• Detailed Product Introduction

• Downhole logging cables have to carry electrical signals while being handled, deployed and retrieved in a demanding well environment. A compact cable construction can be useful where available space is limited, while the outer protection needs to support the mechanical requirements of the operation. The GG1F46-4.0 1×0.56 uses a stranded soft copper conductor at its center. The conductor specification is 7 × 0.32 mm. Around the conductor is a 0.60 mm F46 insulation layer, followed by two 316L stainless steel tube layers. The inner stainless steel tube has a specified wall thickness of 0.30 mm, and the outer tube has a specified wall thickness of 0.40 mm. This layered construction forms the cable's compact armored body. The finished cable has a nominal diameter of 4.0 mm ± 0.05 mm and a weight in air of 79 kg/km. The specified operating temperature range is -50°C to +232°C, while the specified tensile strength is 7 kN. For electrical performance, the cable is specified for a 300 VDC withstand voltage. At 20°C, insulation resistance is ≥500 MΩ·km and DC resistance is ≤33 Ω/km. The specified capacitance is ≤0.16 μF/km.

Key Features

• Single-Core Construction
• A single stranded copper conductor forms the electrical core, providing a straightforward signal and power path within the armored structure.
• F46 Insulation
• The conductor is surrounded by an F46 insulation layer with a specified thickness of 0.60 mm.
• Dual 316L Stainless Steel Tube Layers
