Peeling method of insulated lead of distribution wire and peeling knife thereof

The invention relates to a peeling method of an insulated lead of a distribution wire and a peeling knife thereof. The peeling method adopts a jaw vice-shaped peeling knife, wherein the inside of a knife block of the peeling knife is provided with an upper knife block and a lower knife block which are arranged oppositely in vertical direction and can move relatively; symmetrical cambered concave cutting knife edges are formed on the side mouths of both knife blocks; the inner side of each knife block is provided with a single cutting knife edge; the cutting knife edges are connected with an electric hot plate to perform direct-current preheating for 8 to 10 minutes, and the temperature is controlled between 95 and 125 DEG C; and finally, the cutting knife edges are sleeved on a to-be-peeled insulated lead and are fed simultaneously through screwing a handle to cut in an insulation layer of the insulated lead and peel off the insulation layer. The peeling method has the advantages thatthe method not only impro
