Welcome to Guangzhou Aputon Electrical Co., Ltd., where pioneering technology meets world-class quality. Since our inception in December 2015, we have positioned ourselves at the forefront of the electrical industry with our headquarters in the dynamic industrial regions of Guangzhou and Foshan. We specialize in customized design, manufacture, and global distribution of high and low voltage electrical sets, transformers, cable accessories, and cutting-edge UPS energy storage solutions. As an ISO9001, ISO14001, and OHSAS18001 certified enterprise, we are recognized for our commitment to innovation and excellence. Our products are engineered to lead the market in performance and sustainability, catering to the complex and evolving needs of our diverse clientele across more than 20 countries, including key markets in Asia, Africa, Europe, and the Americas.

Transformers and reactors generate significant heat during operation, demanding insulation components that perform reliably at elevated temperatures. Aputon’s Pultruded Glass Insulation Spacers are manufactured with high-temperature resin systems that meet UL 1446 insulation system compatibility requirements for Class F (155°C), Class H (180°C), and Class R (200°C) applications. Even at these extreme temperatures, our spacers maintain flexural strength exceeding 80,000 psi and compressive strength above 45,000 psi, ensuring structural integrity under continuous thermal cycling and mechanical load. The pultrusion process creates a homogeneous structure with consistent glass fiber distribution, eliminating weak points common in molded or laminated materials. For dry-type transformer coil winding applications, our spacers provide reliable electrical separation and mechanical support throughout the equipment‘s service life. 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.
