レベータケーブル。1. In an elevator cable that receives and receives signals between the elevator car and the machine room, a plastic foam layer is provided between the wire core and the sheath, which are made by insulating the conductor,
An optical fiber is partially housed within the foam layer, and the foam layer is configured such that a foaming rate in a portion near the outer periphery of the optical fiber is larger than that in other portions. Optical fiber composite elevator cable. , 72 The plastic foam layer is made of polyurethane with a foaming rate of 60 to 70% near the outer periphery of the optical fiber, and the other part is made of crosslinked polyethylene with a foaming rate of 30 to 50%. The optical fiber composite elevator cable according to item 1.
