In order to solve the problems, the invention provides a fire-resistant instrument cable.
The utility model provides a fire-resistant instrument cable, includes the array cable core, the cable core include stranded annealed copper conductor, around the copper foil polyester composite shielding area of package outside stranded annealed copper conductor, around the outside mica insulating layer of package at copper foil polyester composite shielding area, the array cable core between be provided with each other around package and the pottery polyolefin of transversal form of personally submitting "3", the both sides of pottery polyolefin all be provided with the compound rope that is used for improving the inside resistant performance of drawing of cable, compound rope between and both sides all be provided with the ethylene propylene rubber insulating rope, the outside crowded package of pottery polyolefin have polytetrafluoroethylene flame retardant layer, the outside crowded package of polytetrafluoroethylene flame retardant layer have low smoke and zero halogen flame retardant polyolefin aluminium foil composite sheath layer.
The composite rope comprises a flame-retardant non-hygroscopic fiber inner core arranged at the central position and a glass fiber cloth anti-burning layer wrapped outside the flame-retardant non-hygroscopic fiber inner core.
The composite ropes are provided with isolating strips with irregular cross sections, and the isolating strips are made of flame-retardant propylene oxide.
The cross section of the ethylene propylene rubber insulating rope is diamond-shaped.
And flame-retardant polypropylene fiber filling layers are arranged between the copper foil polyester composite shielding tape and the mica insulating layer, between the ceramic polyolefin and the mica insulating layer and between the ceramic polyolefin and the polytetrafluoroethylene flame-retardant layer.
The beneficial effects of the invention are as follows: the ceramic polyolefin wound among the plurality of groups of cable cores and having the cross section of 3 is used as a flame retardant layer, so that the cable cores can be rapidly hardened and protected from being influenced by the big fire temporarily when the big fire comes, a life saving time is provided for machinery needing to operate, and the flame retardant performance is good; the composite rope and the ethylene propylene rubber insulating rope with the diamond cross section are used as one of the tensile element and the flame retardance in the cable, so that the problem of unsmooth operation caused by internal hardening can be reduced when the cable is used; meanwhile, the stability of the inside of the cable is improved by matching with the isolation strip with an irregular shape, and the service life of the cable is prolonged.
Drawings
The invention will be further described with reference to the drawings and examples.
FIG. 1 is a schematic diagram of a front view of the present invention;
fig. 2 is an enlarged view of part I of fig. 1 in accordance with the present invention.
Detailed Description
The present invention will be further described in the following to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the present invention easy to understand.
As shown in fig. 1 and 2, a fire-resistant instrument cable comprises an array cable core, wherein the cable core comprises a stranded annealed copper conductor 7, a copper foil polyester composite shielding tape 11 wrapped outside the stranded annealed copper conductor 7 and a mica insulation layer 5 wrapped outside the copper foil polyester composite shielding tape 11, ceramic polyolefin 8 wrapped mutually and with a cross section of a3 shape are arranged between the array cable cores, composite ropes for improving the tensile property inside the cable are arranged on two sides of the ceramic polyolefin 8, ethylene propylene rubber insulation ropes 3 are arranged between the composite ropes and on two sides of the composite ropes, a polytetrafluoroethylene flame-retardant layer 1 is wrapped outside the ceramic polyolefin 8 in an extrusion mode, and a low-smoke halogen-free flame-retardant polyolefin aluminum foil composite sheath layer 2 is wrapped outside the polytetrafluoroethylene flame-retardant layer 1.
The ceramic polyolefin 8 which is wound between the plurality of groups of cable cores and has the cross section of 3 is used as a flame retardant layer, so that the cable cores can be rapidly hardened and protected from being influenced by the big fire temporarily when the big fire comes, a section of life saving time is provided for machinery needing to operate, and the flame retardant performance is good.
The ceramic polyolefin 8 takes polyolefin resin as a base material, and is added with high-efficiency ceramic forming filler, flame retardant and other functional aids, compared with the traditional flame retardant material, the ceramic polyolefin 8 can generate hard ceramic hard shell under the condition of high fire or high temperature, the hard shell does not fall off or melt, can resist water spray and mechanical shock, and has very good heat insulation, fire isolation and water isolation effects.
