Referring to fig. 1 and 2, normally, the heat-resistant conductor 37 passes through the capacitance current, and when the whole circuit connected with the cable body 2 is short-circuited, the copper strip 35 can pass through as the short-circuited current to protect the cable. Since an air gap is easily formed between the insulating layer 12 of the outermost layer of the heat-resistant conductor 37 and the copper tape 35, a partial discharge is easily generated between the insulating layer 12 and the copper tape 35.

Referring to fig. 1 and 2, the outer protective layer 22 is wrapped outside the plurality of single cables 3, and since the cable body 2 is applied to a high-temperature scene, the fireproof layer 21 is coated on the outer surface of the outer protective layer 22, so that the cable body 2 is protected. A filling space is formed between the outer protection layer 22 and the single cable 3, and the filling space is filled with filler, because the cable body 2 is applied to a high-temperature scene, a gap is easily formed between the filler and the outer protection layer 22 and between the filler and the single cable 3, the gap is easily subjected to water vapor formation due to repeated changes of high bottom temperature, and the filler in the filling space is a water absorbing material.
