Abstract
The utility model discloses a high-flame retardant fireproof power cable which comprises a plurality of insulating wire cores, wherein a conductor is served as the internal core of each insulating wire core; a fireproof layer and an insulating layer are sequentially wrapped outside each insulating wire core; after being twisted, the plurality of insulating wire cores are wrapped with taped coverings; and an oxygen separating layer, an internal protective sleeve, an armour layer and an external protective sleeve are sequentially wrapped outside each taped covering. According to the high-flame retardant fireproof power cable, the high-temperature resistant mica is served as the fireproof layer, and the oxygen separating layer is arranged, so that the fireproof performance of a power cable is effectively improved; the integrity of the cable can be kept at a certain time during being burnt; meanwhile, the external protective sleeve is manufactured by low-smoke halogen-free polyolefin material; once fire occurred, the cable cannot be burnt to generate corrosive gas and dense smoke, thus, the benefit is provided to people to escape and rescue.
Description
Technical field
The utility model designs a kind of cable, is specially a kind of high flame retardant fireproof power cable.
Background technology
Cable is in the development of the national economy; Carrier as transmitting electric power and diffusing information has played enormous function, along with quickening of urbanization process; The fast development of electric power transmission and communication; Make people to electric wire require increasingly highly, not only require cable to have the characteristics of safety and environmental protection, and have lower cost.
Yet existing common cross-linked polrvinyl chloride insulated power cable scarcely possesses refractory ability; Can not under flame condition, keep supply line to continue operation safely and steadly, when breaking out of fire, cable can be very fast fire burns; Stop power supply, be unfavorable for personnel's evacuation egress and fire rescue.
The utility model content
The purpose of the utility model provides a kind of high flame retardant fireproof power cable, and is poor with the fire resistance that solves power cable in the prior art, when breaking out of fire, burns easily, is unfavorable for that evacuating personnel withdraws the problem with fire rescue.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of high flame retardant fireproof power cable; It is characterized in that: include several insulated wire cores; The inner core of said insulated wire cores is a conductor; The outside is coated with flame retardant coating and insulating barrier successively, is surrounded with lapping layer after several insulated wire cores are stranded, and said lapping layer is coated with oxygen barrier layer, inner sheath, armour and oversheath outward successively.
Described a kind of high flame retardant fireproof power cable is characterized in that: said flame retardant coating is the wrapped formation of mica tape.
Described a kind of high flame retardant fireproof power cable is characterized in that: said inner sheath and oversheath all adopt the low-smoke halogen-free polyolefin material to process.
The beneficial effect of the utility model is:
The utility model adopts resistant to elevated temperatures mica tape as flame retardant coating; And be provided with oxygen barrier layer, and effectively improve the fire resistance of power cable, when cable fire, still can guarantee the integrality of certain hour; Oversheath adopts the low-smoke halogen-free polyolefin material to process simultaneously; When breaking out of fire, can not discharge corrosive gas and dense smoke during cable fire, help fleeing from and rescuing of personnel.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model includes several insulated wire cores, and the inner core of insulated wire cores is a conductor 1, and the outside is coated with flame retardant coating 2 and insulating barrier 3 successively; Be surrounded with lapping layer 4 after several insulated wire cores are stranded, lapping layer 4 outer oxygen barrier layer 5, inner sheath 6, armour 7 and the oversheaths 8 of being coated with successively.
Flame retardant coating 2 is the wrapped formation of mica tape.Inner sheath 6 all adopts the low-smoke halogen-free polyolefin material to process with oversheath 8.
Claims (3)
1. high flame retardant fireproof power cable; It is characterized in that: include several insulated wire cores; The inner core of said insulated wire cores is a conductor; The outside is coated with flame retardant coating and insulating barrier successively, is surrounded with lapping layer after several insulated wire cores are stranded, and said lapping layer is coated with oxygen barrier layer, inner sheath, armour and oversheath outward successively.
2. a kind of high flame retardant fireproof power cable according to claim 1 is characterized in that: said flame retardant coating is the wrapped formation of mica tape.
3. a kind of high flame retardant fireproof power cable according to claim 1 is characterized in that: said inner sheath and oversheath all adopt the low-smoke halogen-free polyolefin material to process.
