Cold-Resistant Medium-Voltage Power Cable

A cold-resistant medium-voltage power cable, comprising:

• a cable body (1);
• wherein a bending protection sleeve (2) is slidably sleeved over an outer end of the cable body (1);
• a clamping disc (3) is bolted to each of a left end and a right end of the bending protection sleeve (2), and the clamping disc (3) is slidably engaged with the cable body (1);
• a regulation protection cavity (21) is provided inside the bending protection sleeve (2);
• a flexible electric heating patch (4) is fixedly connected to an inner wall of the regulation protection cavity (21) on a side thereof that is far from the cable body (1);
• and a bending sensing assembly (5) configured to cooperate with the flexible electric heating patch (4) is arranged between a left inner wall and a right inner wall of the regulation protection cavity (21);
• and
• the bending sensing assembly (5) comprises a trigger pad (51) fixedly connected to each of the left inner wall and the right inner wall of the regulation protection cavity (21);
• an inner telescopic sensing coil (52) is fixedly connected to a right end of the trigger pad (51) that is fixed to the left inner wall of the regulation protection cavity (21);
• an outer telescopic sensing coil (53) is fixedly connected to a left end of the trigger pad (51) that is fixed to the right inner wall of the regulation protection cavity (21), and the outer telescopic sensing coil (53) is located on an outer side of the inner telescopic sensing coil (52);
• an inner sensing contact block (521) is fixedly connected to a right end of the inner telescopic sensing coil (52);
• an outer sensing contact block (531) configured to cooperate with the inner sensing contact block (521) is fixedly connected to a left end of the outer telescopic sensing coil (53);
• and the flexible electric heating patch (4) is connected to the inner sensing contact block (521) and the outer sensing contact block (531) via wires.
