Flexible double electrical shielding jacket

An electrical shielding jacket comprising:

• a flexible elongated PVC casing having inner and outer surfaces, two edges and two ends;
• an outer elongated electrical shield adjacent the casing and having two edges and two ends, which shield comprises a 100 mesh copper strip having two edges and two ends wherein the strip edges are folded back onto the shield to form the shield edges and are adjacent the inner surface of the casing and the ends of the outer shield extend beyond the ends of the casing;
• an inner elongated electrical shield adjacent the outer shield and having two edges and two ends, comprising a strip of flexible polyethylene terephthalate film having inner and outer surfaces, two edges and two ends, and a layer of aluminum on the inner surface of the strip of film, wherein the outer surface of the strip of film is positioned adjacent to the outer shield;
• a wire braid extending longitudinally along the layer of aluminum;
• and
• a zipper for joining the two casing edges for forming a tube.

A flexible, closeable electrical shielding jacket comprising:

• a flexible elongated casing having inner and outer surfaces, two edges and two ends;
• an outer elongated electrically conductive shield adjacent the inner surface of the casing and having two edges and two ends;
• an inner elongated electrically conductive shield adjacent the first shield and having two edges and two ends;
• and
• casing closing means extending along each casing edge for joining the two casing edges for forming a tube;
• wherein the inner shield and outer shield are electrically insulated from each other.
