About the Porcelain Station Post Insulator
Porcelain station post insulators according to IEC, ANSI and other standards are used in substations and related switching equipment. They are produced in single piece up to 2300 mm and can operate voltages up to 1100KV in stacked configuration. Post insulators are subjected to compression, cantilever and torsional loads during service.
Advantages of porcelain station post insulator
1. This porcelain station post insulator is produced with advanced isostatic pressing dry-forming technology
2. This porcelain post insulator has high bending strength load,which is enable to keep stability under sever natual circumstance.
3. The surface of this porcelain station post insulator has perfect glaze, which can be made into light grey or brown according to your requirement.
Pecifications
1.Certificated by IEC ANSI GB ISO9001
