Lysbue-beskyttelsesanordning for mellomspennings-kabler med kledning

摘要

The invention relates to an arching protection device for coated medium-voltage cables. Each wire (3) is fitted with arc conductors (4) by means of clamps (5), which are provided with wire-insulator piercing teeth (14). A second number of arc conductors (6) are attached to a crossarm (2) by way of a flat-iron bracket or a like holder element (7). An adjustable arc gap results between the arc conductors (4 and 6). Thus, the arc discharges produced by overvoltages do not damage the wire.
