GW4B-6.35 Multi-Core Steel Tube Cable utilizes seamless metal sleeve made of 316L stainless steel and 825 high-corrosion-resistant nickel-iron-chromium alloy to enclose multiple independent copper conductors. It operates steadily from -40℃ to 260℃ and bears maximum working pressure up to 30000 psi, serving as standard-size High Temperature Steel Tube Cable for oil & gas well monitoring systems. This product builds full-coverage downhole data acquisition network with Well Logging Cable and continuously collects real-time operating parameters of electric submersible pumps alongside ESP Submersible Pump Cable. Each internal signal circuit is isolated separately. The sealed outer metal shell prevents corrosion induced by hydrogen sulfide, crude oil and formation wastewater, and it can be integrated with Hydraulic Control Capillary Tubing to form complete downhole measurement and control pipelines.
With an outer diameter of 6.35mm, GW4B-6.35 features compact and lightweight constructi…
