Abstract
The application discloses a multi-core combined lightning protection cable and relates to the technical field of power cables, which comprises a first framework, a plurality of fins are fixedly arranged on the inner side of the first framework, a second framework is arranged between the fins on the inner side of the first framework, the inner space of the first framework is divided into a first circulating cavity and a second circulating cavity through the second framework, the first circulating cavity and the second circulating cavity are filled with cooling liquid, a plurality of first electric cores are embeddedly arranged on the outer side of the first framework through twisting, a second electric core is arranged between adjacent first electric cores through twisting, an aluminum foil shielding layer is arranged on the outer side of the first electric core and the second electric core, a heat insulation layer is arranged on the outer side of the aluminum foil shielding layer, and a silk screen braiding layer is arranged on the outer side of the heat insulation layer. The first electric core and the second electric core are used for power conduction, the aluminum foil shielding layer plays a role in preliminary shielding, the aluminum foil shielding layer has a very good shielding effect on interference, and the heat generated by the first electric core and the second electric core is easily locked in the aluminum foil shielding layer.
