Cable for high-power energy storage power station with easy heat dissipation and manufacturing method thereof

Abstract

The present application relates to cable heat dissipation technical field, specifically, it relates to easy heat dissipation high-power energy storage power station cable and its manufacturing method. It includes protective layer and the multiple heat dissipation groups set on the surface of protective layer, heat dissipation group includes pre-crack layer, pre-crack layer inside center is provided with pre-crack opening;Pre-crack layer will expand when heated, make pre-crack opening open to both sides, pre-crack opening has fiber mesh hole inside, when pre-crack opening is heated and opened, it will pull the fiber mesh hole and spread its mesh hole, the inner wall of protective layer is provided with multiple inner wall heat dissipation grooves, through the setting of pre-crack layer and pre-crack opening, when the internal temperature rises, the heat expansion of pre-crack layer matrix and the gas expansion in thermal expansion microsphere superposition produce directional expansion stress, drive pre-crack opening deformation, heat dissipation and air convection are carried out heat dissipation;Inner wall heat dissipation groove is isosceles trapezoidal structure in transverse section, so that pre-crack opening can also concentrate heat and quickly open pre-crack opening to dissipate heat inside the cable when the heat is low.
