Abstract

See full text

A top entry electrical transmission safety assembly for removably effecting electrical communication through a tubing hanger, between an above ground electric power supply cable and an electric power receiving cable that extends upwardly from a motor driven submersible pump in a bore hole. The electric power supply portion of the assembly may be removed from the tubing hanger without removing the latter from a supporting well head. The supporting well head has a bonnet removably secured thereto through which the electric power supply cable extends, which bonnet not only serves its normal function, but acts in a safety capacity to prevent the electrical transmission assembly being uncoupled inadvertently to create an electric arc or spark in a hazardous potentially explosive area such as on an off shore platform or island. The electrical transmission assembly can only be uncoupled after the electric power supply cable has been disconnected from the source of electric power; the electric power supply cable disengaged from the bonnet; and the bonnet removed from the well head.
