For a heavy loading condition, what is the corresponding ice thickness?

Ice loading increases the weight and drag on aerial cables, so designs assume a specific ice thickness to represent worst-case winter conditions. For the heavy loading scenario, the standard assumption is half an inch of ice. This level is enough to markedly raise tension and sag, making it the typical value used for heavy-ice design checks. A quarter inch represents light icing, while three-quarters and one inch would reflect more extreme conditions that go beyond the common heavy-loading case. So, the corresponding ice thickness for heavy loading is one-half inch.
