Self-melting insulating tape wrapping intermediate joint manufacturing process

The invention relates to a self-melting insulating tape wrapping intermediate joint manufacturing process, which comprises the following steps: S1, cable pretreatment and cable core connection: removing outer sheaths, armor layers, inner sheaths, copper shielding layers, outer semi-conductive layers, main insulating layers and inner semi-conductive layers of two sections of cables to be connected, and connecting cable cores of the two sections of cables by using a connecting pipe, S2, recovering the inner semi-conductive layer; S3, performing plasma treatment on the outer surface of the front end of the main insulating layer and manufacturing a cable joint; and S4, performing waterproof and mechanical protection treatment on the cable. the main insulating layer is made of a cross-linked polyethylene material. According to the invention, the self-melting insulating tape layer is used for wrapping, a special heating device and a plasma corona machine are not needed to carry out a plasma treatment technology on
