Abstract

The invention discloses a special cable for slag cars. The cable mainly comprises seven copper-conductor cores, a tin-plated nickel strip armor layer, an ethylene propylene rubber insulating layer, a polychloroprene sheath layer, a polyester fiber layer, a low-smoke halogen-free polyethylene sheath layer and sixteen tin-plated copper conductors. The seven copper-conductor cores are stranded together and covered with the tin-plated nickel strip armor layer, the tin-plated nickel strip armor layer is covered with the ethylene propylene rubber insulating layer, and the sixteen tin-plated copper conductors are extruded between the polychloroprene sheath layer and the polyester fiber layer. The special cable for the slag cars has special properties of wear resistance, flame resistance, molten steel splashing protection and the like. According to the arrangement, service life of the cable is prolonged, layout space of the cable is reduced effectively, and the cable has high tensile resistance.

Description

A kind of slag car private cable

Technical field

The invention belongs to field of cables, particularly relate to a kind of slag car private cable.

Background technology

As everyone knows, steel-making be exactly with the pig iron, steel scrap, slag making materials etc. for raw material, by heat fused, slag making, dephosphorization, oxidation and decarbonization and degasification, reduce deoxidization desulfuration, remove the smelting process that impurity produces steel.And a kind of special installation must be used in whole smelting process, i.e. the slag car.The running environment of the slag car is severe, except itself frequently moves, its periphery is in high-temperature region and often has molten steel to splash, this just makes matching used cable often need to do high-speed mobile, bear larger pulling force and bend and be in high-temperature area, traditional cable uses very short a period of time just to there will be quality problems usually, as core fracture, sheath season crackings etc., directly affect the production efficiency of steel mill.For this reason, need high performance slag car cable to match with it.

Summary of the invention

In order to overcome the defect of above-mentioned prior art, the invention provides a kind of slag car private cable.

The present invention takes following technical scheme to realize: a kind of slag car private cable, it mainly comprises copper conductor cable core, zinc-plated nickel strap armour, ethylene propylene rubber insulated layer, chloroprene rubber sheath layer, layer of polyester fiber, low smoke and zero halogen pe sheath layer and tinned copper conductor, described copper conductor cable core is set to seven groups, often organize copper conductor cable core and be set to three layers, the central core often organizing copper conductor cable core is set to a steel band tensile cord, outer wrapping one deck nonmagnetic metal armour of steel band tensile cord and outermost layer are copper strips armouring pe sheath layer, two groups of copper conductor cores are extruded with between described nonmagnetic metal armour and copper strips armouring pe sheath layer, the zinc-plated nickel strap armour of outer wrapping one deck that seven groups of copper conductor cable cores twist together, the ethylene propylene rubber insulated layer of outer wrapping one deck of described zinc-plated nickel strap armour, described tinned copper conductor is set to 16, be extruded between chloroprene rubber sheath layer and layer of polyester fiber.

The present invention has following beneficial effect in sum: the present invention has wear-resisting, fire-retardant, anti-molten steel and to splash the property such as to burn, the effective useful life extending cable, simultaneously effectively reduces cable installation space, and particularly pull resistance is strong.

Accompanying drawing explanation

Fig. 1 is cross-sectional structure schematic diagram of the present invention;

Wherein: 1, copper conductor cable core; 11, steel band tensile cord; 12, nonmagnetic metal armour; 13, copper strips armouring pe sheath layer; 14, copper conductor core; 2, zinc-plated nickel strap armour; 3, ethylene propylene rubber insulated layer; 4, chloroprene rubber sheath layer; 5, layer of polyester fiber; 6, low smoke and zero halogen pe sheath layer; 7, tinned copper conductor.

Embodiment

As shown in Figure 1, a kind of slag car private cable, it mainly comprises copper conductor cable core 1, zinc-plated nickel strap armour 2, ethylene propylene rubber insulated layer 3, chloroprene rubber sheath layer 4, layer of polyester fiber 5, low smoke and zero halogen pe sheath layer 6 and tinned copper conductor 7, described copper conductor cable core 1 is set to seven groups, often organize copper conductor cable core 1 and be set to three layers, the central core often organizing copper conductor cable core 1 is set to a steel band tensile cord 11, outer wrapping one deck nonmagnetic metal armour 12 of steel band tensile cord 11 and outermost layer are copper strips armouring pe sheath layer 13, two groups of copper conductor cores 14 are extruded with between described nonmagnetic metal armour 12 and copper strips armouring pe sheath layer 13, the zinc-plated nickel strap armour 2 of outer wrapping one deck that seven groups of copper conductor cable cores 1 twist together, the ethylene propylene rubber insulated layer 3 of outer wrapping one deck of described zinc-plated nickel strap armour 2, described tinned copper conductor 7 is set to 16, be extruded between chloroprene rubber sheath layer 4 and layer of polyester fiber 5.

Embodiment: the ethylene propylene rubber insulated layer 3 of outer wrapping one deck of described zinc-plated nickel strap armour 2, improves the insulation property of this cable; The central core often organizing copper conductor cable core 1 is set to a steel band tensile cord 11, to improve the tensile property of this cable.

Further, steel band tensile cord 11 cross section is less than 18 mm ², be greater than 12 mm ²; Each root copper conductor makes by copper wire is stranded, and copper conductor cross section is less than 8 mm ², be greater than 6 mm ²; Tinned copper conductor 7 makes by tinned copper wire is stranded, and tinned copper conductor cross section is less than 16 mm ², be greater than 12 mm ²; Outermost layer is low smoke and zero halogen pe sheath layer 6, and thickness is the value range between 0.8cm to 1.2cm.

Further, the permission bending radius of this cable is 8 times of the outside diameter of cable.

The above is the embodiment of the present invention, therefore all equivalences done according to structure, feature and the principle described in the present patent application scope change or modify, and are included in patent claim of the present invention.
