PROBLEM TO BE SOLVED: To provide a partition penetration cable unit capable of preventing water, flame, or smoke from trespassing, from an external space in which a water flood or fire has occurred, on an internal space in which a facility and the like to be protected are provided through a partition and capable of preventing flame or smoke from trespassing, from an internal space in which fire has occurred, on an external space in which a facility and the like to be protected are provided through a partition.SOLUTION: A partition penetration cable unit comprises: a conductor connection part that connects a conductor of a first insulation core wire 10A exposed from a first cable end 1A with a conductor of a second insulation core wire 10B exposed from a second cable end 1B, through a crimp sleeve having a section wall part; a tube enclosure part 5 that encloses an end of the first insulation core wire 10A, the conductor connection part, and an end of the second insulation core wire 10B, by using a heat contraction tube; a pipe member 60 that encloses the first cable end 1A, the tube enclosure part 5, and the second cable end 1B; fire resistant wall parts 71 and 72 formed inside of both ends of the pipe member 60; and a water-pressure resistant wall part 73 formed inside the pipe member 60's middle part in which the tube enclosure part 5 is disposed.SELECTED DRAWING: Figure 6 |
