Abstract

The utility model discloses a heatproof and fireproof double shielding reinforcement cable, comprising main wire cores, control wire cores, a filler, a belting layer, an inner shielding layer, a fluororubber insulating layer, an outer shielding layer, and a low smoke halogen-free sleeve. Four sets of main wire cores and two sets of control wire cores are provided, and are all disposed in the belting layer. Two sets of the main wire cores are disposed between the two sets of the control wire cores. The outer shielding layer and the low smoke halogen-free sleeve are coated by a galvanizing steel wire braiding metal layer. The heatproof and fireproof double shielding reinforcement cable is advantageous in that service lifetime is long and conductivity is good; insulating property is good and interference resistance is strong; the cable is widely applied in fields of petrochemical industry and metallurgy manufacturing; the wire cores are firm and good in heat resistance, flame retardation and antioxidation; the cable has low smoke, no halogen and protects environment.

Description

A kind of heat resistant fire-proof double shield is strengthened cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of heat resistant fire-proof double shield and strengthens 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.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model be 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 utility model 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 utlity model has in sum following beneficial effect: 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.

Embodiment

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 utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
