G3F-21 Multi-Conductor Steel Tube Cable adopts sealed sleeve composed of 316L stainless steel and 825 high-corrosion-resistant nickel-iron-chromium alloy to encapsulate multiple copper conductors. It stably operates from -40℃ to 260℃ and withstands maximum working pressure up to 30000 psi, serving as large-diameter High Temperature Steel Tube Cable specially developed for deep oil & gas well exploitation. This product builds comprehensive downhole data acquisition network with Well Logging Cable and collects real-time operating parameters of electric submersible pumps alongside ESP Submersible Pump Cable. Multiple independent signal conductors are arranged inside the cable. The metal outer shell prevents corrosion caused by hydrogen sulfide, crude oil and formation wastewater, and it can be matched with Hydraulic Control Capillary Tubing to construct integrated downhole measurement and control pipelines.
As a large-size multi-conductor model, G3F-21 connects with Composite Coiled…
