Abstract
The invention relates to a cable reinforcing mandrel for a power transmission cable. The cable reinforcing mandrel comprises an inner electroconductive layer and an outer insulating layer, and is characterized in that a winding layer is arranged between the inner electroconductive layer and the outer insulating layer. According to the technical scheme adopted in the invention, the winding layer is added, therefore, the cable reinforcing mandrel for the power transmission cable has the advantages of increased resistance to destructiveness in a radial direction, and simultaneously enhanced flattening, bending and other mechanical properties.
Description
Technical field
The present invention relates to a kind of cable and strengthen plug, especially a kind of power transmission cable is with cable strengthening core rod.
Background technology
Carbon fiber composite core wire is the new product of the traditional steel core aluminium hinge lead of the desirable replacement of present bulk of worldwide electricity power transmission and transformation system, aluminium Baogang lead, aluminium alloy conductor.The employed overwhelming majority of China power transmission and distribution system still is a steel core aluminium hinge line, and its shortcoming is than great, and perishable, operating temperature is low, forms sag etc. easily.Compare with conventional wires, carbon fiber composite core wire has the following advantages: the one, and in light weight; The 2nd, intensity is high; The 3rd, the magnetic loss and the thermal effect that do not exist wire material to cause reduce transmission loss; The 4th, reduce the above sag of twice; The 5th, operating temperature can significantly improve; The 6th, thermal coefficient of expansion is low; The 7th, corrosion-resistant etc.These advantages can solve the problem that the conventional aluminum twisted wire exists, and therefore get more and more people's extensive concerning.Common in the market power transmission cable is strengthened plug with composite material cable, is made up of inside and outside two parts, and wherein internal layer is a high-performance continuous fibre enhancement resin based composites; Skin is the high temperature resistant thermosetting plastics, plays insulation protection.Its shortcoming is radially a little less than the survivability, simultaneously poor mechanical property such as plug flattening, bending.
Summary of the invention
To above-mentioned existing problems, the present invention provides a kind of power transmission cable with cable strengthening core rod, through the change of structure, improves its radially survivability, improves mechanical properties such as its flattening, bending simultaneously.
In order to reach above purpose, the present invention takes following technical scheme, and a kind of power transmission cable comprises internal layer conductive layer and outer insulation with cable strengthening core rod, it is characterized in that: also have one deck winding layer between said internal layer conductive layer and the outer insulation.
Because the present invention has taked above technical scheme, has the following advantages:,, improve mechanical properties such as its flattening, bending simultaneously so can improve its radially survivability owing to increased winding layer.
Description of drawings
Fig. 1 is a structural representation of the present invention
The 1st, conductive layer 2 is that winding layer 3 is insulating barriers.
Embodiment
Below in conjunction with embodiment the present invention is described further.
Embodiment one
A kind of power transmission cable comprises internal layer conductive layer and outer insulation with cable strengthening core rod, it is characterized in that: also have one deck winding layer between said internal layer conductive layer and the outer insulation.
Embodiment two
With cable strengthening core rod, its difference is with a kind of power transmission cable of embodiment one: said winding layer have two-layer or two-layer more than.
Embodiment three
A kind of power transmission cable with embodiment one is excellent with the cable strengthening core, and its difference is: the winding direction of said winding layer is clockwise, counterclockwise adjacent setting, and promptly one is that one is counterclockwise clockwise.
Except that the foregoing description, the present invention can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
Claims (3)
1. a power transmission cable comprises internal layer conductive layer and outer insulation with cable strengthening core rod, it is characterized in that: also have one deck winding layer between said internal layer conductive layer and the outer insulation.
