Abstract

An article comprises a plurality of core tubes having coated thereon an insulating wall, a water-blocking layer, a conduit, and an outer jacket. The core tube comprises one or more conductors and is each surrounded by the insulating wall. The core tube can be wrapped with the insulating wall by any means known to one skilled in the art similar to electrical wire making. The insulating wall can be surrounded by the water-blocking layer. The role of the insulating wall is to protect the conductors from external mechanical damage, moisture penetration, and to provide electrical insulation. Such wall can comprise a continuous matrix, generally made of a polymer, optionally containing filler particles that may be inorganic.
