Abstract
The utility model relates to an energy-saving halogen-free cable for the fire prevention of an intelligent building, and the energy-saving halogen-free cable belongs to the technical field of electric power controlling and fire resisting. The core of the energy-saving halogen-free cable is composed of stranded high-quality oxygen-free copper conductors, winded double-layer fire-resistant mica tapes and high-temperature resisting fluoroplastic insulating layers; cable wrapping tapes are externally provided with woven double-layer copper strip or copper wire shielding layers; the woven double-layer copper strip or copper wire shielding layers are externally provided with high flame-retardant fiberglass tapes; and the high flame-retardant fiberglass tapes are externally provided with flame-retardant halogen-free low-smoke polyolefin sheathes. The energy-saving halogen-free cable has good physical properties of flame retardance, fire resistance and oxygen insulation, can ensure the normal electric power transmission in case of fire disaster and powerfully guarantees thesafe escape and timely rescue.
Description
Technical field
The utility model relates to electric power control and fire-resistant technical field.
Background technology
Cable for can normal transmission under the breaking out of fire situation electric energy, to win the quality time for safe escape and rescue in time be very important, because occasion, the application of New Building Materials, the operating time of using are long, often because of aging circuit, electric conductivity, environmental-protecting performance and fire-retardant fireproof performance do not reach the designing requirement breaking out of fire, cause heavy losses for the country and people's lives and properties.
The utility model content
The purpose of this utility model is to design a kind of high flame retardant, oxygen barrier, fire-resistant, can both the normal transmission electric energy under the breaking out of fire situation, give a kind of fire prevention that safe escape and rescue in time win the quality time with fire-retardant Halogen cable.
The technical solution of the utility model is: the utility model comprises wrapped cable core in band, and band sets gradually screen, the wrapped protective layer of high flame retardant glass fibre belt, flame-retardant low-smoke halogen-free polyolefin jacket outward from inside to outside.
Described cable core comprises some cores, and the wrapped and thermostable fluorine plastic insulating layer of stranded, the double-deck anti-mica tape of high-quality oxygen-free cupreous that core is provided with by from-inner-to-outer is formed.
Described screen is double-deck copper strips or copper wire braid shielded.
The utlity model has fire-retardant preferably and fire-resistant oxygen barrier physical property, externally under the strong effect of burning things which may cause a fire disaster, cable surface can not prolong combustion, till the whole calcination charings of cable core peripheral material, but it is burnt that the insulating barrier of cable conductor can not sent out because of being heated at all, the still charged load of conductor carries out work, is widely used in occasions with higher fireproof requirements, is specially adapted to Ground Connection in Intelligent Building electric energy transmitting, coefficient of safety height.Wrapped and the thermostable fluorine plastic insulation of double-deck mica tape is set in the cable, and insulation property are excellent, good stability, heatproof are fire-resistant; The wrapped protective layer of high flame retardant glass fibre belt is set, can be because of cable fire does not cause great personnel and property loss, and have do not melt, do not dissolve, function such as Halogen, low toxicity; The flame-retardant low-smoke halogen-free polyolefin jacket is set, and high flame retardant has played a good protective effect from the source, even also can guarantee the electric energy normal transmission when breaking out of fire, wins the quality time for safe escape and rescue in time sound assurance is provided.
Description of drawings
Fig. 1 is the utility model structural representation
1-1 is that the oxygen-free copper conductor is stranded among the figure, 1-2 is that double-deck fire-resistant isinglass belt is wrapped, 1-3 is the thermostable fluorine plastic insulating layer, 2 be the halogen-free polyolefin protective sleeve for high flame retardant glass fibre belt bag protective layer, 5 for screen, 4 for band, 3.
Embodiment
As shown in Figure 1: core 1 is made up of the stranded 1-1 of high-quality oxygen-free copper conductor, the wrapped 1-2 of double-deck fire-resistant isinglass belt and thermostable fluorine plastic insulating layer 1-3; in by band 2 the cable core stranding being wrapped in; stranding band 2 outer copper strips and the copper wire braiding double layer screen layers 3 of being provided with; the wrapped protective layer 4 of high flame retardant glass fibre belt is set outside screen 3, flame-retardant low-smoke halogen-free polyolefin jacket 5 is set outside protective layer 4.
Claims (3)
1. the intelligent building fire prevention is characterized in that with energy-saving Halogen cable comprise wrapped cable core in band, band sets gradually screen, the wrapped protective layer of high flame retardant glass fibre belt, flame-retardant low-smoke halogen-free polyolefin jacket outward from inside to outside.
