Example 1

[0015] like Figure 1 As shown, this embodiment discloses the first implementation of the present invention, and the technical solution adopted is to include unit lines, such as... Figure 1 As shown, it uses ultra-high molecular weight polyethylene split-film fiber 4 as the core. After the split-film fiber 4 is passed through a copper tube serving as conductor 3, the copper tube is stretched and its diameter reduced using a caliper to ensure a tight bond between conductor 3 and split-film fiber 4. A tensile layer 2 is wrapped around the conductor 3. The tensile layer 2 is a glass fiber-aramid yarn woven layer, which is woven from composite fibers twisted together from glass fiber and aramid yarn. During the weaving process, a satin weave is used to ensure the theoretical strength of the fibers. A first insulation layer 1, made of polyvinyl chloride, is wrapped around the tensile layer 2. The unit wire can be used as a standalone wire.

[0016] The ultra-high molecular weight polyethylene split film fiber 4 used in this embodiment is Sundless split film fiber from Zhengzhou Zhongyuan Defense Materials Co., Ltd. It is obtained by processing ultra-high molecular weight polyethylene powder into a film, cutting the film into strips, and then bundling and twisting the strips. Example 2

[0017] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the unit wire has three strands arranged in a ring array.

The quartz wool 502 covers the water-blocking yarn 501, which can improve the flame retardant performance of the cable. A flame retardant layer 6 is wrapped around the quartz wool 502. The flame retardant layer 6 is ceramic fiber cloth, which further improves the flame retardant performance. Outside the flame retardant layer 6 is a waterproof layer 7 composed of water-blocking tape. Outside the waterproof layer 7 is a second insulation layer 8, which is a polyethylene insulation layer. The polyethylene insulation layer can not only provide insulation but also provide radial water blocking. The water-blocking tape of the waterproof layer 7 can block the seepage of trace amounts of water.
