The molecular structure of silicones makes them ideal for use as insulation in the transmission and distribution sector. For example, when covered with pollution layers, silicone composite insulators have much lower leakage currents than insulators of porcelain, glass or EPDM. This prevents pollution flashovers, even if the surface is extremely dirty.

And insulators are not the only products to benefit from silicones. Silicone insulating materials are used in modern transmission and distribution applications wherever operational safety standards are high and long service lives are required, such as silicone fluid in transformers or silicone elastomer terminations of high-voltage cables.
