FAQs of Epoxy Dog Bone:
Q: How is the Epoxy Dog Bone used in electrical equipment?
A: The Epoxy Dog Bone serves as an insulating spacer or slot separator in motors, generators, transformers, and switchgear, preventing electrical short circuits and ensuring reliable operation under high voltage.
Q: What benefits does epoxy resin with fiberglass reinforcement provide?
A: The combination of epoxy resin and fiberglass reinforcement delivers superior electrical insulation, mechanical strength, and resistance to heat, ensuring long-term durability and safety in electrical and thermal environments.
Q: When should I consider a custom size or color for the Epoxy Dog Bone?
A: Custom sizes and colors are recommended for specialized applications where standard dimensions or colors may not fit the slot design or aesthetic requirements of your equipment. Customization ensures the optimal fit and performance.
Q: Where are these Epoxy Dog Bones commonly installed?
A: These components are typically found in high-voltage electrical equipment such as motors, generators, transformers, and switchgear, where reliable insulation and slot separation are critical.
Q: What is the standard manufacturing process for these profiles?
A: Epoxy Dog Bones are manufactured using a pultrusion technique, where epoxy resin is reinforced with either woven or unidirectional fiberglass to achieve precise shapes and consistent mechanical properties.
Q: How does surface treatment affect the performance of the Epoxy Dog Bone?
A: A smooth finish on the surface minimizes electrical tracking and contamination, further enhancing the dielectric performance and longevity of the insulation in electrical assemblies.
