Abstract
The utility model discloses a high temperature resistant fireproof cable comprising a plurality of cores, each of which is sequentially wrapped by an insulation layer and a mica tape fireproof layer. An inner side of the insulation layer is filled with inert gas. A plurality of insulation cores, which are wrapped by the fireproof layers, are intertwisted together, and are wrapped by a taped covering in a coiled manner. An inner side of the taped covering is filled with glass fiber yarns, and an outer side of the taped covering is sequentially wrapped by an inner sheath, an oxygen-isolating layer, an armoring layer, and an outer sheath. In the utility model, the mica tape fireproof layers are provided in a wrapped manner, the design of disposing the inert gas in the insulation layers is adopted, the oxygen-isolating layer is provided, and the taped covering is filled with the high temperature resistant glass fiber yarns, therefore the high temperature resistant performance and the fireproof performance of the cable can be effectively improved, and the cable provided in the utility model can be used in occasions having high requirements of high temperature resistant performance and fireproof performance. The high temperature resistant fireproof cable has advantages of good wear resistant performance, mechanical strength, and strong adaptability in severe use environment.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of fire resistant cable.
Background technology
Cable is in the development of the national economy, as the carrier that transmits electric power and diffuse information, played huge effect, quickening along with urbanization process, the fast development of electric power transmission and communication, so that people are more and more higher to the requirement of electric wire, not only require cable to have the characteristics of safety and environmental protection, and have lower cost.
Yet existing common insulated cable mostly high temperature resistant, fire resistance property is relatively poor, do not reach instructions for use, can not under flame condition, keep supply line to continue safely and steadly operation, when breaking out of fire, cable can very fast ignition, stop power supply, be unfavorable for personnel's evacuation egress and fire rescue.
The utility model content
The purpose of this utility model provides a kind of fire resistant cable, with solve cable in the prior art high temperature resistant, fire protecting performance is relatively poor, can not reach the problem of instructions for use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of fire resistant cable, it is characterized in that: include several cores, every core is coated with insulating barrier and mica tape flame retardant coating outward successively, be filled with inert gas in the described insulating barrier, be surrounded with lapping layer after insulated wire cores behind several coating flame retardant coatings is stranded, be filled with glass cord in the described lapping layer, described lapping layer is coated with inner sheath, oxygen barrier layer, armour and oversheath outward successively.
Described a kind of fire resistant cable is characterized in that: described oxygen barrier layer is made by aluminium hydroxide or magnesium hydroxide material.
Described a kind of fire resistant cable is characterized in that: described inner sheath adopts the perfluoroethylene-propylene material to make.
Described a kind of fire resistant cable is characterized in that: described oversheath adopts low cigarette IXPE material to make.
The beneficial effects of the utility model are:
The utility model adopts Mica tape that flame retardant coating is arranged, be filled with the design of inert gas in the insulating barrier, and be provided with oxygen barrier layer and resistant to elevated temperatures glass cord and fill, high temperature resistant, the fire protecting performance of cable have effectively been promoted, can be applied to the high temperature resistant and higher place of fire protection requirement, the utility model also has good resistance to wear and mechanical strength, and is stronger to the adaptability of abominable environment for use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of fire resistant cable, include several cores 1, every core 1 outer insulating barrier 2 and the mica tape flame retardant coating 3 of being coated with successively, be filled with inert gas in the described insulating barrier 2, be surrounded with lapping layer 4 after insulated wire cores behind several coating flame retardant coatings 3 is stranded, be filled with glass cord 5 in the described lapping layer 4, described lapping layer 4 outer inner sheath 6, oxygen barrier layer 7, armour 8 and the oversheaths 9 of being coated with successively.
Oxygen barrier layer 7 is made by aluminium hydroxide or magnesium hydroxide material.Inner sheath 6 adopts the perfluoroethylene-propylene material to make.Oversheath 9 adopts low cigarette IXPE material to make.
