Abstract
The invention discloses a heat resistant fireproof double-shielding reinforced cable which comprises main cable cores, control cable cores, fillers, a wrapping tape layer, an inner shielding layer, a fluororubber insulating layer, an outer shielding layer and a low-smoke zero-halogen jacket. The number of the main cable cores is four, the number of the control cable cores is two, the main cable cores and the control cable cores are all wrapped by the wrapping taper layer in an extruded mode, the two control cable cores are separated through two main cable cores, and a zinc-coated wire braided metal layer is wrapped between the outer shielding layer and the low-smoke zero-halogen jacket. The heat resistant fireproof double-shielding reinforced cable is long in service life, good in electric conductivity, good in insulation and high in interference resistance, and is widely applied to the fields such as the petrochemical industry and metallurgy manufacturing; meanwhile, the heat resistant fireproof double-shielding reinforced cable is firm in cable core, heat resistant, flame resistant, oxidation resistant, low in smoke, free of halogen, environmentally friendly and the like.
Description
Technical field
The present invention relates to field of cables, relate in particular to a kind of heat resistant fire-proof double shield and strengthen cable.
Background technology
At present, all very high to the each side quality requirement of cable, because very important of the fail safe of cable, otherwise will cause great potential safety hazard.General cable shield is not strong, and fire protecting performance is inadequate, once burning will discharge a large amount of dense smoke and toxic gas, life threatening and property.The actual service condition that only meets cable, just can better ensure the fail safe of cable.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one have fire-retardant, high temperature resistant, fireproofing corrosion resistant erosion, strong interference immunity, the heat resistant fire-proof double shield of low smoke and zero halogen environmental protection is strengthened cable.
The present invention takes following technical scheme to realize: a kind of heat resistant fire-proof double shield is strengthened cable, it comprises master core, controls core, filler, belting layer, internal shield, fluorubber insulating barrier, outer shielding layer and low smoke and zero halogen sheath, described master core has four groups, described control core is two groups, all be extruded in described belting layer inside, described in two groups, control the master core described in two groups of being separated by between core, between described outer shielding layer and described low smoke and zero halogen sheath, wrap up zinc-coated wire braided metal layer.
Described control core is made up of the stranded cable core of the outer coppered wire of zinc-plated aluminium wire and the tin plated steel wire armour being wrapped in outside cable core.
Described master core is made up of nickel-clad copper conductor thread core, fluorubber insulating barrier and the copper wire heating wire that is extruded in fluorubber insulating barrier inside, and described copper wire heating wire is two.
Described master core circumference is tangent with described filler, described internal shield respectively.
The present invention has following beneficial effect in sum: this cable long service life, of many uses, good conductivity, have good insulating properties, strong interference immunity, is widely used in the field such as petrochemical industry, metallurgical manufacture, core is firm, heat-proof combustion-resistant, non-oxidizability is strong, also has the characteristics such as low smoke and zero halogen environmental protection simultaneously.

As shown in Figure 1, a kind of heat resistant fire-proof double shield is strengthened cable, it comprises master core 1, controls core 2, filler 3, belting layer 4, internal shield 5, insulating barrier 6, outer shielding layer 7 and low smoke and zero halogen sheath 9, described master core 1 is four groups, described control core 2 is two groups, all be extruded in described belting layer 4 inside, described in two groups, control the master core 1 described in two groups of being separated by between core 2, between described outer shielding layer 7 and described low smoke and zero halogen sheath 9, wrap up zinc-coated wire braided metal layer 8.
Described control core 2 is made up of the stranded cable core of the outer coppered wire of zinc-plated aluminium wire and the tin plated steel wire armour being wrapped in outside cable core.
Described master core 1 is made up of nickel-clad copper conductor thread core 1a, fluorubber insulating barrier 1c and the copper wire heating wire 1b that is extruded in fluorubber insulating barrier 1c inside, and described copper wire heating wire 1b is two.
Described master core 1 circumference is tangent with described filler 3, described internal shield 5 respectively.
The permission bending radius of this cable is the outside diameter of cable 8 times; Can stand to exchange 50HZ, 3.5Kv/5min voltage and not breakdown.
The above is the embodiment of the present invention, and the equivalence of doing according to structure, feature and principle described in the present patent application scope therefore all changes or modifies, and is included in patent claim of the present invention.
