High Performance Porcelain Post Insulators for Electrical Power Systems
Porcelain post insulators are essential components in electrical power systems, providing both mechanical support and electrical insulation. At Changsha Rich Power, we manufacture high-quality porcelain post insulators suitable for various applications including electrical substations, switchyards, transmission lines, and industrial power systems.
Key Features of Our Post Insulators
Our porcelain post insulators are manufactured using high-grade electrical porcelain with optimal alumina content for superior mechanical and electrical properties. The porcelain is fired at high temperatures to ensure excellent density and uniformity. The glaze provides smooth surface finish for improved pollution performance and easy cleaning.
Design Standards and Certifications
Our post insulators are designed and tested according to international standards including IEC 60273, ANSI C29.10, DIN 48110, and other relevant specifications. We can also manufacture insulators to meet specific customer requirements and local standards. All insulators undergo rigorous testing including mechanical load tests, power frequency withstand tests, impulse withstand tests, and temperature cycle tests.
Customization Options
We offer various customization options including different mounting arrangements, special creepage distances for polluted areas, special fittings, and custom colors. Our engineering team can work with you to develop post insulators for specific applications and challenging environments.
