The sliding connection between the extension plate 17, the arc plate 27 and the limit plate 9 ensures the adaptability of the cable during use. After the cable is installed, the teeth 13 on the extension plate 17 and the teeth 28 on the arc plate 27 engage with each other to form a stable mechanical connection to prevent the cable from loosening or falling off during operation. At the same time, the rotation of the connecting column 6 enables the arc plate 27 to adjust its angle, further enhancing the fixing effect of the cable. The setting of the limit plate 9 ensures that the sliding range of the extension plate 17 is limited, thereby ensuring that the cable will not exceed the preset safety range during movement, avoiding damage caused by excessive stretching or compression. During the operation of the cable;

The waterproof coating 12 is made of polyethylene and has excellent waterproof properties. It can effectively prevent moisture from penetrating into the cable, avoiding electrical failures caused by moisture, ensuring the safety and durability of the cable in harsh environments and reducing the risk of electrical failure. The insulating coating 15 is made of cross-linked polyethylene and has excellent insulation properties. It can isolate the cable 1 from contact with the external environment and prevent leakage and short circuit accidents. The corrosion-resistant coating 16 is made of polyvinyl chloride and has strong corrosion resistance. It can resist the erosion of chemical substances and protect the internal structure of the cable from damage. Through this design, the flame-retardant mining power cable can maintain efficient and stable working conditions in complex mine environments, ensuring the safety and reliability of the power supply.
