Abstract
Disclosed is a high flame retardation fireproof power cable, comprising multiple wire cores, wherein the inner core of the wire core is a conductor wrapped by an insulating layer; multiple wire cores are intertwisted and then wrapped by a fireproof layer; the fireproof layer is sequentially wrapped by an inner sheath, an armor, and an outer sheath; and the inner wall of the insulating layer is evenly provided with multiple grooves filled with inert gas. The high flame retardation fireproof power cable of the utility model adopts a high-temperature-resisting mica tape to be the fireproof layer, thereby effectively improving the fireproof performance of the power cable and ensuring the integrity for certain time when the cable is burned. The inner wall of the insulating layer is provided with multiple grooves filled with inert gas, thereby effectively improving the heat radiation performance and flame retardation performance of the power cable during the using process and ensuring the security of the power cable.
Description
Technical field
The utility model designs a kind of cable, is specially a kind of high flame retardant fire proof power 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 the refractory ability of existing common cross-linked polrvinyl chloride insulated power cable is relatively poor, 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, and power cable can produce heat unavoidably in the process of transferring electric power, and the heat dispersion of existing power cable is relatively poor, and there is potential safety hazard in long-time the use.
The utility model content
The purpose of this utility model provides a kind of high flame retardant fire proof power cable, poor with the fire resistance that solves power cable in the prior art, when breaking out of fire, burn easily, be unfavorable for that evacuating personnel withdraws the problem with fire rescue, heat dispersion is not good simultaneously, has the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of high flame retardant fire proof power cable, it is characterized in that: include several cores, the inner core of described several cores is conductor, the outside is coated with insulating barrier, be surrounded with flame retardant coating after described several core is stranded, described flame retardant coating is coated with inner sheath, armour and oversheath outward successively, evenly is provided with several grooves on the described insulating barrier inwall, is filled with inert gas in the described groove.
Described a kind of high flame retardant fire proof power cable is characterized in that: described flame retardant coating is that Mica tape consists of.
Described a kind of high flame retardant fire proof power cable is characterized in that: described inner sheath and oversheath all adopt silastic material to make.
The beneficial effects of the utility model are:
The utility model adopts resistant to elevated temperatures mica tape as flame retardant coating, the fire resistance of Effective Raise power cable, when cable fire, still can guarantee the integrality of certain hour, the insulating barrier inwall is provided with several grooves, be filled with inert gas in the groove, effectively promote power cable heat dispersion and fire resistance in use, guaranteed the fail safe of cable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of high flame retardant fire proof power cable, include several cores 1, the inner core of several cores 1 is conductor, the outside is coated with insulating barrier 2, is surrounded with flame retardant coating 4, flame retardant coating 4 outer inner sheath 5, armour 6 and the oversheaths 7 of being coated with successively after several core 1 is stranded, evenly be provided with several grooves 3 on insulating barrier 2 inwalls, be filled with inert gas in the groove 3.
Flame retardant coating 4 consists of for Mica tape.Inner sheath 5 and oversheath 7 all adopt silastic material to make.
Claims (3)
1. high flame retardant fire proof power cable, it is characterized in that: include several cores, the inner core of described several cores is conductor, the outside is coated with insulating barrier, be surrounded with flame retardant coating after described several core is stranded, described flame retardant coating is coated with inner sheath, armour and oversheath outward successively, evenly is provided with several grooves on the described insulating barrier inwall, is filled with inert gas in the described groove.
2. a kind of high flame retardant fire proof power cable according to claim 1 is characterized in that: described flame retardant coating is that Mica tape consists of.
