Abstract
Disclosed is a reinforced type high flame retardation fireproof power cable, comprising a plurality of wire cores, wherein the inner core of the wire core is a conductor coated by an insulating layer; the inner wall of the insulating layer is provided with multiple grooves; the multiple wire cores coated by the insulating layer and a reinforced steel wire are intertwisted to be wrapped by a fireproof layer; and the fireproof layer is sequentially wrapped by an oxygen barrier, an inner sheath, an armor, and an outer sheath. The reinforced type high flame retardation fireproof power cable of the utility model adopts a mica tape with high temperature resistance property to be the fireproof layer and is provided with an oxygen barrier, thereby effectively improving the fireproof performance of the electric power cable. The design of employing a reinforced steel wire effectively improves the anti-pulling performance of the power cable. The grooves arranged in the inner wall of the insulating layer effectively improve the heat radiation performance of the power cable during the using process and ensure the security of the power cable. Meanwhile, the outer sheath is made of low smoke halogen free polyolefin material. When a fire hazard happens, the power cable does not release corrosive gas and heavy smoke while being burned, thereby being helpful for the escape and rescue of the personnel.
Description
Technical field
The utility model designs a kind of cable, is specially a kind of reinforced high flame retardant fireproof 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 refractory ability and the tensile property of existing common cross-linked polrvinyl chloride insulated power cable are 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, 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 reinforced high flame retardant fireproof power cable, relatively poor with the fire resistance and the tensile property that solve power cable in the prior art, when breaking out of fire, easily burn, 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 reinforced high flame retardant fireproof power cable, it is characterized in that: include several cores, described several core inner core is conductor, the outside is coated with insulating barrier, evenly be provided with several grooves on the described insulating barrier inwall, be surrounded with flame retardant coating after several cores behind the described coated insulation layer are stranded with the reinforcement steel wire, described flame retardant coating is coated with oxygen barrier layer, inner sheath, armour and oversheath outward successively.
Described a kind of reinforced high flame retardant fireproof power cable is characterized in that: described flame retardant coating is that Mica tape consists of.
Described a kind of reinforced high flame retardant fireproof power cable, it is characterized in that: described inner sheath and oversheath all adopt the low-smoke halogen-free polyolefin 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, and be provided with oxygen barrier layer, the fire resistance of Effective Raise power cable, when cable fire, still can guarantee the integrality of certain hour, adopt the design of strengthening steel wire, effectively promoted the tensile property of cable, the insulating barrier inwall is provided with several grooves, effectively promoted power cable heat dispersion in use, guaranteed the fail safe of cable, oversheath adopts the low-smoke halogen-free polyolefin material to make simultaneously, when breaking out of fire, can not discharge corrosive gas and dense smoke during cable fire, be conducive to fleeing from and rescuing of personnel.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of reinforced high flame retardant fireproof power cable, include several cores 1, several core 1 inner cores are conductor, the outside is coated with insulating barrier 2, evenly be provided with several grooves 3 on insulating barrier 2 inwalls, several cores behind the coated insulation layer 21 with strengthen steel wire 4 and be surrounded with flame retardant coating 5, flame retardant coating 5 outer oxygen barrier layer 6, inner sheath 7, armour 8 and the oversheaths 9 of being coated with successively after stranded.
Flame retardant coating 5 consists of for Mica tape.Inner sheath 7 and oversheath 9 all adopt the low-smoke halogen-free polyolefin material to make.
Claims (3)
