First, the power cord copper, aluminum monofilament drawing. Power cord commonly used copper, aluminum rod material, at room temperature, the application of wire drawing machine through one or more stretching die die hole, so that its cross-sectional reduction, length increase, strength progress.

  Second, monofilament annealing. Copper, aluminum monofilament in the heating to a certain temperature to recrystallize the method to improve the toughness of monofilament, reduce the strength of monofilament to meet the requirements of wire and cable on the conductive wire core. Annealing process is the key to eradicate the oxidation of copper wire.

  Third, the conductor stranding. In order to improve the flexibility of the power line, in order to lay the device, the conductive core to accept multiple monofilament stranded. From the conductive core of the stranded way, can be divided into rules stranded and non-rules stranded. Non-rules stranded and divided into bundle stranded, flush complex stranded, extraordinary stranded.

  Fourth, the power cord insulation extrusion. Plastic power cord is mainly used to extrude the solid type insulation layer, plastic insulation extrusion of the primary craft requirements of the extruded insulation layer appearance requires lubrication, shall not present the appearance of clumsy, burnt, impurities of poor quality. The cross-section of the extruded insulation layer should be dense and robust, no pinholes visible to the naked eye, to eliminate the presence of air bubbles.

  Fifth, the power cord into line. On the multi-core power cord in order to guarantee the degree of molding, reduce the shape of the power cord, the general need to be stranded for the round. Stranding mechanism is similar to the conductor stranding, because the stranded section diameter is larger, most of the non-return twist method.

  Sixth, the inner sheath. In order to maintain the insulated wire core is not lumped by the armor, the need for proper maintenance of the insulation layer.

  Seven, the power cord outer sheath. Is to maintain the insulation layer of the power cord to avoid the corrosion of the structural parts of the situation. The primary effect of the outer sheath is to improve the mechanical strength of the power cord, chemical erosion, moisture, water immersion, to prevent the power cord burning and other capabilities.

  Power cord is the transmission of current wire, power cord structure mainly has an outer sheath, inner sheath, copper wire. Woven mesh tube is also used for the protection and beautification of the power cord. The production process of power cord must be very stable and mature.
