Materials of EN Standard Porcelain Bushing
1. Insulation Body: High-Grade Wet-Process Porcelain
The core insulation is manufactured from premium wet-process electrical porcelain. Fired at extreme temperatures, it achieves exceptional density and a smooth, self-cleaning glaze, delivering outstanding dielectric strength and long-term resistance to environmental degradation.
2. Conductive Core: High-Conductivity Electrolytic Copper
Internally, the conductive components are crafted from high-conductivity electrolytic copper. This material ensures minimal electrical resistance, excellent thermal conductivity, and stable current-carrying performance, effectively controlling temperature rise under heavy loads.
3. Mounting Flange: Anti-Corrosion Metal Alloy
The mounting flange is engineered from high-strength, anti-corrosion metals (such as hot-dip galvanized steel or aluminum alloy). It provides robust mechanical bending strength to withstand conductor tension and severe weather, guaranteeing long-term structural integrity.
4. Sealing System: High-Grade Oil-Resistant Gaskets
To ensure absolute hermetic sealing in oil-immersed transformers, high-grade oil-resistant gaskets are integrated. This reliable sealing technology completely prevents transformer oil leakage and blocks moisture ingress, securing the internal insulation system.
