A miniature photoelectric composite cable for high-definition video signal transmission includes a flat optical fiber component and a round electrical component. The flat optical fiber component includes a multi-core optical fiber, a strengthening layer, and a light jacket. The round electrical component includes a multi-core electrical cable, a cladding, and an electric jacket. The cladding covers outside the multi-core electrical cable. The optical fiber component and the electrical component are arranged side-by-side.

Disclosed are cable types, including a type THHN cable, the cable types having a reduced surface coefficient of friction, and the method of manufacture thereof, in which the central conductor core and insulating layer are surrounded by a material containing nylon or thermosetting resin. A silicone based pulling lubricant for said cable, or alternatively, erucamide or stearyl erucamide for small cable gauge wire, is incorporated, by alternate methods, with the resin material from which the outer sheath is extruded, and is effective to reduce the required pulling force between the formed cable and a conduit during installation.
