The utility model discloses a three-core
submarine cable capable of bearing high
metal shielding
short circuit current, comprising a wire core unit (1) and a sheath unit (2), the sheath unit (2) is used for wrapping and shaping the wire core unit (1), the wire core unit (1) comprises three
electric signal core wires (1.1), the three
electric signal core wires (1.1) are uniformly arranged in an array along the circumferential direction, the inner layer of each
electric signal core wire (1.1) comprises a
copper wire (1.1. 1), and the outer layer of each electric
signal core wire (1.1) comprises a
copper wire (1.1. 1). The outer layer of the electric
signal core wire (1.1) comprises a
metal shielding layer (1.1. 2), the
metal shielding layer (1.1. 2) comprises a
copper wire layer (1.1. 2.1) and a lead sheath layer (1.1. 2.2), and the lead sheath layer (1.1. 2.2) is arranged on the outer side of the
copper wire layer (1.1. 2.1). The three-core
submarine cable capable of bearing the high metal shielding short-circuit current combines the
high conductivity of the copper wires and the metal shielding layer formed by the high strength of the lead sheath.
