Cable barrier layer with shielding segments

摘要

A cable that has a cable core that includes at least one conductor that is surrounded by insulation. A barrier layer substantially surrounds the conductor's insulation. The barrier layer may include a plurality of shielding segments. Each of the shielding segments extends substantially around a circumference of the barrier layer. The shielding segments may be spaced from one other to form a discontinuous shield around the conductor.

1. A cable, comprising:
a cable core, comprising:
a plurality of insulated conductors forming at least one twisted insulated conductor pair;one or more barrier layers, each of the one or more barrier layers comprising a substrate layer and a shielding layer, wherein one of the barrier layers surrounds one of the twisted insulated conductor pairs, such that the substrate layer substantially continuously surrounds said twisted insulated conductor pair, the shielding layer comprises a plurality of shielding segments longitudinally spaced apart and extending substantially around an outer surface of the substrate layer, and wherein the shielding layer has gaps in both the circumferential and longitudinal directions; andwherein the total length of the shielding segments or the circumferential gaps for one or more of the at least one twisted insulated conductor pair are at least twice the twist lay of said twisted insulated conductor pair.
