Line Post Porcelain Insulators
Line post porcelain insulators are mounted as cantilever posts, eliminating string swing for compact line designs. The R-series complies with IEC 60720 and supports horizontal, vertical and braced post configurations from 35 kV through 220 kV.
Post-style insulators for compact transmission designs.
- Cantilever loads from 3 to 20 kN
- Voltage classes 35 / 66 / 110 / 220 kV
- Horizontal, vertical, braced configurations
- IEC 60720 type-tested
