A wind deflection resistant insulated support device comprises an insulated pillar, an insulated connecting rod and a flange. An insulated buffer layer covers the outside of the insulated connecting rod which is positioned on the top. The flange positioned on the bottom is prepared from a metal material, and the other parts are all insulated materials. Thus, it can be ensured that the wind deflection resistant insulated support device has enough strength to withstand multiple impacts of a cable clamp or wire during wind deflection of an insulator. By the adoption of the wind deflection resistant insulated support device, stoppage caused by tripping and reclosing failure after wind deflection of a real circuit can be solved, safe and stable operation capability of the circuit is greatly raised, and normal operation of a power grid is guaranteed.
