Abstract
The invention relates to a high flame retardant fireproof power cable, which comprises an oxygen-barrier packing layer, wherein a plurality of conductors consisting of a plurality of soft copper wires are arranged in the oxygen-barrier packing layer; a second fireproof layer is arranged outside the oxygen-barrier packing layer; an armor layer is closely coated on the second fireproof layer; and a high flame retardant low smoke zero halogen sheath layer is arranged outside the armor layer. The invention has the advantages that when the high flame retardant fireproof power cable is manufactured, cables with different cores can be manufactured according to requirements of users, and a protective layer of the cable can be designed according to the laying environment of the users.
Description
Technical field
The present invention proposes a kind of occasion of having relatively high expectations to fire protecting performance in skyscraper, market place builet below the ground etc., particularly a kind of high flame retardant fire-type power cable of mainly being applicable to.
Background technology
Along with improving constantly of expanding economy and the people's living standard, the building housing industry is flourish throughout the country, particularly rises sheer from level ground in each big and medium-sized cities as the spring bamboo behind the skyscraper dwelling house elephanta.And high residential building is the same with other skyscraper and luxurious hotel etc. harsher service conditions has been proposed for building wire fireproofing of cable characteristic, security reliability.As fire prevention, explosion-proof, overload capacity is strong, long service life, under Fire Conditions, Fire lift, fire pump need keep the normal operation in the certain hour, cable is the low-smoke low-halogen low toxicity after burning, even the specific (special) requirements such as smokeless halogen-free is nontoxic.
In traditional cable, fireproof cable is to adopt magnesium oxide insulated or mica tape insulation, adopts at last vertical bag argon arc welding copper sheath, and mica tape comes off in combustion process easily, causes insulation property to reduce; Bending property is bad; Manufacturing cost is higher.
Summary of the invention
The present invention seeks to for and a kind of fire-retardant and higher high flame retardant fire-type power cable of fire protecting performance is provided.
For achieving the above object, the present invention solves the scheme that its technical problem takes and is:
This high flame retardant fire-type power cable, comprise the oxygen barrier packed layer, be provided with a plurality of conductors that formed by many soft copper silks in the described oxygen barrier packed layer, described oxygen barrier packed layer is outside equipped with the second fireprotection layer, the outer hard-pressed bale of described the second fireprotection layer has armour, and described armour is outside equipped with high flame resistance, low smoke Halogen outer jacket.
Further, described conductor is surrounded with insulating barrier outward, and described insulating barrier also is provided with auxiliary insulating layer outward.
Compared with prior art, usefulness of the present invention is: this high flame retardant fire-type power cable can be made according to user's requirement the cable of different core numbers during fabrication, and can be according to user's the protective layer that environment can design cable that lays.So that cable can adapt to the use of user under varying environment.It is that the generation of secondary disaster when preventing fire and the noxious substance in the cable material are to the injury of the person that cable adopts the low-smoke bittern-free highly fire-proof cable material of polyolefin.
Description of drawings:
The present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is high flame retardant fire-type power cable structure schematic diagram of the present invention.
Among the figure: 1, conductor; 2, insulating barrier; 3, auxiliary insulating layer; 4, oxygen barrier packed layer; 5, the second fireprotection layer; 6, armour; 7, high flame resistance, low smoke Halogen outer jacket.
Embodiment
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of high flame retardant fire-type power cable shown in Figure 1 comprises oxygen barrier packed layer 4, plays oxygen barrier and fills the rounding effect, is provided with a plurality of conductors 1 that are comprised of many soft copper silks in the described oxygen barrier packed layer 4, and described conductor 1 can also be single conductor
,Described oxygen barrier packed layer 4 is outside equipped with the second fireprotection layer 5; play oxygen barrier and fill the rounding effect; described the second fireprotection layer 5 outer hard-pressed bales have armour 6; described armour 6 adopts galvanized steel strip (or non magnetic steel band or aluminium strip); play protection cable and fireproofing function; described armour 6 is outside equipped with high flame resistance, low smoke Halogen outer jacket 7, plays protection cable and waterproof action radially.
The described conductor 1 outer insulating barrier 2 that is surrounded with, described insulating barrier also is provided with auxiliary insulating layer 3 outward, described insulating barrier 2 adopts two-sided plasticising synthetic mica tape, play main insulation and the fire protecting performance of fireproof cable, described auxiliary insulating layer 3 adopts fire prevention ceramic silicon rubber composite belt, plays the supplementary insulation of fireproof cable and strengthens fire protecting performance.
Producing principle according to the described high flame retardant fire-type of above embodiment power cable is as follows:
High flame retardant fire-type power cable is to adopt 5 class conductors or 1 class conductor structure at the conductor 1(of cable first) go up wrapped fire-resistant isinglass belt as the insulating barrier 2 of cable, then be auxiliary insulating layer 3 at the wrapped fire prevention ceramic silicon rubber composite belt in mica tape outside, then with the cable core stranding, high flame retardant oxygen barrier layer material is extruded as oxygen barrier packed layer 4 in the cable core outside, the wrapped fire prevention ceramic silicon rubber composite belt in oxygen barrier layer material outside is the second fireprotection layer 5, the overlapping wrapped two-layer steel belt layer 6 in fire prevention ceramic silicon rubber composite belt outside is at last at steel belt layer 6(or non magnetic steel band or aluminium strip) outside extrudes high flame resistance, low smoke Halogen outer jacket 7.
This high flame retardant fire-type power cable can be made according to user's requirement the cable of different core numbers during fabrication, and can be according to user's the protective layer that environment can design cable that lays.So that cable can adapt to the use of user under varying environment.It is that the generation of secondary disaster when preventing fire and the noxious substance in the cable material are to the injury of the person that cable adopts the low-smoke bittern-free highly fire-proof cable material of polyolefin.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
