<p>The present invention relates to grading devices (1) for reducing electrical stress in two or more electrically insulating members (29) of an electricity network tower. Preferably, a grading device (1) for reducing electrical stress in two or more electrically insulating members (29) of an electricity network tower, each electrically insulating member (29) having means for connecting the electrically insulating member (29) to an electrical power line supported by the electricity network tower, is provided, wherein: the grading device (1) includes two or more grading rings (3, 5, 7, 9), each of which is shaped so that in use it completely or substantially surrounds a respective one of the electrically insulating members (29); and the two or more grading rings (3, 5, 7, 9) are connected together.</p> |
