Suspension type insulator in use, can be as struvite accumulation caused by flashover accident, even lead to islanding, a large umbrella skirt structure, can effectively avoid the other umbrella skirt and equalizing ring is polluted, the eradication of such things to help potential, with an accompanying increase in the insulator in the north and high cold snow area anti ice flashover ability. When the route and direction is greater than 45 degrees, the wire is easy to produce dancing, a threat to the safe operation of power system. The suspension insulator equalizing ring designed to hammer structure can be improved at the same time, the end of the electric field distribution, reduce the natural frequency and the peak transverse vibration insulators effectively, is suitable for the strong wind region and the northwest Valley air outlet used.
