Embodiment Construction
[0020] The invention is applied to high-voltage transmission lines of all voltage levels prone to wind deflection, especially to 500kV high-voltage transmission lines.
[0021] like figure 1 As shown, the cable 1 of the present invention includes a rod body 12, the upper and lower ends of the rod body 12 are respectively connected with high-voltage end fittings 11, the rod body 12 includes an shed 13 and a rod core 14, and the surface layer of the rod body 12 is an insulating shed 13. , the umbrella skirt 13 is a silicone rubber composite material. The rod core 14 is located in the umbrella skirt 13, and the rod core 14 is an epoxy resin glass lead rod. The high-voltage end fittings 11 are used to connect with the tower body. When connecting and installing, you only need to punch holes in the tower body and install the commonly used matching connection fittings, which is easy to operate.
[0022] like figure 2 As shown in the figure, the single-circuit line of the 500kV do...
