Abstract: In a ground cable to be applied to an on-vehicle wiring harness or the like, the aim is to make it easy and simple to conduct the waterproofing work. A first sealant 6 of the UV-cure type having as a contact angle with respect to the bare conductor 1a of the ground cable 1 an acute one and a viscosity of 15-500 mPa·s is delivered by drops onto the bare conductor. The first sealant 6 is delivered by drops onto a second sealant 7. The first and second sealants 6 and 7 are irradiated by ultraviolet rays. This permits the first sealant 6 to, without the need to suck-decompress the interior of the ground cable 1, by dint of capillarity, spontaneously permeate into the cable core 1b of the ground cable 1 to be then cured. Even in case where a ground terminal 2 has a pair of ground cables 1 crimped thereonto, each ground cable 1 permits an adequate amount of the sealant 6 to, with ease, permeate it.

Abstract: A data communication cable can comprise multiple pairs of twisted conductors. A jacket that extends along the outside surface of the cable can define a longitudinal core, internal to the cable. The conductor pairs can be disposed in the core of the cable along with a foam matrix or a porous filler, with the matrix and the conductors occupying essentially all of the volume of the core. The foam matrix can hold each conductor pair in a respective location within the cable core to control signal crosstalk on each pair. A co-extrusion process can produce the cable via simultaneously extruding the foam matrix and the jacket. A pulling apparatus can feed the conductor pairs though respective ports of an extrusion head-and-die assembly. As one extruder encases the moving conductor pairs in the foam matrix, another extruder forms the jacket over the matrix and the embedded conductors.
