Extrude a neoprene rubber same as the inner sheath layer (5) on the outer side of the Kevlar braided layer (6) to form an outer sheath (7), so that the inner sheath layer (5), the Kevlar braided layer (6), and the outer sheath (7) form an integral whole; The thicknesses of the power liquid silicone rubber coating (14), the control liquid silicone rubber coating (24), and the network liquid silicone rubber coating (34) are 0.008 - 0.012 mm.
