Heat -resisting hole enlargement generating line stranded conductor structure

The utility model discloses a heat -resisting hole enlargement generating line stranded conductor structure, including the transmission of electricity generating line, be equipped with the embossing aluminum pipe that is used for the hole enlargement strengthen to support the transmission of electricity generating line in the center of transmission of electricity generating line, made by trussing together the texture layer on the outer pipe wall of embossing aluminum pipe, the inseparable rounding of transmission of electricity generating line hank system is outside the embossing aluminum pipe on the pipe wall. The embossing aluminum pipe effectively plays the hole enlargement supported effects who realizes the transmission of electricity generating line, effectively realizes under the condition that does not increase the conducting layer area through the hole enlargement supporting layer external diameter diameter of generating line of transmitting power that has come greatly increased, and then satisfies the requirement of transformer substation's generating line among the large capacity transmission line.
