A tape wrapping device adapted to wind a tape with an adhesive surface and a back surface on a product includes a seat frame, and a tape conveying mechanism installed on the seat frame and adapted to convey the tape to a standby position. The tape conveying system includes a first conveying drum positioned upstream of the standby position along a conveying direction. An outer contour defining an outer peripheral surface of the first conveying drum has a variable outer diameter along an axial direction and is adapted to convey the tape towards the standby position when its outer peripheral surface is in contact with one of the adhesive surface and the back surface of the tape. A binding mechanism is configured to wrap the tape on the product when the product is bonded to the tape at the standby position.

A power cable has a cable core comprising at least one conductor with an insulating system and a water barrier surrounding the cable core. The water barrier comprises a helically wound strength bearing layer interconnected by a low melting point material.
