Abstract
The utility model is a low-smoke and halogen-free cable, which has a copper-clad aluminum core, a radiation crosslinked insulating layer and an oxygen barrier. The utility model consists of a copper core or a copper-clad aluminum cable core 1, an insulating layer 2, filler 3 and a sheath 5. The utility model is characterized in that a oxygen insulation fire-retardant layer 4 is arranged between the insulating layer 2 and the sheath 5; wherein, the material of the oxygen insulation fire-retardant layer is NH1G. The insulating layer is made of radiation crosslinked polyethylene material and the sheath is made of low-smoke and halogen-free polyolefin material NH1H-5L. The utility model enables the smoke density to be reduced greatly and the cable to supply power more than 180 minutes under the combustion condition from 750 DEG C to 1000 DEG C with little smoke and no halogen.
Description
Technical field
The utility model relates to power cable.
Background technology
The power cable of environmental protection fire control type more and more comes into one's own in the application in modern industry and civilian power cable field, and how making cable reach cable with lower cost can be fire-retardant in hot environment, few smog, do not discharge the popular research topic that halogen gas is present power cable industry.And the cable material that generally uses, its insulating barrier and restrictive coating heatproof temperature are low, generally only can reach 70 ℃, surpass burning or a large amount of smog that the heatproof temperature might cause insulating barrier and restrictive coating, especially a large amount of smog and halogen gas are the main causes that the personnel that cause suffocate.Thereby may cause electric power system fault and personal, financial heavy losses.
Summary of the invention
The purpose of this utility model provides that a kind of production cost is low, environment friendly flame-retardant copper-covered aluminum-core, cross-linking radiation insulating barrier, oxygen barrier layer, low-smoke halogen-free cable.
Described copper-covered aluminum-core, cross-linking radiation insulating barrier, oxygen barrier layer, low-smoke halogen-free cable, form by copper core or copper-covered aluminum-core 1, insulating barrier 2, inserts 3 and restrictive coating 5, it is characterized in that: between insulating barrier 2 and restrictive coating 5, also have one deck oxygen barrier flame-retardant layer 4, oxygen barrier flame-retardant layer to adopt low-smoke non-halogen flame-retardant oxygen barrier material NH1G.Adopt the IXPE material as insulating barrier.Adopt low-smoke halogen-free polyolefin material NH1H-5L as restrictive coating.
The utility model has the advantages that: the insulating barrier heatproof significantly improves, reach more than 105 ℃, the oxygen barrier flame-retardant layer further improves the working temperature of cable, strengthen fire resistance, improved the ampacity of conductor simultaneously, the low smoke and zero halogen sheath makes smoke density significantly reduce, make cable under 750 ℃～1000 ℃ burning conditions, can guarantee that still normal power supply more than 180 minutes, only has smog seldom, not discharge halogen gas.
Description of drawings
Fig. 1 is the utility model cross-sectional structure schematic diagram.
Among the figure: 1-copper core or copper-covered aluminum-core, 2-insulating barrier, 3-inserts, 4-oxygen barrier flame-retardant layer, 5-restrictive coating.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: general power cable core can have single core to 5 core etc., and schematic diagram is the example explanation with 4 cores.Described copper-covered aluminum-core, IXPE insulation, polyolefin jacket low-smoke halogen-free cable, form by copper core or copper-covered aluminum-core 1, insulating barrier 2, inserts 3 and restrictive coating 5, it is characterized in that: also have one deck oxygen barrier flame-retardant layer 4 between insulating barrier 2 and restrictive coating 5, oxygen barrier flame-retardant layer material is NH1G.Adopt the IXPE material as insulating barrier 2.Adopt low-smoke halogen-free polyolefin material NH1H-5L as restrictive coating 5.
Adopt said structure cable environmental protection fire-fighting performance greatly to improve, specifically, general polyethylene layer heatproof can arrive 70 ℃, and this can rise to 90 ℃ to adopt crosslinked polyethylene, and uses the IXPE material, and heatproof can reach more than 105 ℃.When the insulating barrier heatproof improves, increase the oxygen barrier flame-retardant layer, oxygen index reaches 45%.Make under internal high temperature or outside naked light or the hot environment, strengthen the oxygen barrier fire resistance, heat insulation, oxygen barrier, press down cigarette, improved working temperature, strengthened dielectric strength.And through experiment, when cable raise in temperature, electric conductivity can improve.Make the whole synthesis performance of cable greatly strengthen.Add polyolefin low smoke and zero halogen sheath, low smog does not produce poisonous halogen gas under hot environment.Smoke density dropped to below 90 when naked light was arranged, below the flames of anger to 180.The cable that adopts said structure still can guarantee normal power supply more than 180 minutes under 750 ℃～1000 ℃ burning conditions, only produce smog seldom and do not discharge halogen gas.After testing, every index all meets the GA306 of Ministry of Public Security standard-required.
Because the utlity model has good environmental protection fire-fighting characteristic, and cheap, every performance all has significantly raising, makes it to have the very big market competitiveness.
