Description
Technical Field
The utility model relates to a cable, more specifically be a shock-resistant high safe environmental protection cable that sprays.
Background
Along with the application of various organic decorative materials and the sharp increase of electrical loads, the probability of fire occurrence is directly and greatly improved, safe and effective rescue is provided for guaranteeing the occurrence of fire, higher safety and reliability requirements are provided for special power supply equipment such as fire elevators, fire pumps, fire smoke exhaust fans, emergency evacuation lighting and the like in important places such as subways, light rails, airports, high-rise buildings and the like, so that smoothness of electric power and information control can be guaranteed under severe fire environment conditions such as smashing by falling objects or impact by fire water flow and the like, secondary damage caused by smoke, toxic gas and the like is reduced, longer time is strived for escape and fire rescue of people, life and property safety of people is guaranteed to the maximum extent, and related performances of the existing electric wires and cables cannot meet the requirements.
Disclosure of Invention
The utility model aims at providing a have excellent fire prevention fire behaviour, anti mechanical shock and water-fast spraying performance, have excellent green performance simultaneously, receive crowded, press, pound or by extreme abominable conflagration environmental condition such as water-hammer under still can last circular telegram and can normal operating several hours a shock-resistant high safe environmental protection cable that sprays that shocks resistance.
The utility model discloses a realize through following mode: the utility model provides a high safe environmental protection cable of resistant spraying shocks resistance, including conductive core, double-deck synthetic mica flame retardant coating, there is not steamed low cigarette flame retardant coating of pottery, there is not steamed low cigarette fire-retardant packing of steamed low cigarette, there is not steamed low cigarette fire-retardant inner sheath of pottery, no alkali glass fiber silk buffer layer, there is not steamed low cigarette band enhancement layer, there is not steamed low cigarette low heat fire-retardant oversheath, cable core peripheral space is filled up to its characterized in that there is steamed low cigarette fire-retardant inner sheath of pottery, the outside cladding does not have alkali glass fiber silk buffer layer, there is not steamed low cigarette band enhancement layer, the water-resistant spraying. The cable is characterized in that the halogen-free low-smoke low-heat-resistance flame-retardant outer sheath improves the flame-retardant and green environmental protection level of the cable.
The utility model has the advantages that: the impact-resistant spray-resistant high-safety environment-friendly cable has excellent fireproof, flame-retardant, mechanical impact-resistant and water spray-resistant performances, can be continuously electrified and normally operated for a plurality of hours under extremely severe fire environment conditions such as squeezing, pressing, smashing or water impact on the cable, ensures smoothness of electric power and information control, and strives for valuable time for personnel escape and fire rescue. Meanwhile, the fire-resistant and environment-friendly cigarette has the characteristics of no toxicity, low smoke and the like, so that the life and property safety is guaranteed to the maximum extent in a fire state.
Drawings
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a schematic cross-sectional view of the practice of the present invention.
In the figure, 1, a conductive wire core, 2, a double-layer synthetic mica fire-resistant layer, 3, a ceramic halogen-free low-smoke fire-resistant layer, 4, halogen-free low-smoke fire-resistant filling, 5, a ceramic halogen-free low-smoke fire-resistant inner sheath, 6, an alkali-free glass fiber buffer layer, 7, a halogen-free low-smoke wrapping band reinforced layer, 8, a halogen-free low-smoke low-heat fire-resistant outer sheath
Detailed Description
As shown in fig. 1, a shock-resistant spray-resistant high-safety environment-friendly cable comprises a conductive wire core 1, a double-layer synthetic mica flame-retardant layer 2, a ceramic halogen-free low-smoke flame-retardant layer 3, a halogen-free low-smoke flame-retardant filling 4, a ceramic halogen-free low-smoke flame-retardant inner sheath 5, an alkali-free glass fiber buffer layer 6, a halogen-free low-smoke wrapping reinforcement layer 7 and a halogen-free low-smoke low-heat flame-retardant outer sheath 8.
When in manufacturing, the conductive wire core 1 of the cable is formed by concentrically and hierarchically twisting or pressing a plurality of soft round copper single wires; the outside of the conductive wire core 1 is sequentially overlapped and wrapped with a double-layer synthetic mica fire-resistant layer 2 and a ceramic halogen-free low-smoke fire-resistant layer 3; when the cable core is twisted, the center is filled with halogen-free low-smoke flame-retardant filler 4; the ceramic halogen-free low-smoke fire-resistant inner sheath 5, the twisted alkali-free glass fiber buffer layer 6 and the wrapping 2 layers of the halogen-free low-smoke wrapping belt reinforcing layer 7 are wrapped outside the cable core in an extrusion mode, the outermost layer is wrapped with the halogen-free low-smoke low-heat fire-resistant outer sheath 8 in an extrusion mode, and identification marks are printed on the surface of the outer sheath in a spraying mode, so that the manufacturing is completed.
