Abstract
Provided is a rat-and-ant proof low smoke zero halogen fireproof computer cable, relating to the computer cable technology field. The computer cable of the utility model is characterized in that: a polyester strap general lapping layer is arranged outside the cores; polypropylene stuffing is arranged between the cores inside the polyester strap general lapping layer; a copper plastic composite general shielding layer, an oxygen-insulation flame retardation belting layer, and a rat-and-ant proof low smoke zero halogen over-sheath are sequentially arranged outside the polyester strap general lapping layer; and an oxygen-free copper filament drainage wire is arranged between the polyester strap general lapping layer and the copper plastic composite general shielding layer along the cable length direction. The computer cable of the utility model features rat-and-ant proof, sound shielding property and flame retardation performance, low smoke amid combustion, and no corrosion gas escape. The computer cable can be applied to the computer control center and high-rise in nuclear power stations, subways, stations, etc. The computer cable can also be applied to military facility, petroleum platform, and other places with concentrative people and low air density.
Description
Technical field
The utility model relates to fiery computer cable technical field.
Background technology
Along with a large amount of of automatic control popularize; Computer is as the core of signal controlling; Because the accident like fire, mouse ant etc. takes place in place in that some personnel concentrate, atmospheric density is low easily; In case these incidents take place, with the transmission that directly jeopardizes signal, so the performance of a little types of regional computer cables of necessary raising.
Summary of the invention
The utility model purpose is to propose a kind of have protection against rodents ant, computer cable that fire line is high.
The utility model comprises at least two group cores; Put the total lapping layer of polyester belt at the core peripheral hardware; Polypropylene is set between the core in the total lapping layer of said polyester belt fills material; Outside the total lapping layer of polyester belt, set gradually copper and mould compound total screen, the fire-retardant belting layer of oxygen barrier and protection against rodents ant low smoke and zero halogen external sheath layer, and mould between compound total screen at the total lapping layer of polyester belt and copper and the copper free wire drainage thread to be set along said cable length direction.
The utility model is respectively organized core and is comprised two insulated leads; Outside two insulated leads, lapping layer in the polyester belt is set; Compound copper-plastics band grouping screen is set outside the lapping layer in said polyester belt, in said polyester belt, along said core length direction the copper free wire drainage thread is set between lapping layer and the said compound copper-plastics band grouping screen.
The every insulated lead of the utility model comprises stranded copper free wire conductor, outside said stranded copper free wire conductor, sets gradually mica tape lapping layer and crosslinked polyetylene insulated layer respectively.
The utility model protection against rodents ant electric cable material with low smoke and halogen free is as the oversheath of cable, and this cable has good protection against rodents ant property and shielding properties, and fire resistance is good; And smog is very few during burning; Non-corrosiveness gas is overflowed, and the copper free wire conductor has pliability functional characteristics preferably, and the utility model can be widely used in computer controlling center, the skyscraper building of occasions such as nuclear power station, subway, station; Important military installations, oil platform, and the place that personnel concentrate, atmospheric density is low.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
As shown in Figure 1, every insulated lead 1 is provided with seven gangs of stranded copper free wire conductor 1-1, outside stranded copper free wire conductor 1-1, sets gradually mica tape lapping layer 1-2 and crosslinked polyetylene insulated layer 1-3 respectively.
Every core 2 is provided with two insulated leads 1; Lapping layer 2-1 in the polyester belt is set outside two insulated leads 1; Compound copper-plastics band grouping screen 2-2 is set outside the lapping layer 2-1 in polyester belt, and the length direction of core 2 along the line is provided with a copper free wire drainage thread 2-3 between lapping layer 2-1 and the compound copper-plastics band grouping screen 2-2 in polyester belt.
The total lapping layer 3 of polyester belt is set outside three groups of cores 2; Polypropylene is set between the core 2 in the total lapping layer 3 of polyester belt fills material 4; Outside the total lapping layer 3 of polyester belt, set gradually copper and mould compound total screen 5, the fire-retardant belting layer 6 of oxygen barrier and protection against rodents ant low smoke and zero halogen external sheath layer 7, and mould between compound total screen 5 at the total lapping layer 3 of polyester belt and copper and a copper free wire drainage thread 8 to be set along the cable length direction.
