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 conductive layer; Skin is the high temperature resistant thermosetting plastic insulating layer, plays insulation protection.Its production technology is for mainly comprising baking operation, twisting operation, impregnation operation, coating curing process and winding process; It coats curing process for to coat cladding material through stranded (winding) mode; Solidify through solidification equipment then; Its shortcoming is that covering property is poor, low, the poor toughness of the heat resisting temperature of manufactured goods.
Summary of the invention
To above-mentioned existing problems, the present invention provides a kind of aerial condutor with composite material cable strengthening core rod production process, through the improvement of production technology, makes it have good covering property, improves its radially mechanical property such as survivability and flattening, bending simultaneously.
In order to reach above purpose; The present invention takes following technical scheme; A kind of aerial condutor is with composite material cable strengthening core rod production process, and cable is strengthened plug by internal layer and outer the composition, and internal layer is a conductive layer; Skin is an insulating barrier; Its production technology comprises baking operation, twisting operation, impregnation operation, coats curing process and winding process, and it is characterized in that: said coating curing process comprises winding working procedure, precuring operation and pultrusion curing process, and said winding working procedure is for increasing one deck winding layer through getting into wind behind the plastic squeeze roller strengthen plug through the cable that the impregnation operation obtains outside cable is strengthened the plug internal layer; Said precuring operation is for introduce preforming tool precuring moulding to the cable reinforcement plug and the outer layer insulation material that wind together; Said pultrusion curing process is to strengthen plug to the cable of precuring moulding to introduce pultrusion die extruding curing.
Because the present invention has taked above technical scheme; Have the following advantages: through coating curing process is winding working procedure, precuring operation and pultrusion curing process; Make it on the internal layer conductive layer, increase by a winding layer; Simultaneously have good covering property (smooth surface interior solid) again, improve its radially mechanical property such as survivability and flattening, bending.
