The installation of the elastic bands 12 can evenly distribute the multiple support bars 7 on the outer wall of the fireproof layer 5, and at the same time facilitate the fixation of the multiple support bars 7, which is convenient for later operation.

[0022] Reference Figure 1 A lightweight connecting frame 3 is clamped between multiple semi-conductive conductor shielding sleeves 1, and the interior of the electromagnetic shielding sleeve 4 is filled with insulating filling glue 13. The lightweight connecting frame 3 plays a positioning role to prevent multiple semi-conductive conductor shielding sleeves 1 from being entangled together during the production process, affecting the later production.

[0023] Reference Figure 1 and Figure 2 A plurality of jacks 10 are provided inside the buffer layer 8, and the plurality of jacks 10 are evenly distributed in a ring shape. A soft rubber tube 11 is fixedly connected inside the jack 10.

[0024] Reference Figure 1-Figure 3 The support strip 7 is made of carbon fiber reinforced plastic, the fireproof layer 5 is made of alumina fiber, and the electromagnetic shielding sleeve 4 is made of conductive polymer. Carbon fiber reinforced plastic has excellent mechanical strength and lightweight characteristics. It can significantly reduce the weight of the cable while ensuring the mechanical protection performance of the cable, making it easy to lay and install. Alumina fiber has a good fireproof and heat-insulating effect, and the cable can continue to work under high temperature conditions. The electromagnetic shielding sleeve 4 is made of conductive polymer, which further improves the electromagnetic shielding performance of the cable and reduces electromagnetic interference.

[0025] Working principle: In the process of producing new armored cables, multiple semi-conductive conductor shielding sleeves 1 are installed on the periphery of the lightweight connecting frame 3. The lightweight connecting frame 3 plays a positioning role to prevent the multiple semi-conductive conductor shielding sleeves 1 from being entangled together during the production process, affecting the later production. The interior of the semi-conductive conductor shielding sleeve 1 is provided with multiple conductor cores 2, and the conductor core 2 is used to transmit electrical energy or signals. After the multiple semi-conductive conductor shielding sleeves 1 are fixed, an electromagnetic shielding sleeve 4 made of a conductive polymer is set on the periphery of the multiple semi-conductive conductor shielding sleeves 1 to improve the electromagnetic shielding performance of the cable and reduce electromagnetic interference. After that, the insulating filling glue 13 is injected into the electromagnetic shielding sleeve 4 to position and fix the semi-conductive conductor shielding sleeve 1 in the electromagnetic shielding sleeve 4, and the insulating filling glue 13 solidifies. Finally, a fireproof layer 5 made of alumina fiber is sheathed on the outer periphery of the electromagnetic shielding sleeve 4. Alumina fiber has excellent fireproof and heat-insulating effects, and the cable can continue to work under high temperature conditions. After the fireproof layer 5 is laid, multiple support strips 7 made of carbon fiber reinforced plastic are pulled apart by elastic bands 12, and multiple support strips 7 are sheathed on the outer periphery of the fireproof layer 5. Then, a buffer layer 8 with a socket 10 is sheathed on the outer periphery of the support strip 7, and a soft rubber tube 11 is inserted into the socket 10. The soft rubber tube 11 has excellent elasticity and can play a good buffering and anti-collision role. After the sheathing is completed, fixing glue is injected between the fireproof layer 5 and the buffer layer 8 to fix the support strip 7. Finally, an outer sheath 9 is fixedly sheathed on the outer periphery of the buffer layer 8. After installation is completed, a new armored cable is obtained.
