Manufacturing Excellence
Our advanced firing process suspends insulators from the bottom during porcelain firing, ensuring straight cores without curvature. This method increases production costs but delivers superior mechanical strength, beautiful finish, and significantly higher product qualification rates.
Premium Materials & Construction
- Metal Components: High-density ductile or malleable iron caps, hot-dip galvanized with zinc thickness meeting IEC and ASTM standards
- Insulation Core: High-aluminum porcelain C130 with hard, shining glaze in grey or brown colors
- Assembly: Portland cement assembly providing exceptional mechanical performance and reliability
Applications
Designed for transmission and distribution lines up to 69KV. These insulators are installed in vertical positions with porcelain tie tops that securely hold and support various conductor sizes.
Competitive Advantages
Superior Performance & Durability
High-aluminum porcelain construction provides smaller core diameter with exceptional mechanical strength, resulting in reduced unit weight for easier installation and maintenance.
Extended Service Life
Porcelain line post insulators outperform silicone rubber alternatives with significantly longer service life and zero maintenance requirements.
Quality Assurance
Comprehensive 3 to 5-year quality guarantee backed by smooth, shining glaze with excellent self-cleaning properties for minimal maintenance.
Custom Solutions
We offer custom insulator design services to meet specific customer requirements and technical specifications.
