Using the anti-icing transmission line of electricity 3 of passive-type of the invention, 3 ontology of transmission line of electricity is covered by de-icer boot, is encountered in winter
When rain and snow weather, rain or snow can only be fallen on de-icer boot.Card is set upper anti-icing card slot 12 on de-icer boot in anti-icing card slot 13 under
Anti-freezing agent block contacted with sleet, the freezing point of water reduces (would generally be reduced to subzero 20 DEG C or so).Due to coming for ice and snow
It says, actually the process melted and solidified constantly occurs for its surface, because melting the (speed of thawing equal with the speed of solidification
