Abstract
The invention discloses an armored power cable for high speed railway which includes the conducting core. The conducting core has three stranded lines. The conducting core is jacketed by insulation layer which is also protected by the inner sheath. The inner sheath has fire-resistant layer over it. The insulation layer is provided with reinforcement which has more than 1 string. The reinforcement resembles a shape of radiating outward. The filler is provided between the insulation layer and the inner sheath. The filler encapsulates the reinforcement and the insulation layer. The single rotary strand outside of the fire-resistant layer is provided with steel wire armor which uses the galvanized round steel wire. The outer sheath is also provided outside of the steel wire armor; the armored power cable for high speed railway can effectively enhances the mechanical property and electric conductivity of the cable with high tensile strength and anti-resistivity. The armored cable improves the anti-corrosion properties, in particular can prevent the damages caused by the underground machinery construction or bites of subterranean rodents.
Description
Technical field
Present invention relates particularly to a kind of high ferro armoured power cable.
Background technology
Electric wire refers to the wire rod for electric power, communication and associated transport purposes, is to convey electric energy, transmission information and enter
Row electromagnetic conversion and the various motors of manufacture, electrical equipment, instrument institute indispensable basis equipment.Our times resource is increasingly tight
, the material that electric wire is used is also extremely strict, for the electronic material for lead frame, terminal, connector etc.,
Fundamental characteristics as product is it is desirable to high intensity and high electric conductivity or heat conductivity have both.
Continuous improvement electric energy being needed with power consumer, the big electrical appliance of various power consumption is widely used,
Due to the big electrical appliance of power consumption at work, often require that improving the power transmission cable of electric power for it needs to have larger excessively stream
Ability and bearing capacity, therefore currently common processing method is to increase the needs to meet use for the line footpath of service cable, but
With the increase of cable diameter, also result in that cable cost is higher, collection skin effect also easily in the larger and cable itself of deadweight simultaneously
Should, thus it is higher to result in such erecting cable, use cost, and limited efficacy of powering is it is impossible to effectively meet power consumer
Using needs, meanwhile, when constructing in road trimming or again, easily suffer from the ground such as destruction or the mouse of the mechanical external forces such as excavator
The destruction of lower animal, when carrying high current, high-tension work, external insulation is susceptible to deform, very existing cable
To puncturing, insulating properties are affected, and the heart yearn that may affect in power transmission effect, and its cable after working long hours is most
Number is copper wires, and due to the design using copper, its price is costly higher with density, and the surface of copper easily causes oxygen for a long time
Change, cause thermoplastic property difference and low intensity, cause great difficulty, therefore urgently therefore to power construction and regular maintenance
Need to develop a kind of novel cable to meet actually used needs.
Content of the invention
For overcoming the problems of the prior art, the invention provides a kind of mechanicalness that can effectively improve cable, electricity
The property led, its tensile strength, anti-resistivity are high, improve corrosion resistance, are particularly prevented from the machinery during mechanical execution of underground and break
The high ferro armoured power cable of the bad destruction with subteranean animal.
The technology of employing and method in order to solve the problems, such as the above-mentioned present invention are as follows:
A kind of high ferro armoured power cable, includes conductive core material, and described conductive core material is provided with three and sets in mutually stranded
Put, described conductive core material is wrapped with insulating barrier, described insulating barrier is externally provided with inner sheath, described inner sheath is externally provided with flame retardant coating,
Described insulating barrier is provided with reinforcement, and described reinforcement is provided with one or more, and described reinforcement is in external radiation on the insulating layer
Shape is arranged, and is filled with filler, described filler wrapped stiffener and insulating barrier, described insulating barrier between described insulating barrier and inner sheath
Arrange for integral type with reinforcement, described flame retardant coating outer sub-thread rotation strand has steel wire armor layer, and described steel wire armor layer adopts zinc-plated
Round steel wire, is additionally provided with oversheath outside described steel wire armor layer.
Further, described conductive core material is made up of the raw material of following weight portion: ferrum 0.01-0.1 part, silicon 0.03-0.05
Part, nickel 0.1-0.3 part, chromium 0.1-0.3 part, zirconium 0.1-0.3 part, stannum 0.05-0.08 part, zinc 0.0001-0.001 part, gallium

2-4 part, cerium 1-3 part, vanadium 1-3 part and tungsten 1-3 part.
Further, described inner sheath is fluorine material sheath.
Further, described oversheath is low smoke and zero halogen sheath.
Further, the thickness of described flame retardant coating is 0.2-0.6mm.
Further, described flame retardant coating is made using electro-insulating rubber.
Further, described firming agent is modified fatty amine or modified aliphatic cyclic amine, and described bonding agent is epoxy resin
It is cementing agent, described toughener is glass fibre.
Further, described conductive core material is made up of the raw material of following weight portion: 0.01 part of ferrum, 0.03 part of silicon, manganese 0.5
Part, 0.05 part of titanium, 0.03 part of niobium, 0.3 part of vanadium, 0.003 part of boron, 0.1 part of nickel, 0.1 part of chromium, 0.1 part of zirconium, 0.05 part of stannum, zinc
