Electric Power Industry Thermoset Composites

Thermoset Composite Parts for the Electric Power Industry

The electric power industry keeps everything running—from homes and hospitals to factories and data centers. As power generation and distribution systems evolve, reliable, high-performance materials are critical to ensuring uptime, safety, and long-term durability.

Thermoset composites are non-conductive, heat-resistant, and dimensionally stable—making them ideal for insulators, bushings, arc barriers, and structural components used in power generation and distribution equipment. Atlas Fibre supplies precision-machined parts and fabrication-ready materials designed for high-voltage applications and demanding environments. Our thermoset composites help reduce weight, resist corrosion, and extend the lifespan of critical power infrastructure.

We work directly with power system manufacturers and utility providers to reduce cost, minimize complexity, and deliver consistent quality—on time and at scale.

Benefits of Composite Materials for the Power Generation Industry

The components used in the power generation industry must be able to withstand high-impact, high-temperature environments. These parts must also provide electrical insulation and not conduct electricity.

Thermoset composite materials meet all of these requirements. The materials are produced during a high-pressure lamination process, which sets their physical and chemical properties. When used in the electric power industry, thermoset materials provide the following benefits:

High strength-to-weight ratio: Thermoset composites are known for being lightweight, weighing less than metal or wood parts. They also have a comparatively high strength-to-weight ratio. For example, G10, a glass epoxy composite, has a tensile strength-to-weight ratio that is nearly double that of aluminum.
Insulation: Composites retain insulating properties at high temperatures, making them ideal for use in power generation. Materials like G10 don’t conduct electricity well, so they provide superior insulating properties.

Corrosion resistance: Exposure to oxygen causes corrosion, the gradual destruction of materials. Corrosion is common with metals, making them weaken over time. Thermoset composites resist corrosion, which extends their lives and allows them to stay strong.
UV resistance: Many of the parts used in electric power generation experienced prolonged sun or ultraviolet light (UV) exposure. Thermoset composites can be made UV-resistant and won’t become weak or damaged after hours in the sun.
Dimensional stability: Thermoset composites offer superior dimensional stability, meaning they retain their form, fit, and function throughout their lives.
Flexibility: There is no one-size-fits-all option for thermoset composites. We work with each customer to create materials and parts based on their unique needs. We machine phenolic and glass thermosets for the electric power industry.
