20/24kV，Adopting composite material silicone rubber, the surface of the columnar body is designed with corrugated structure to increase creepage distance and block sewage flow. Some models use solid ceramic parts combined with metal flange structure, Suitable for three-phase AC 50Hz distribution systems, suitable for substations, industrial distribution and other scenarios, vertical pillar type: flange fixed, supporting busbar support or equipment insulation isolation.
| Product model | Rated voltage（KV） | Rated bending load（KN） | Structure hight (mm) | Minimum arc distance(mm) | Minimum creepage distance (mm) | Lightning impulse voltage (peak) (KV) | 1 min power frequency wet voltage (KV) |
| FZSW-20/4 | 20/24 | 4 | 350 | 320 | 750 | 130 | 900 |
