Abstract
A kind of new anti-explosion cable of this practicality.This utility model includes insulated wire cores, it is characterized in that：Sheath is provided with outside described insulated wire cores, described sheath connects outer jacket by a pack support, steel wire armor layer is provided with outside described outer jacket, flame-retardant layer is provided with outside described steel wire armor layer, arch support of the described support using semicircle, outer jacket described in the top connection of arch support, the sheath described in the Liang Ge foots connection of arch support.This utility model can complex environment under or be used as the transmission electric energy or signal of telecommunication under having blast, the occasion of high-strength mechanical impact, explosion-proof and shock resistance is good.
Description
Technical field：
This utility model is related to a kind of anti-explosion cable, belongs to field of cables.
Background technology：
Power plant, transformer station and industrial and mining establishment all use power cable in a large number, once cable blast on fire, it will cause tight
Weight fire and power outage, additionally, a large amount of dense smokes and poison are produced during cable fire, not only pollute environment, and jeopardize people's
Life security.For this purpose, it should be noted that the fire prevention of power cable.Electric cable explosion main cause on fire includes：
1）For current most conventional cable, insulant such as polyethylene, polrvinyl chloride, crosslinking used is poly-
Ethylene etc. is high molecular polymer, at high temperature can spontaneous combustion, and when bunch of cables is constituted the temperature that is ignited than spontaneous combustion temperature
Degree is low.
2）When cable occurs ground connection and short circuit accident, relay protection failure causes serious two spontaneous combustion of overcurrent of cable.
3）Conductor connection at cable intermediate joint not closely, causes contact resistance big, causes cable hot-spot and spontaneous combustion.
4）Cable structures inner waterproofing improper measures, cause cable by water retting, and its insulation resistance declines, breakdown strength drop
It is low, easily cause cable grounding or short circuit accident and cause fire.
5）Cable long-play, the overload capacity for the insulant of cable is can bear more than service life
Difference, the aging speed of insulation are faster than new cable, and autoignition temperature is also reduced a lot, easily causes fire.
In order to solve the above problems, Chinese patent CN2012204089167 discloses a kind of anti-explosion cable, and which is included from interior
Set gradually to outward as insulation core wire, inner restrictive coating, steel wire armor layer, fire-retardant external sheath layer, it is characterised in that：The interior shield
Space is left between jacket layer and insulation core wire, insulation core wire can be moved freely in sheath.The patent is by for load-bearing
Pressure is all placed on sheath, and as insulated wire cores can be moved freely in sheath, causes sheath pressure-bearing excessive,
Explosion-proof effect is not good.
Utility model content：
The purpose of this utility model is to provide a kind of anti-explosion cable for above-mentioned problem, can complex environment under
Or have blast, be used as the transmission electric energy or signal of telecommunication under the occasion of high-strength mechanical impact, explosion-proof and shock resistance is good.
Above-mentioned purpose is realized by following technical scheme：
A kind of anti-explosion cable, including insulated wire cores, are provided with sheath, described sheath outside described insulated wire cores
Outer jacket is connected by a pack support, steel wire armor layer is provided with outside described outer jacket, outside described steel wire armor layer
Flame-retardant layer is provided with, described support adopts the arch support of semicircle, the outer jacket described in the top connection of arch support, arch
Sheath described in the Liang Ge foots connection of support.
Described anti-explosion cable, described insulation core wire include conductor and the insulating barrier being wrapped in outside conductor.
Described anti-explosion cable, is filled with fire proofing implant between described sheath and described outer jacket.
Described anti-explosion cable, the number of the arch support of described semicircle is even number.
Beneficial effect：
Outside of the present utility model is provided with flame-retardant layer, and fire proofing is filled between sheath and outer jacket,
Good flame retardation effect, while being provided with arch support between sheath of the present utility model and outer jacket, is difficult using arch support
Deformation and the good inherent character of compressive property so that cable explosion-proof of the present utility model and shock resistance are good.
The number of arch support of the present utility model is set to even number, further increases its shock proof performance.
Description of the drawings：
Fig. 1 is structural representation of the present utility model.
In figure：1st, sheath；2nd, support；3rd, outer jacket；4th, steel wire armor layer；5th, flame-retardant layer；6th, conductor；7th, insulating barrier；
8th, fire proofing implant.
Specific embodiment：
Embodiment 1：
As shown in figure 1, a kind of anti-explosion cable of the present embodiment, including insulated wire cores, arrange outside described insulated wire cores
There is sheath 1, described sheath connects outer jacket 3 by a pack support 2, wire armoring is provided with outside described outer jacket
Layer 4, is provided with flame-retardant layer 5 outside described steel wire armor layer, described support adopts the arch support of semicircle, arch support
The described outer jacket of top connection, the sheath described in the Liang Ge foots connection of arch support.
Anti-explosion cable described in the present embodiment, described insulation core wire include conductor 6 and are wrapped in exhausted outside conductor
Edge layer 7.
Anti-explosion cable described in the present embodiment, is filled with fire proofing between described sheath and described outer jacket
Implant 8.
Anti-explosion cable described in the present embodiment, the number of the arch support of described semicircle is even number.
Technological means disclosed in this utility model scheme are not limited only to the technological means disclosed in above-mentioned technological means, also
Including the technical scheme being made up of above technical characteristic equivalent.Unaccomplished matter of the present utility model, belongs to this area skill
The common knowledge of art personnel.
