  • Patent number: 10121569
    Abstract: A cable includes electric wires, an outer cover, a first cover, and a second cover. Each of the electric wires includes a conductive core and an insulator covering the conductive core. The outer cover covers the electric wires and extends from a first atmosphere to a second atmosphere less explosive than the first atmosphere. An outer surface of the outer cover is supported by a partition separating the first atmosphere from the second atmosphere. The first cover includes a thermosetting resin and covers an exposed portion of the electric wires, which is not covered by the outer cover in the second atmosphere. The second cover covers the first cover and includes a material higher in fracture strength than the thermosetting resin.
