H2: Wiring Insulator — Material and Construction
Each wiring insulator is produced from high‑grade alumina porcelain, fired at over 1,300 °C using the wet process, achieving maximum density and near‑zero porosity.
The robust porcelain body provides excellent dielectric strength and mechanical durability, ensuring reliable performance in electrical wiring, busbar support, and switchgear applications. The insulator design accommodates various mounting configurations, including through‑hole, base‑mounted, and custom designs.
The hard, glossy glaze — available in brown or gray — provides superior insulating properties and resists surface contamination. This ensures consistent electrical performance throughout the insulator’s service life.
Whether used in indoor switchgear, outdoor installations, or custom electrical assemblies, the Wiring Insulators deliver dependable performance with minimal maintenance.
