Abstract
Abstract A conductor for high voltage of electricity, comprising a plurality of circular conductor wires which are wound helically to form a circular cable and a protrusion wire which is helically wound with the conductor wires as part of the cable in the outer periphery of the cable, so as to protrude beyond the outer periphery of the cable.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
Conductor for high voltage electricity comprising: (a) a plurality of circular conductor wires which are wound helically to form a gernerally circular cable, said cable including an outermost annular layer, and (b) a protrusion wire which forms part of said outermost annular layer and which extends helically along said cable with the wires of said outermost layer, a portion of, said protrusion wire protruding outwardly beyond the outer periphery of said cable, said protrusion wire being elongated in cross-section and having a major dimension which extends along a radial line which extends from the center of said cable and a minor dimension which is substantially equal to the diameter of said conductor wires, the dimension of said protrusion wire in a direction which is normal to said radial line being no greater that said minor dimension at any point along said radial line.
Claim 2
Dependent Claim
143 words
Conductor for high voltage electricity comprising: (a) a plurality of circular conductor wires which are wound helically to form a gernerally circular cable, said cable including an outermost annular layer, and (b) a protrusion wire which forms part of said outermost annular layer and which extends helically along said cable with the wires of said outermost layer, a portion of, said protrusion wire protruding outwardly beyond the outer periphery of said cable, said protrusion wire being elongated in cross-section and having a major dimension which extends along a radial line which extends from the center of said cable and a minor dimension which is substantially equal to the diameter of said conductor wires, the dimension of said protrusion wire in a direction which is normal to said radial line being no greater that said minor dimension at any point along said radial line.
Claim 3
Dependent Claim
18 words
Conductor as recited in claim 1, wherein said protrusion wire is made entirely of an electrically conductive material.
Claim 4
Dependent Claim
80 words
Conductor for high voltage electricity comprising: (a) a plurality of circular conductor wires which are wound helically to form a generally circular cable, said cable including an outermost annular layer, and (b) a protrusion strand which forms part of said outermost annular layer and which extends helically along said cable, said protrusion strand protruding outwardly beyond the outer periphery of said cable, said protrusion strand being made entirely of a material having a low dielectric constant and high electrical resistence.
Claim 5
Dependent Claim
80 words
Conductor for high voltage electricity comprising: (a) a plurality of circular conductor wires which are wound helically to form a generally circular cable, said cable including an outermost annular layer, and (b) a protrusion strand which forms part of said outermost annular layer and which extends helically along said cable, said protrusion strand protruding outwardly beyond the outer periphery of said cable, said protrusion strand being made entirely of a material having a low dielectric constant and high electrical resistence.
