An electrical assembly having an elongated electrical component, such as a surge arrester, coupled to a grading device for distributing an electric field along the electrical component during operation. The grading device includes a grading body and a means for securing the grading body to the electrical component. The grading body, the securing means, or both include semi-conductive materials. The semi-conductive materials can be nonmetallic. The grading device has improved flashover resistance over conventional metal grading devices. |
