FIELD: oil and gas industry.
SUBSTANCE: invention is referred to the oil and gas industry and may be used for the protection of the power cable for a pump from mechanical damage in the process of the tubing hanger trip with the installation of an electric centrifugal pump in vertical, directional and horizontal wells. A protectoliser is suggested that consists of a two-component case, a detachable tool joint with fastening elements and a protecting screen. The case consists of an articulated case and a bracket. The protectoliser case and bracket are interconnected by a swing bolt and an adjusting screw screwed into the case and connected to the bracket by an axle. The adjusting screw may be regulated axially due to screwing in/out into/from the case when the diameter of the pump neck changes. The protectoliser case in a cable duct is complete with a replaceable plate fixed at the case by two screws. The detachable tool joint is made as a hinged bolt and a hold-down nut with a spring lock to prevent uncontrolled turning off.
EFFECT: improving the reliability of the protectoliser fixation at the pump neck; improved universality of the protector.
