Abstract
Abstract A flat type feeder cable useful for transmitting electrical energy from a stationary source to a moving apparatus, which has a plurality of spaced apart strength members each with their respective axes arranged in a line and in substantially coplanar relationship with one another; a plurality of strand members stranded together about each of the strength members to form a core, the strand members themselves being composed of a plurality of electrical conductors circumscribed by a sheath, and are "S-Z" stranded so that they contain first and second alternatingly repeating substantially equal first and second sections, each of said first sections having a common direction and degree of lay and each of said second sections also having a common direction and degree of lay substantially equal opposite to that of the first sections, and, a jacket of flexible material circumscribing the core members.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
A flat type feeder cable useful for transmitting electrical energy from a stationary source to a moving apparatus comprising: (a) a plurality of spaced apart strength members each with their respective axes arranged in a line and in substantially coplanar relationship with one another; (b) a plurality of strand members stranded together about each of said strength members to form a core, said strand members comprising a plurality of electrical conductors circumscribed by a sheath and forming first and second alternatingly repeating, substantially equal length, first and second sections, each of said first sections having a common direction and degree of lay and each of said second sections also having a common direction and degree of lay substantially equal to but opposite to that of the first sections; and (c) a jacket of flexible material circumscribing said core members.
