<p>A flexible electric power extension cable includes at least two conductors for electrical pipe processing equipment, a plug and a female cable connector part. The plug contains the at least two-conductors and is electrically connected to the front end of the electric power extension cable for receiving line power while geometrically fitting into a line-power electric outlet box. The female cable connector part contains the at least two conductors and is electrically connected to the rear end of the electric power extension cable. There is a mismatch between the geometry of the female cable connector part and that of the cable plug to preclude connection between the female cable connector part and the plug.</p> |
