Abstract:
A cable and conduit system comprising:a cable having at least one internal conductor;a conduit; said conduit having an outer surface and an inner cavity; said cable received within said inner cavity of said conduit;a choke conductor; said choke conductor wound about said outer surface of said conduit in the shape of a spiral;a spiraled shield; said spiraled shield being wound about said outer surface of said conduit in a direction which is opposite to the direction in which said choke conductor is wound; said choke conductor and said spiraled shield each having first and second ends; said first end of said choke conductor connected to said first end of said spiraled shield, and said second end of said choke conductor connected to said second end of said spiraled shield;magnetic fields being formed by said choke conductor and said spiraled shield when current flows through said choke conductor and said spiraled shield due to a high voltage discharge near said cable; said magnetic fields being substantially cancelled, thereby reducing the damaging effects of the high voltage discharge.
