SINTYRON Customized M5 M6 M10 M12 Thread High Voltage Ceramic Insulators


Product description:
High Voltage Alumina Ceramic Insulators are high-performance electrical insulation components crafted from high-purity alumina
(Al₂O₃) ceramic as the core raw material, via processes of powder molding, high-temperature sintering, precision machining and
surface finishing. With alumina content typically ranging from 95% to 99.7%, the product is a key foundational part for high-voltage,
ultra-high-voltage power transmission and distribution systems, electrical equipment and power stations, dedicated to isolating live
conductors and supporting electrical components under high-voltage working conditions.
