Abstract
The utility model discloses a high-temperature single-core cable and belongs to the cable field. The high-temperature single-core cable includes a conductor, a thin wall shielding layer arranged at the outer side of the conductor, an insulation layer arranged at the outer side of the thin wall shielding layer, a tinned copper wire shielding layer arranged the outer side of the insulating layer, a high-flame retardant oxygen barrier layer arranged the outer side of the tinned copper wire shielding layer, an outer protective layer arranged at the outer side of the high-flame retardant oxygen barrier layer, and a fire-retardant layer is arranged at the outer side of the outer protective layer, and a sheath arranged at the outer side of the fire-retardant layer. The high-temperature single-core cable of the utility model has the advantages of high temperature resistance, simple and reasonable structure, easy manufacture, low cost and excellent use performance.
Description
Technical field
The utility model relates to field of cables, specifically, relates to a kind of high temperature single-core cable.
Background technology
Along with China's expanding economy, various architectural engineerings are with unprecedented scale and speed development, also more and more higher to the requirement of electric equipment.In recent years, because the electric fire causing increases gradually, and wherein because the fire that electric wire is former thereby cause occupies sizable ratio, due to the cable using at present, it in use easily produces cracking phenomena, and resistance to elevated temperatures is poor, when running into fire, make troubles to disaster relief personnel, thus the potential safety hazard of causing.
Utility model content
The technical problem that 1, will solve
The purpose of this utility model is to provide a kind of low smoke and zero halogen, nontoxic, fire-retardant and have a high temperature single-core cable of higher resistance to elevated temperatures.
2, technical scheme
For achieving the above object, the utility model adopts following technical scheme:
A kind of high temperature single-core cable, comprise conductor, be arranged on the thin-walled screen in conductor outside, be arranged on the insulating barrier in thin-walled screen outside, be arranged on the tinned copper wire screen in insulating barrier outside, be arranged on the high flame retardant oxygen barrier layer in tinned copper wire screen outside, be arranged on the outer jacket in high flame retardant oxygen barrier layer outside, be arranged on flame-retardant layer and the sheath that is arranged on flame-retardant layer outside outside outer jacket.
Further, described conductor is for being formed by 19 soft annealing tin-coated copper wire strandings.
Further, the material of described insulating barrier is foam crosslinked polyethylene, has increased insulating properties, has improved coefficient of safety.
Further, described flame-retardant layer is glass fabric.
Further, the material of described sheath is that model is the crosslinked polyethylene of EM104.
3, beneficial effect
The utility model adopts cross-linked polyolefin oversheath, can effectively prevent that the phenomenon of cracking from use appearring in cable, avoids affecting the performance of cable; The utility model adopts low smoke and zero halogen material, and a large amount of toxic smog gases of having avoided normal cable to produce have improved the efficiency of disposal under hazardous condition and escape, rescue effectively; The utlity model has higher resistance to elevated temperatures, rational in infrastructure simple, easy to manufacture, cost is low, and serviceability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, conductor, 2, thin-walled screen, 3, insulating barrier, 4, tinned copper wire screen, 5, high flame retardant oxygen barrier layer, 6, outer jacket, 7, flame-retardant layer, 8, sheath.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
As shown in Figure 1, a kind of high temperature single-core cable, comprise conductor 1, be arranged on the thin-walled screen 2 in conductor 1 outside, be arranged on the insulating barrier 3 in thin-walled screen 2 outsides, be arranged on the tinned copper wire screen 4 in insulating barrier 3 outsides, be arranged on the high flame retardant oxygen barrier layer 5 in tinned copper wire screen 4 outsides, be arranged on the outer jacket 6 in high flame retardant oxygen barrier layer 5 outsides, be arranged on the flame-retardant layer 7 and the sheath 8 that is arranged on flame-retardant layer 7 outsides in outer jacket 6 outsides.
