[0025] In the cable production process, the cable conductor (metal part) needs to be preheated to remove the moisture on the surface of the conductor, prevent bubbles from appearing in the process of subsequent covering of the insulating outer skin, and improve the adhesion of the insulating material to the conductor. The common cable conductor preheating method is to directly heat the conductor by using a heating pipe. However, due to the existing heating pipe structure which is usually external and exposed to the air, the heat generated during the heating process is easily lost and not easily concentrated on the conductor metal, resulting in unsatisfactory heating effect. Especially in the cable production process, the cable conductor needs to be continuously moved after preheating, which makes the heat loss more serious and further reduces the preheating effect.

[0026] In addition, the heat of the conductor metal after heating is not effectively preserved. Without heat preservation treatment, the heat is easily lost quickly, which causes the conductor metal to cool down again before being covered with the insulating outer skin, affecting the adhesion effect of the subsequent insulating layer and the overall quality of the cable product.
