabric having an upper surface and a lower surface formed in such a way as to define at least one longitudinal channel configured to enclose and carry a cable, wherein the spacer fabric is integrally formed and comprises: a first textile layer having a first width and forming the upper surface of the spacer fabric;a second textile layer having a second width and forming the lower surface of the spacer fabric, wherein the second textile is arranged in opposing back-to-back relation and spaced apart from the first textile;a plurality of connecting yarns interwoven with the first textile layer and the second textile layer connecting the first textile layer and the second textile layer to one another, wherein the plurality of connecting yarns is spaced at a first regular interval along the first width of the first textile layer and the second width of the second textile layer thereby providing adjacent sets of connecting yarns; and,an electromagnetic shielding material comprising a plurality of conductive yarns, wherein the conductive yarns are located between the first textile layer and the second textile layer, wherein the plurality of conductive yarns is spaced at a second regular interval along the first width of the first textile layer and the second width of the second textile layer and each conductive yarn is located between two adjacent connecting yarns, wherein the conductive yarns are not interwoven with the first textile, the second textile, or the connecting yarns, andwherein the spacer fabric does not contain any electromagnetic shielding material on an upper or lower surface of the spacer fabric. 8. The electromagnetic shielded conduit of claim 7, wherein the distance between the upper surface and the lower surface of the spacer fabric is between about 3 millimeters and about 20 millimeters. 9. The electromagnetic shielded conduit of claim 7, wherein the first textile layer and the second textile layer are woven. 10.
