The invention relates to an elevator cable core, an elevator cable and an elevator. The elevator cable core comprises a first tensile rope, a cable conductor and a first resistance piece, and the cable conductor extends in the length direction of the first tensile rope and is connected with the first tensile rope. The first resistance piece is used for being in clamping fit with the cable hanging frame and used for increasing the friction force between the first pull-bearing rope and the cable conductor. During installation, the wire hanging frame clamps the position, corresponding to the first resistance piece, of an elevator cable core so as to increase the friction force between the first pull-bearing rope and the cable conductor and avoid relative slippage between the first pull-bearing rope and the cable conductor, so that after the elevator cable is hung and installed, the dead weight of the elevator cable and the pulling force during acceleration and deceleration of the elevator are both borne by the first pull-bearing rope, and the elevator cable is prevented from being damaged. The cable conductor is ensured not to be stretched along with the back-and-forth operation of the elevator so as not to cause the reduction of the electrical performance of the elevator cable, and the cable conductor is ensured not to be snapped along with the back-and-forth operation of the elevator so as to ensure the safe operation of the elevator.

    本发明涉及一种电梯电缆缆芯、电梯电缆及电梯。电梯电缆缆芯包括第一承拉绳、电缆导体及第一阻力件,电缆导体沿第一承拉绳的长度方向延伸,并与第一承拉绳相连接。第一阻力件用于与挂线架夹紧配合,用以增加第一承拉绳与电缆导体之间的摩擦力。安装时,挂线架夹紧电梯电缆缆芯对应第一阻力件的位置,以增加第一承拉绳和电缆导体之间的摩擦力,避免第一承拉绳和电缆导体之间发生相对滑移,使得电梯电缆悬挂安装后,其自重以及电梯加减速时的拉力全部由第一承拉绳承受,保证电缆导体随着电梯的往返运行不会被拉长而导致电梯电缆的电气性能下降,同时保证电缆导体随着电梯的往返运行也不会被拉断,确保电梯安全运行。
