A windage yaw preventing rigid insulating inhaul cable of a high-voltage power transmission line comprises a bar body. The two ends of the bar body are connected with hardware fittings respectively. The bar body comprises a bar core arranged inside and an umbrella skirt located outside the bar core, wherein the umbrella skirt is made of silicone rubber composite materials, and the bar core is a pull bar made of epoxy resin glass fibers. The windage yaw preventing rigid insulating inhaul cable of the high-voltage power transmission line can effectively prevent a wire from deflecting from a pole and tower under the action of heavy wind, avoid trip caused by windage yaw of the line and improve the safe operation level of the power transmission line.
