In high-voltage electrical systems, insulation reliability is non-negotiable. Aputon‘s Pultruded Glass Insulation Spacer is engineered to meet the most demanding dielectric and mechanical requirements. Manufactured from high-strength glass fiber reinforced polymer (GFRP) through an advanced pultrusion process, these spacers provide exceptional electrical insulation properties, with dielectric strength exceeding 100kV and arc resistance above 180 seconds. The material composition—glass fibers combined with thermosetting resin—delivers outstanding tensile and compressive strength while maintaining a lightweight profile for easy installation. Our spacers are available in multiple insulation classes, including Class F (155°C), Class H (180°C), and Class C (200°C), making them suitable for dry-type transformers, reactors, switchgear, and substation applications. At Aputon Electrical, we are driven by a passion to exceed expectations and enhance the operational capabilities of businesses worldwide. We believe in building long-lasting relationships with our clients by providing reliable, high-quality solutions that not only meet but anticipate their electrical needs, ensuring progress and sustainability for communities around the globe. Choose Aputon for insulation components that combine proven performance with custom-engineered precision.
