AC disc type suspension porcelain insulator
AC disc type suspension porcelain insulator-(disc cap-nail type) is the main product for overhead power transmission. It has three shed profiles: ordinary, anti-fog, and anti-fouling. It is type tested according to IEC 60305 / IEC 60383 and undergoes 100% routine electromechanical testing. Strings can be configured from 33 kV to 1000 kV ACs. Optional zinc ring for marine and industrial environments.
Disc suspension insulators for AC transmission lines.
- 70-530 kN Electromechanical load level
- Standard, anti-fog (BP), anti-fouling shed profile
- Optional zinc ring for corrosion corridor
- Complies with IEC 60305 / 60383 / 60797
