Composites can be extremely good insulators, so you will find them in a variety of electrical applications including electrical pads and undergournd enclosures. They are typically only 1/3 the weight of concrete enclosures and provide a high compressive, flex and tensile strengths. Because they are lighter weight and easier to handle, they have reduced installation costs over concrete systems. Composite enclosures are corrosion resistant and stable under freeze/thaw conditions.
