Furthermore, four fixing pieces are uniformly distributed in the armor layer, and the inner sheath, the armor layer and the outer sheath are connected into a whole.

Furthermore, the fixing piece is an elastic fixing piece in a cross shape, and the upper end and the lower end of the fixing piece respectively penetrate through the armor layer and are fixed in the inner sheath and the outer sheath.

The utility model has the beneficial effects that:

1. the waterproof performance is good, a waterproof layer is arranged between the cable core and the outer sheath to protect the cable core from water, and the waterproof layer adopts a rainwater expansion waterproof tape to fasten and seal the cable core, so that the phenomena of water leakage and water seepage are avoided;

2. the flame retardant effect is good;

3. the cable has the advantages that the radiating effect is good, the plurality of hollow vent pipes extending along the radial direction are arranged in the inner sheath, and when the cable is used for heating for a long time, cold air can be exhausted through the hollow vent pipes by an external air source, so that the temperature in the cable is reduced, and the service life of the cable is prolonged;

4. the anti-torsion and anti-impact performance is good, the inner sheath, the armor layer and the outer sheath can be connected into a whole through the fixing piece to play a role in supporting and connecting, so that the anti-torsion performance of a cable core is improved when the cable is dragged or twisted, and meanwhile, when instantaneous impact is encountered, the elastic fixing piece and the integral structure of the inner sheath, the armor layer and the outer sheath can also play a good role in protecting the cable and prevent the cable from being broken under the instantaneous impact.
