Abstract

The utility model provides an ultra soft high flame retardancy fireproof cable and relates to the technical field of cable manufacture. The cable provided by the utility model comprises a cable core. Four high flame retardancy low smoke halogen-free wrapping layers, a copper band and copper wire braid dual shielding layer, a high temperature resistance fluorine plastic inner protection layer and an elastic body flame retardancy low smoke halogen-free polyolefin sheath layer are arranged outside the cable core in turn. The cable core comprises four wire cores. Each wire core respectively comprises an oxygen-free copper stranded conductor. Four refractory gold mica tape winding layers and a high temperature resistance fluorine plastic insulation layer are arranged outside each oxygen-free copper stranded conductor in turn. According to the utility model, the cable has good flame retardancy and refractory oxygen isolation physical properties; under the strong effect of an external fire source, secondary combustion of the surface of the cable is prevented; until the periphery materials of the cable core are all burnt and carbonized, the insulation layers of the cable conductors are not burnt due to heating; the conductors still work with power loads; and the cable is widely suitable for places with high fireproof requirements, is especially suitable for power transmission of a building and an airport, and has a high safety coefficient.

Description

Super soft high flame retardant fireproof cable
Technical field
The utility model relates to cables manufacturing technical field.
Background technology
Cable for can normal transmission in breaking out of fire situation electric energy, to win the quality time to safe escape and rescue be in time very important, due to the occasion, the application of New Building Materials, the longevity of service that use, often because aging circuit, electric conductivity, environmental-protecting performance and fire-retardant fireproof performance do not reach designing requirement breaking out of fire, cause heavy losses to the country and people's lives and properties.
Utility model content
The utility model object is for above problem, provide a kind of fire-retardant fireproof performance good, conduct electricity very well and the high flame retardant fireproof cable of environmental protection.
The utility model comprises cable core, in described cable core outside, sets gradually four floor height flame-retardant low-smoke halogen-free belting layers, copper strips and proof copper-wire braided double shield layer, thermostable fluorine plastics sheath and elastomer flame-retardant low-smoke halogen-free polyolefin jacket layer; Described cable core comprises four strand cores, and per share core comprises respectively oxygen-free copper bundle strand conductor, in oxygen-free copper bundle strand conductor outside, sets gradually four layers of refractory gold mica tape lapping layer and thermostable fluorine plastic insulating layer.
Diamagnetic interference performance of the utility model is strong; Thermostable fluorine plastics sheath and elastomer flame-retardant low-smoke halogen-free polyolefin jacket; high flame retardant has played a good protective effect from source; even also can guarantee electric energy normal transmission when breaking out of fire; for safe escape and rescue in time, win the quality time sound assurance is provided, and quality softness is convenient to crooked installation.The utlity model has fire-retardant and fireproof oxygen-separation physical property preferably, 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 being heated at all, conductor is still with electric loading to carry out work, is widely used in the higher place of fire protection requirement, is specially adapted to building airport delivery of electrical energy, coefficient of safety is high.
Four floor height flame-retardant low-smoke halogen-free belting layers described in the utility model are followed successively by the first high flame resistance, low smoke Halogen belting layer, the second high flame resistance, low smoke Halogen belting layer, third high flame-retardant low-smoke halogen-free belting layer and the 4th high flame resistance, low smoke Halogen belting layer from inside to outside.The wrapped protective layer of four floor height flame-retardant low-smoke halogen-free bands is set, can be because cable fire causes great personnel and property loss, and have do not melt, do not dissolve, the function such as Halogen, low toxicity.
Four layers of refractory gold mica tape lapping layer described in the utility model are followed successively by the first refractory gold mica tape lapping layer, the second refractory gold mica tape lapping layer, the 3rd refractory gold mica tape lapping layer and the 4th refractory gold mica tape lapping layer from inside to outside.Wrapped and the thermostable fluorine plastic insulation of four layers of gold mica tape is set, and insulation property are excellent, good stability, heatproof fire prevention.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises cable core, in cable core outside, sets gradually the first high flame resistance, low smoke Halogen belting layer 1, the second high flame resistance, low smoke Halogen belting layer 2, third high flame-retardant low-smoke halogen-free belting layer 3, the 4th high flame resistance, low smoke Halogen belting layer 4, copper strips and proof copper-wire braided double shield layer 5, thermostable fluorine plastics sheath 6 and elastomer flame-retardant low-smoke halogen-free polyolefin jacket layer 7; Cable core comprises four strand cores 8, per share core 8 comprises respectively oxygen-free copper bundle strand conductor 9, in oxygen-free copper bundle strand conductor 9 outsides, sets gradually the first refractory gold mica tape lapping layer 10, the second refractory gold mica tape lapping layer 11, the 3rd refractory gold mica tape lapping layer 12, the 4th refractory gold mica tape lapping layer 13 and thermostable fluorine plastic insulating layer 14.
