Description
Technical field
Present invention relates particularly to a kind of armoured power cables.
Background technology
Electric wire refers to the wire rod for electric power, communication and associated transport purposes, be conveying electric energy, transmit information and into
Row electromagnetic conversion and the various motors of manufacture, electric appliance, the indispensable basic equipment of instrument institute.Our times resource is increasingly tight
, it is also extremely stringent to material used in electric wire, for the electronic material for lead frame, terminal, connector etc.,
Fundamental characteristics as product, it is desirable that high intensity and high electric conductivity or thermal conductivity have both.
With the continuous improvement that power consumer needs electric energy, the big electrical appliance of various power consumption is widely used,
At work due to the big electrical appliance of power consumption, often require that improving the power transmission cable of electric power for it needs to have larger overcurrent
Ability and bearing capacity, thus current common processing method be increase the line footpath of service cable to meet the needs used, but
With the increase of cable diameter, at the same also result in cable cost it is higher, dead weight larger and cable itself also easily occur collection skin effect
It answers, so as to cause such erecting cable, higher operating costs, and limited efficacy of powering, it cannot effectively meet power consumer
Using needs, meanwhile, the ground such as destruction or mouse when rebuilding in road or constructing again easily by mechanical external forces such as excavators
The destruction of lower animal, when carrying the work of high current, high voltage, external insulation easily deforms existing cable, very
To breakdown, insulation performance is affected, and power transmission effect may be influenced after working long hours, and the core wire in its cable is most
Number is copper wires, and due to the design using copper, price is costly higher with density, and the surface of copper be easy to cause oxygen for a long time
Change, causes thermoplastic property difference and intensity is low, therefore had caused great difficulties to power construction and daily maintenance, therefore is urgent
Need to develop a kind of novel cable to meet the needs of actual use.
Invention content
To overcome the problems of the prior art, the present invention provides a kind of mechanicalness that can effectively improve cable, electricity
The property led, tensile strength, anti-resistivity are high, improve corrosion resistance, can especially prevent the machinery when mechanical execution of underground broken
The armoured power cable of bad and subteranean animal destruction.
In order to which the technology and method that solve the problem above-mentioned use of the invention are as follows：
A kind of armoured power cable includes conductive core material, is set there are three the conductive core material is set and in mutually twisted
It sets, the conductive core material is wrapped with insulating layer, and the insulating layer is externally provided with inner sheath, and the inner sheath is externally provided with flame retardant coating,
The insulating layer is equipped with reinforcing rib, and the reinforcing rib is equipped with one or more, and the reinforcing rib is in external radiation on the insulating layer
Shape is arranged, and filler is filled between the insulating layer and inner sheath, the filler is interposed between reinforcing rib and inner sheath, described to fill out
Expect that wrapped stiffener and insulating layer, the insulating layer and reinforcing rib are arranged for integral type, the outer sub-thread rotation of the flame retardant coating, which twists, steel
Silk armor, the steel wire armor layer use galvanized steel bar silk, oversheath are additionally provided with outside the steel wire armor layer.
