The 6.55 mm mono conductor wireline cable is an armored downhole cable for logging, intervention, and other well-service operations that require an electrical conductor and high tensile strength in one compact construction. Its 16 AWG stranded conductor sits inside insulation, a 12-wire inner armor layer, and an 18-wire outer armor layer. TEBAOFLEX can support configuration review for the operating environment and insulation temperature requirement.
Key Features
- 16 AWG stranded center conductor with a 1.499 mm nominal conductor diameter.
- Two-layer steel armor construction with 12 inner wires and 18 outer wires, each specified at 0.0358 in.
- 1200 VDC rating and 457 MΩ·km minimum insulation resistance in the conventional construction data.
- 6.55 mm nominal outside diameter for compact handling on suitable downhole sheaves.
- Multiple insulation options with stated temperature ratings from 149 °C to 315 °C, depending on selected construction.
Applications
This mono conductor wireline cable is suited to downhole operations where a single electrical path and armored mechanical support are required. Confirm the selected insulation system, operational temperature, loading, fluid exposure, and sheave arrangement before specification.
Documented Construction Specifications
The referenced construction uses a 16 AWG, 19-strand center conductor with a 1.499 mm nominal conductor diameter. Its insulation outside diameter is 3.124 mm, followed by 12 inner armor wires and 18 outer armor wires, each specified at 0.0358 in. The conventional configuration is rated 1200 VDC and has a 6.55 mm nominal outside diameter.
