The manufacture of electrical insulation components for switchgear represents the core of The Gund Company. Switchgear is made up of a combination of electrical switches and fuses or circuit breakers that are used to isolate, control, and protect electricity distribution to the end equipment. The gear is typically classified by operating voltage and fall into the following three categories: low voltage < 1kV AC, medium voltage 1 – 75 kV AC, and high voltage 75 – 230 kV AC.

Low voltage switchgear is located in buildings and consists of circuit breakers, disconnects, power distribution centers and meter housings. Medium voltage switchgear includes pad mount cabinets, circuit breakers, and large motor control centers. Most high voltage switchgear is operated at outdoor substations and utilizes air as the primary insulator.

As an integrated manufacturer of NEMA Grade GPO-3 Glass Polyester Laminate, The Gund Company supplies phase barriers, pultruded GPO-3 angle and channel, bus duct windows, and bus supports. We also manufacture our proprietary PolyPro FR Flame Retardant Polypropylene, water resistant insulation for motor control centers, watt-hour meters, and power supplies.

Power Electronics Applications

Modern power electronics equipment involves the use of solid state electrical devices to control and convert electrical power. Most of these systems employ devices such as diodes, thyristors, and power IGBTs. The conversion equipment is classified by the type of input and output power. The four categories include rectifiers (AC to DC), inverters, (DC to AC), and converters (AC to AC or DC to DC). As power requirements have increased and design envelopes have decreased, the need for cost-effective, high-performance electrical insulation has intensified.

As a vertically integrated manufacturer of insulation materials, The Gund Company supplies NEMA Grade GPO-3 Glass Polyester Laminate (UPGM 203) glass polyester laminate for power inverters, converters, and storage devices. We also manufacture our proprietary PolyPro FR Flame Retardant Polypropylene, water resistant insulation for board liners, bus bar covers, and power supplies

Thermoset Rigid Composites

Thermoset rigid composites are composite materials in the “plastics” family. Generally speaking, plastic materials can be either thermoset or thermoplastic. By definition, thermoset materials maintain their dimensional stability at elevated temperatures while most thermoplastic material melt (or lose dimensional stability) at high temperatures.

Because thermoset composite materials maintain their dimensional stability at high temperatures, these materials work well in electrical insulating applications. Electrical equipment tends to generate a tremendous amount of heat due to the concentration of electrical wiring in a small space. The passage of electricity through electrical wires creates thermal energy or heat due to the resistance offered by copper or aluminum to the passage of electrons through their valence structures. Thus, the materials that insulate the copper or aluminum conductors must be able to withstand the thermal energy created without deforming or melting. For this reason, thermoset composite materials find common application in electrical equipment and other applications where dimensional stability at elevated temperatures is required.

By definition, composite materials are assembled by combining two or more materials. In the case of thermoset composites, a base material such as glass and cotton cloth serves as reinforcement. The reinforcement is held together with a thermosetting resin such as epoxy, phenolic, or melamine. Thermoset composite engineering, manufacturing, and fabricating is a core focus of The Gund Company.

Flexible Materials

Flexible materials can be homogeneous and heterogeneous in their makeup and can be made from a multitude of base materials. Flexible materials do not exhibit rigidity under normal conditions. In general, they cannot be machined, but are converted with standard processes. Materials that are considered to be flexible range from papers to elastomeric materials. The Gund Company manufacturers and converts a variety of flexible materials used in electrical and mechanical applications.

The Gund Company offers numerous flexible materials, custom designed to fit customer applications. To learn more about the materials we offer and their applications, click Learn More below.

An elastomeric material is any material exhibiting elastic or rubber-like properties. Generally speaking, elastomeric materials are measured in material type, compound, and durometer (the hardness of the material). Since there are such a wide variety of elastomeric materials, the application is critical to understanding the best material compound for the job. The Gund Company offers a wide range of elastomeric materials that can be converted into an infinite number of shapes and sizes to meet your specific application.
