The 8.89 mm Armored Downhole Wireline Cable is an armored electrical cable for downhole logging, intervention, and well-service applications. Its construction combines a stranded copper conductor, insulation, and two mechanical armor layers to carry an electrical signal while supporting controlled deployment in the well. TEBAOFLEX can review the required load, sheave diameter, temperature, fluid exposure, and length before configuration selection.
Key Features
- Armored mono conductor construction for electrical continuity and mechanical support.
- Specified voltage, resistance, and tensile data for the documented configuration.
- Multiple insulation options where stated in the technical data, allowing selection by temperature requirement.
- Suitable for controlled wireline deployment where the selected load and sheave arrangement remain within the documented limits.
Downhole Application
Wireline systems are used to lower and retrieve downhole tools while providing a reliable electrical path. Installation should follow the selected cable’s documented load limits, bend guidance, and environmental requirements.
