Why Choose Us
Our Technical Advantages
Advanced Material Science
Our proprietary formulation is engineered to achieve exceptional mechanical strength, superior dielectric properties, and long-term stability in harsh environments.
Every batch of raw material is subjected to stringent chemical and physical analysis. We ensure consistent quality by verifying key parameters such as chemical composition, particle size distribution, and sintering behavior before production even begins.
Through controlled firing at high temperatures, we develop a dense, uniform, and fully vitrified microstructure. This eliminates internal porosity, significantly increasing the product’s resistance to tracking, erosion, and electrical puncture.
Strick Routine Test
We use professional inspection fixtures,while others use tape measures. Professional tools enhance efficiency and accuracy
Factory & Quality Certifications
Comprehensive Quality Certifications
We have ISO,KEMA,and Type test reports.
Our core mission is to empower a safer and more resilient electrical grid. We achieve this through an unwavering commitment to quality, rigorous testing, and compliance with international standards of IEC, ANSI,BS,AS, DIN and customers’ drawings.
