Dielectric Strength

Dielectric Strength is a critical property for any material with a primary function as an electrical insulator. In simple terms, dielectric strength is the ability of an insulating material to
withstand applied electrical stress. It is defined as “the maximum electric field strength that a material can withstand intrinsically without breaking down; i.e., without experiencing failure of its insulating properties.”

Compressive Strength in Composite Materials

Compressive strength, also known as compression strength, is an important mechanical property for design engineers when a material is placed under direct compression loads. Compressive strength in metals is not typically found as critical stress. However, in other materials such as concrete, plastic, wood, and composite, compressive strength can easily be the critical design property if the loading is primarily in compression. The compressive strength behavior of common materials such as metals, concrete, and wood is well documented. Composite materials exhibit some unique compressive strength behavior, depending on the composite construction. This technical paper will provide an overview of compressive strength related to composite materials.

High-Temperature Glass Epoxy

Materials technology continues to evolve, offering higher performance materials for more demanding customer applications. Often, manufacturers fail to review their specifications to take advantage of these newer materials that provide improved performance at a lower cost.

Unfortunately, there is a tremendous amount of confusion in the marketplace regarding the thermal performance of insulation materials. A related document from The Gund Company, “Thermal Performance of Insulation Materials – A Review of Terminology & Methods,” addresses this topic specifically.

Water Absorption

The Gund Company fabricates custom electrical insulating components for power systems equipment, including generators, transformers, switchgear, power supplies, electric motors, and related equipment. Insulation material selection can be quite challenging due to the number of factors that influence insulation system engineering and insulation component design.
