Embodiment 1

[0040] see figure 1 The accompanying cable for a thin-walled light-duty elevator includes a flat accompanying cable body 100, an optical fiber cable 110 is arranged in the middle of the accompanying cable body 100, and two control cables 120 are respectively arranged on both sides of the optical fiber cable 110. Each control cable 120 includes a filling core 121 and several wire cores 122 stranded on the periphery of the filling core 121, each wire core 122 includes a conductor 122a and a PVC insulating layer 122b covering the periphery of the conductor 122a, and the interior of the accompanying cable body 100 Steel wire ropes 130 are also arranged on both sides.

[0041] The PVC insulating layer in the present embodiment is as follows according to the formula of weight part ratio:

[0042] 45 parts of PVC resin,

[0043] Dioctyl terephthalate 18 parts,

[0044] 3 parts of chlorinated paraffin,

[0045] Environmental stabilizer 2 parts,

[0046] Bisphenol A 0.08 parts,

...

Embodiment 2

[0054] The structure in this embodiment is roughly the same as that in Embodiment 1, and the difference is that the PVC insulating layer in this embodiment is formulated as follows according to the weight ratio:

[0055] 50 parts of PVC resin,

[0056] Dioctyl terephthalate 20 parts,

[0057] Chlorinated paraffin 4 parts,

[0058] 3 parts of environmental stabilizer,

[0059] Bisphenol A 0.1 parts,

[0060] 0.5 part of 551 processing aid,

[0061] 5 parts clay,

[0062] CaCO 3 15 servings,

[0063] PE wax 0.1 part,

[0064] 0.2 parts of stearic acid,

[0065] Carbon black 2.25 parts.

Embodiment 3

[0067] The structure in this embodiment is roughly the same as that in Embodiment 1, and the difference is that the PVC insulating layer in this embodiment is formulated as follows according to the weight ratio:

[0068] 55 parts of PVC resin,

[0069] Dioctyl terephthalate 22 parts,

[0070] Chlorinated paraffin 5 parts,

[0071] 3 parts of environmental stabilizer,

[0072] Bisphenol A 0.12 parts,

[0073] 0.7 part of 551 processing aid,

[0074] 7 parts clay,

[0075] CaCO 3 20 copies,

[0076] 0.12 parts of PE wax,

[0077] 0.3 parts of stearic acid,

[0078] 2.5 parts of carbon black.

[0079] The weight of PVC insulation per core of traditional cables is about 4.7kg / km. After using the PVC insulation layer of the present invention, the weight of insulation PVC per core can be reduced to 1.7kg / km, and the insulation weight is reduced by about 63%. The accompanying cable produced by the invention has the characteristics of small size, light weight, convenient in...

Abstract

The invention discloses a thin-walled light photoelectric composite elevator accompanying cable, which comprises a flat accompanying cable body, an optical fiber cable is arranged in the middle of the accompanying cable body, and several control cables are arranged on both sides of the optical fiber cable. Each control cable includes a filler core and several wire cores stranded on the outer periphery of the filler core, each wire core includes a conductor and a PVC insulation layer covering the periphery of the conductor, and it is characterized in that the PVC insulation layer is in accordance with The formula by weight is as follows: 45-55 parts of PVC resin, 18-22 parts of dioctyl terephthalate, 3-5 parts of chlorinated paraffin, 2-3 parts of environmental stabilizer, 0.08-0.12 parts of bisphenol A , 0.3-0.7 parts of processing aids, 3-7 parts of pottery clay, CaCO 3 10-20 parts, 0.08-0.12 parts of PE wax, 0.1-0.3 parts of stearic acid, 2-2.5 parts of carbon black.

Description

technical field [0001] The invention relates to the field of elevator cables, in particular to a thin-walled light photoelectric composite elevator accompanying cable. Background technique [0002] The insulation and sheath of the traditional accompanying cable are relatively thick, which increases the weight of the entire cable and affects the stability of the elevator during operation. The impact is more obvious when the number of cores is large and the suspension length is long. It is necessary to increase the heavy counterweight to maintain the elevator. The balance of the elevator increases the energy consumption of the elevator. The accompanying cable also includes a plurality of communication cables: a video communication cable, a traffic communication cable, an audio transmission cable, and a network cable communication cable. Numerous communication cables increase the cost of the cables, making it troublesome for customers to install and use, and there is a risk of...
