Abstract

Electric overhead cables which are drawn through forests suffer from the fact that the cut outs, so called cable lanes, tend to grow over resulting in disturbances when the trees are bent down by snow so as to contact the cables. The problem can be essentially diminished by using insulated cables, but to replace existing cables is very expensive. The invention provides a method and a device for insulating overhead cables on the spot by enclosing them with an insulating plastic covering. It is mainly characterized by a carriage which is movable on the cable and which includes means (30, 41, 42) for successively laying a plastic band onto the cable, a heating element (43) for heating the edge portions of the band and a clamping device (20, 21, 22) for continuously pressing together and welding the heated band edges while enclosing the cable.
