Technical Field

[0001] The utility model relates to the technical field of cable manufacturing, in particular to a double-sheathed anti-insulation welding cable. Background Technique

[0002] In multiple industries such as electric power, construction, machinery manufacturing, and ships, welding cables, as key components for power transmission, undertake the important task of transmitting electrical energy from the power source to the welding equipment. Their performance directly affects the efficiency, quality, and safety of welding operations. With the continuous development of industrial technology, the requirements for welding cables are also increasing day by day, especially in aspects such as electrical conductivity, heat resistance, mechanical strength, abrasion resistance, and service life.

[0003] Traditional welding cables usually adopt single-layer or multi-layer insulation structures, and the conductors are mostly composed of multiple strands of fine copper wires stranded together to meet the needs of different current transmissions. However, in actual use, traditional welding cables often face problems such as easy aging of the insulation layer, insufficient mechanical strength, and poor abrasion resistance, resulting in shortened service life of the cable and even possible safety accidents. Content of the Utility Model

[0005] To achieve the above object, the utility model provides a double-sheathed anti-insulation welding cable, including a cable body. The cable body includes a main conductor arranged inside the cable body. Around the main conductor, several groups of signal transmission cables are arranged in cooperation. Between each group of adjacent signal transmission cables, signal strengthening cables are arranged in cooperation. The signal transmission cables and the signal strengthening cables are provided with an inner cable sheath in cooperation, and an outer cable sheath is arranged outside the cable body.

[0006] As a further improvement of the utility model, to ensure the stable structure of the main conductor inside the cable, the main conductor includes three groups of main copper cores arranged at the central position of the cable body. Inside each group of the main copper cores, a structure of one center line and six peripheral lines is arranged. The center line and the peripheral lines are stranded by multiple strands of ultra-fine bare copper wires.

[0007] As a further improvement of the utility model, to ensure a certain insulation inside the cable, the inner cable sheath is arranged to cover the outside of the cable body structure. The inner cable sheath is made of PVC insulating material, and the thickness of the inner cable sheath is between 1.3 - 1.6 mm.

[0008] As a further improvement of the present utility model, in order to ensure the stability of the external structure of the cable, the cable outer sheath is arranged to cover the outside of the cable inner sheath. The cable outer sheath is made of PVC insulating material, and the thickness of the cable outer sheath is between 0.8 - 1.00 mm.

[0009] As a further improvement of the present utility model, in order to ensure that the cable has a certain heat resistance, a heat-resistant shielding layer is arranged between the cable inner sheath and the cable outer sheath.

[0010] As a further improvement of the present utility model, in order to facilitate providing sufficient electrical insulation and mechanical protection, a single layer of overlapping 0.04 * 20 mm PTFE film is wound around the outer layer of the center line and the peripheral lines.

[0011] When the present utility model works, first, multiple strands of ultra-fine bare copper wires are stranded according to a specific structure to form the main conductor of the cable. An inner sheath is arranged on the outside of the main conductor. The inner sheath is usually made of insulating material to provide preliminary electrical insulation protection for the conductor. Around the main conductor, several groups of signal transmission cables are arranged in cooperation. These signal transmission cables are used to transmit various signals related to welding operations. Between each adjacent group of signal transmission cables, a signal strengthening cable is arranged in cooperation. The function of the signal strengthening cable is to improve the stability and anti-interference ability of signal transmission. The entire internal structure of the cable including the main conductor, signal transmission cables, and signal strengthening cables is covered with a cable inner sheath made of PVC insulating material. Outside the cable inner sheath, a cable outer sheath made of PVC insulating material is further covered. The thickness of the cable outer sheath is between 0.8 - 1.00 mm, which further enhances the mechanical strength and wear resistance of the cable and provides additional environmental protection.

[0012] The beneficial effects of the present utility model are as follows: The present utility model provides a double-sheath anti-insulation welding cable. The cable adopts a double-sheath structure, and both layers of sheaths are made of insulating materials, providing double electrical insulation protection. Optionally, a heat-resistant shielding layer is arranged between the cable inner sheath and the cable outer sheath. This shielding layer can effectively block the influence of external high temperature on the internal structure of the cable. The main conductor adopts a structure of a center line and peripheral lines stranded by multiple strands of ultra-fine bare copper wires. This design makes the conductor have higher flexibility and conductivity. Several groups of signal transmission cables are arranged around the main conductor, and signal strengthening cables are also arranged in cooperation between each adjacent group of signal transmission cables. This design improves the stability and anti-interference ability of signal transmission and ensures precise control during the welding process. BRIEF DESCRIPTION OF THE DRAWINGS
