Product Overview
W1B-5.61×1.0 Single-Core Logging Cable is a single-conductor armored wireline cable specifically designed for oil and gas well logging operations. The cable structure combines a central electrical conductor with high-strength steel wire armor to provide both reliable data transmission and superior mechanical performance in harsh downhole environments.
Technical Description
Logging Cable W1B-5.61×1.0 Single-core Logging Cable
W1B-5.61×1.0 refers to a specialized, single-conductor armored geophysical well logging cable. These electro-mechanical wirelines are heavily used in oilfields, mining, and water drilling to lower subsurface measurement probes (tools) and transmit.
Cable Construction
- Conductor
- Single-core stranded copper conductor
- Cross-sectional area: 1.0 mm²
- Provides stable electrical signal and power transmission with low resistance.
- Insulation Layer
- High-temperature resistant polypropylene (PP), FEP, ETFE, or customized insulation material.
- Provides excellent dielectric performance and protects the conductor from high temperature, pressure, and corrosive fluids.
- Bedding / Cushion Layer
- Special protective layer applied over the insulation.
- Enhances mechanical protection and improves cable flexibility.
- Inner Armor Layer
- First layer of high-strength galvanized steel wires.
- Provides tensile strength and impact resistance.
- Outer Armor Layer
- Second layer of high-strength galvanized steel wires wound in the opposite direction.
- Increases crushing resistance, torque balance, and overall mechanical durability.
- Cable Outer Diameter
- Nominal diameter: 5.61 mm
