The invention discloses a cold-resistant power cable. A conveying mechanism comprises a mounting plate fixed to the surface of a detection mechanism, one side of the mounting plate is fixedly connected with a connecting plate, one side of the connecting plate is fixedly connected with a cable feeding fixing frame, one side of the cable feeding fixing frame is fixedly connected with an inserting rod, the surface of the inserting rod is movably connected with a cable reel, and one side of the mounting plate is in threaded connection with a rotating rod. The invention relates to the technical field of cables. According to the cold-resistant power cable, the cable reel can be quickly inserted into the inserting rod on the surface of the cable feeding fixing frame on the conveying mechanism through the conveying mechanism, the inserting rod is supported in an assisting mode through the limiting frame so that the inserting rod can be quickly fixed, and the cable reel is driven by the recycling mechanism to rotate for take-up, the cable reel rotates under the guidance of the bearing wheel, the operation is convenient, the use is simple, the cable reel can be rapidly wound and unwound, andthe detection efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of cables, in particular to a cold-resistant power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. Our country spans 50 latitudes, and the temperature difference between the north and the south is large. When the power cable is used in the northern region, it will work at low temperature for a general time every year, and the cable sheath made of rubber material will be brittle at low temperature. If the cold resistance of the power cable is insufficient, the embrittled wire The skin will be damaged and leak when it receives a collision, which is not only a waste of energy but also prone to danger. It is necessary to test the cold resistance...
