Processing technology of copper conductor wire for photovoltaic cable

The invention discloses a processing technology of a copper conductor wire for a photovoltaic cable, and the processing technology comprises the following steps: 1, putting pure copper and pure silver into a smelting furnace for smelting to obtain molten alloy liquid with the silver content of 0.09-0.12%; 2, the alloy liquid melted at the high temperature is cooled through a jacket cooling mold and then crystallized and solidified, so that solidification and crystallization of the whole alloy liquid are completed on the lower portion of the liquid level of the alloy liquid, and the alloy liquid does not make contact with air; 3, upwards drawing the solidified copper rod out of the cooling mold by adopting an upward drawing method to obtain an oxygen-free copper rod; and 4, the oxygen-free copper rod is subjected to wire drawing through a wire drawing machine, and the copper alloy conductor is obtained. According to the oxygen-free copper rod and the manufacturing method thereof, the whole machining process is
