Abstract
A weathershed for use in a composite insulator includes a molded polymer body. The body configuration is such that the leakage distance across the weathershed is increased, while at the same time the amount of material needed is reduced. This provides a lightweight and easily manufactured weathershed. The weathershed includes a radially curved outer edge which reduces the electric field gradient and also reduces the tendency to trap contaminants.
