升降机用橡套软电缆制造技术

本实用新型专利技术公开了一种升降机用橡套软电缆，包括绝缘线芯和填充物，所述的绝缘线芯由在内的导体和包覆在导体外的绝缘层构成，若干条绝缘线芯环绕绞合在填充物上形成缆芯，在缆芯的表面上直接包覆有护套层，且所述缆芯与护套层粘接在一起形成一个整体。本实用新型专利技术将填充物与绝缘层粘接在一起，并在缆芯的表面上直接包覆护套层，通过硫化使缆芯与护套层粘接在一起形成一个整体，从而避免缆芯与护套层之间的相对移动，因而能保证电缆在移动时绝缘线芯的受力均匀，从而延长使用寿命；另一方面，绝缘线芯采用6类导体，再结合缩小缆芯节距来增加电缆的柔软性，以延长导体被拉断的时间，从另一方面进一步延长电缆的使用寿命。（*该技术在2023年保护过期，可自由使用*）

Rubber sheathed flexible cable for elevator

The utility model discloses a soft rubber cable hoist, including insulated wire core and the filler, the conductor insulation wire core comprises, and coated on the outside of the conductor insulating layer, a plurality of insulated wire core stranded around the cable core is formed in a filler, on the surface of the cable core directly coated with a protective cover layer, wherein the cable core and sheath bonded together to form a whole. The utility model combines the filler and the insulating layer are bonded together, and the surface of the cable core coated directly on the jacket layer, through vulcanization makes the cable core and sheath bonded together to form a whole, so as to avoid the relative movement between the cable core and a sheath layer, which can guarantee the cable in the movement of insulation the uniform stress, thereby prolonging the service life; on the other hand, using 6 kinds of insulated wire core conductor, combined with reduced cable core pitch to increase the flexibility of the cable, to extend the conductor pulled off the time, from the further extension of the service life of the cable on the other hand.
