Abstract
The utility model discloses a kind of increase-volume flame-proof wire, including conductor, 0.25~0.55mm is extruded outside conductor2Insulating barrier, 0.25~0.55mm is extruded in cable outermost layer2Oversheath；Elastic reinforcement core is provided with described conductor；Described oversheath is provided with a symmetrical through hole, and thermometric chip is provided with the through hole；The rhombus groove of multiple anti-extrusions is additionally provided with oversheath.Ceramic silicon rubber insulating barrier is extruded outside conductor, its sintering that foamed in the short time in high temperature or after meeting fire forms stiff shell, and housing has and keeps up, the characteristic of not resume combustion, the use of the material can make electric wire normal operating temperature improve 20 DEG C, current-carrying capacity lifting 20%~30%；Extruded outside insulating barrier low-smoke halogen-free polyolefin material make electric wire have it is fire-retardant, burning when the low environmental-protecting performance of smoke amount, compared to material cost all can also be greatly reduced using Ceramic silicon rubber, be conducive to market spread.
Description
Technical field
The utility model is related to electric wire to manufacture field, specifically a kind of increase-volume flame-proof wire.
Background technology
Modern metropolitan cities are built to fire protection requirement more and more higher, and traditional electric wire has been continued to develop no longer with material technology
Strict demand of the building to fire protecting performance can be met, and common flame-proof wire is due to holding at high price it is difficult to spread should
With；Existing fireproof cable anti-extrusion and is not easily broken off, and does not also have from temp sensing function.
Utility model content
The utility model is in order to solve problems of the prior art, there is provided it is a kind of meet electric wire fire prevention, environmental protection
Technical requirements, can increase electric wire current-carrying capacity again, while manufacturing cost is less than traditional increase-volume flame-proof wire.
A kind of increase-volume flame-proof wire described in the utility model, including conductor, extrude 0.25~0.55mm outside conductor2Absolutely
Edge layer, 0.25~0.55mm is extruded in cable outermost layer2Oversheath；Elastic reinforcement core is provided with described conductor；Described is outer
Sheath is provided with a symmetrical through hole, and thermometric chip is provided with the through hole；The rhombus of multiple anti-extrusions is additionally provided with oversheath
Groove.
Further improve, described insulating barrier is Ceramic silicon rubber insulating barrier.
Further improve, described external sheath layer is low-smoke halogen-free polyolefin oversheath.
The beneficial effects of the utility model are：Compared with prior art, ceramic SiClx is extruded outside the utility model conductor
Rubber insulation, its sintering that foamed in the short time in high temperature or after meeting fire forms stiff shell, and housing has and keeps up, not resume combustion
Characteristic, the use of the material can make electric wire normal operating temperature improve 20 DEG C, current-carrying capacity lifting 20%~30%；Outside insulating barrier
Extrude low-smoke halogen-free polyolefin material make electric wire have it is fire-retardant, burning when the low environmental-protecting performance of smoke amount, compared to all use make pottery
Porcelain SiClx rubber can also be greatly reduced material cost, be conducive to market spread；The New-style electrical wire is compared to low with tradition
Cigarette Halogen fire-resistant wires are lower due to eliminating wrapped mica operation cost of manufacture.In addition, the utility model is additionally provided with thermometric core
Piece, can detect the temperature of cable, can be very good to control the temperature of cable, in case cable temperature is too high to cause spontaneous combustion；Also
Rhombus groove is provided with, cable is effectively prevented and is extruded by the external world so that distortion of the cable and fracture；Also the heart is provided with the conductor
Elastic reinforcement member, in the presence of elasticity, is difficult so that cable breakdown.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of increase-volume flame-proof wire described in the utility model, including conductor 1, extruded outside conductor 1
0.25~0.55mm2Insulating barrier 2,0.25~0.55mm is extruded in cable outermost layer2Oversheath 3；Elasticity is provided with described conductor
Strengthening core 4, in the presence of elasticity, cable core is difficult to be broken off；Described oversheath is provided with a symmetrical through hole 5, the through hole
Thermometric chip 6 is inside provided with, the temperature change of cable is can detect；Multiple rhombus grooves 7 are additionally provided with oversheath, can prevent cable from existing
When extruding by the external world, certain buffering is played, be difficult to make the deformation of line layer and extruding in cable.
Ceramic silicon rubber insulating barrier is extruded outside conductor, its sintering that foamed within the short time after high temperature or chance fire forms hard
Housing, with keeping up, the characteristic of not resume combustion, the use of the material can make electric wire normal operating temperature improve 20 DEG C to housing,
Current-carrying capacity lifting 20%~30%；Extruded outside insulating barrier low-smoke halogen-free polyolefin material make electric wire have it is fire-retardant, burning when smoke amount
Low environmental-protecting performance, compared to material cost all can also be greatly reduced using Ceramic silicon rubber, is conducive to market large area
Promote.The New-style electrical wire compared to lower due to eliminating wrapped mica operation cost of manufacture with traditional low-smoke zero-halogen fire-resistant electric wire,
New-style electrical wire 1.5mm2And 2.5mm2Respectively than WDZN-BY model electric wires low cost 10% and 12%.
The utility model concrete application approach is a lot, and the above is only preferred embodiment of the present utility model, should
Point out, for those skilled in the art, on the premise of the utility model principle is not departed from, can also make
Go out some improvement, these improvement also should be regarded as protection domain of the present utility model.
