[0030] Furthermore, the protective jacket 1 is fixedly connected to the radiation-resistant jacket 2, the size of the radiation-resistant jacket 2 is smaller than that of the protective jacket 1, the PVC pipe 3 is fixedly installed inside the radiation-resistant jacket 2, the size of the PVC pipe 3 is smaller than that of the radiation-resistant jacket 2, and the radiation-resistant jacket 2 is made of special radiation-resistant material, has excellent radiation resistance, and can effectively prevent radiation from damaging the PVC pipe 3. At the same time, the radiation-resistant jacket 2 also has good high temperature resistance, corrosion resistance and other properties, and can adapt to various complex working environments.
[0031] The protective jacket 1 further protects the radiation-resistant jacket 2 and the PVC pipe 3 and can prevent external physical damage and chemical corrosion.
[0032] Furthermore, the wires 4 and the reinforcing steel bars 5 are fixedly installed inside the PVC pipe 3, and the reinforcing steel bars 5 are fixedly installed at the center of the PVC pipe 3. There are three wires 4, and the three wires 4 are arranged in a triangle, and each wire 4 has a certain distance from the reinforcing steel bars 5 to ensure the independence and stability of the wires. The fixed installation of the wires 4 and the reinforcing steel bars 5 uses professional fixings to ensure their stability inside the PVC pipe 3 and avoid movement or deformation caused by external forces.
[0033] Specifically, the material of the PVC pipe 3 has excellent insulation and corrosion resistance, and can protect the wire 4 from interference and damage from the external environment.
[0034] Furthermore, the corrosion-resistant layer 6 is fixedly connected to the outer layer of the protective jacket 1 , the high-temperature resistant layer A7 is fixedly connected between the corrosion-resistant layer 6 and the semi-silver fiber layer 8 , and the semi-silver fiber layer 8 is fixedly connected between the high-temperature resistant layer A7 and the rubber layer 9 .
[0035] Specifically, the rubber layer 9 is fixedly connected between the semi-silver fiber layer 8 and the high temperature resistant layer B10. The structural design of these layers enables the entire protective jacket to have excellent corrosion resistance and high temperature resistance.

A PVC pipe 3 is arranged inside the radiation-resistant jacket 2. The PVC pipe 3 is the main part of the wire and is used to accommodate the wire 4 and the reinforcing steel bar 5. The wire 4 is responsible for transmitting current, while the reinforcing steel bar 5 plays a role in enhancing the structural stability of the wire. The design of the PVC pipe 3 allows the wire 4 and the reinforcing steel bar 5 to be arranged in an orderly manner inside the wire, ensuring the overall performance of the wire.
[0040] The outer layer of the protective jacket 1 is provided with a corrosion-resistant layer 6, which can effectively resist the erosion of external corrosive substances and protect the service life of the wire. One side of the corrosion-resistant layer 6 is connected to a high-temperature resistant layer A7, which is made of high-temperature resistant materials and can maintain the performance of the wire stable in a high-temperature environment.
[0041] The semi-silver fiber layer 8 is located at the bottom of the high temperature resistant layer A7.
