Title:
METHOD FOR CONNECTING RETURN CONDUCTORS OF POWER SUPPLY DC COAXIAL CABLES AND CONNECTION PORTION BETWEEN POWER SUPPLY DC COAXIAL CABLES
Document Type and Number:
WIPO Patent Application WO/2007/142069
Kind Code:
A1
Abstract:
A power supply DC coaxial cable has a main conductor at the center, a main insulating
layer outside the main conductor, and a return conductor comprising a large number
of return conductor wires coaxially twisted outside the main insulating layer.
In a method for connecting the return conductors at the connection portion between
the power supply DC coaxial cables, a plurality of return conductor wires of the
DC coaxial cables on both sides are adjacently arranged to form each return conductor
wire bundle, and the ends of the return conductor wire bundles on both sides are
faced to each other and then welded together. This enables the time required
for welding the return conductor wires to be reduced and provides a method for
connecting the return conductors of DC coaxial cables, which is also applicable
to the return conductor connection between DC coaxial cables each having a different
number of return conductor wires.
