1.Technical utilize:hot press pouring technics,which can control the required tolerance to a range.The size is very precise.
2.The required connecting hardware fittings used in interior line of electric equipment is copper. It can be galvanized,all choose high quality environmental protection hardware fittings material,accord with ROHS standard.
3.We can produce and assemble based on the customers'requirement.Speedy delivery,reasonable price.4.The product process of high voltage porcelain insulator involves the following major manufacturing operations:
Grinding → Clay making → Pugging → Moulding → Drying → Glazing → Kilning → Testing → Final product
