Detailed description of the invention
In order to make this utility model purpose, technical scheme and advantage clearer, below in conjunction with the accompanying drawings with embodiment to this
Utility model is described in further detail.
Embodiment of the present utility model: structural representation such as Fig. 1 institute of high-voltage power line line conductor spontaneous heating deicing device
Showing, including ice-melt wire and device for monitoring icing, see Fig. 2, described ice-melt wire is by wire-core 1 and to be wrapped in steel wire
4 layers of aluminum conductor 2 on core 1 are constituted, and are wound with two root table topcoating in the innermost layer of aluminum conductor 2 along the winding direction of aluminum conductor 2
The inner conductor 3 of insullac, the secondary outer layer at aluminum conductor 2 is wound with the two root table topcoating contrary with inner conductor 3 winding direction
