DEVICE FOR POWER CABLE CONNECTION TO TUBING STRING Russian patent published in 2005 - IPC

Abstract RU 2266385 C1

FIELD: obtaining oil, gas, water, soluble or meltable materials or a slurry of minerals from wells, particularly safety devices to protect power cables of submersed electric motors used to drive centrifugal pumps.

SUBSTANCE: device comprises body retained from longitudinal movement at upper and lower coupler ends, two caps arranged in upper and lower body parts. Each cap has hinge and screw to press the cap and body to power string. Body surface is made as a cylinder, which passes into longitudinal walls at upper and lower ends thereof. The longitudinal walls form coaxial longitudinal grooves for cable laying. Flanges with through orifices for screw receiving are arranged from one groove side. The screws being assembled with hinge pins secured to the first cap ends to form screw pairs. Cap engaging means are created from another groove side. The caps are elastodeformed and cap thickness does not exceed coupler wall thickness. The caps are provided with members mating above cap engaging members made at free ends thereof. Body is formed so that in assembled state cylindrical surface thereof extends beyond the flanges and the cap engaging members. Inner ends of longitudinal walls are adapted to fix the device at upper and lower coupler ends.

EFFECT: increased efficiency of power cable protection against impact action, reduced weight and size.
