Abstract
The invention relates to a spark protection device for insulated conductors, particularly for overhead lines, having a housing consisting of a base part (5) and a cover part (6) which are clamped to one another by means of clamping elements (15) and which housing has fast jaws (7, 8) between which the conductor to be protected is clamped. At least one jaw is provided with teeth (9, 10) whose length corresponds at least to the thickness of the insulation of the conductor to be protected. Between a second pair of jaws (11; 12, 13) there is arranged a spark arrester horn (2) which extends away from the spark protection device and whose distance from the conductor to be protected is adequate to keep an electrical spark away from the wire. <IMAGE>
