Frequently Asked Questions
Q
What is the cable breaking strength and safe working tension?
The cable has a breaking strength of 25 kN (5,600 lbs). The maximum suggested working tension is 12.5 kN (2,800 lbs), which is 50% of the breaking strength — a standard safety factor for downhole cable applications.
Q
What are the maximum operating temperatures for this cable?
The cable supports three temperature ratings depending on exposure duration: 150 ℃ (300 °F) for up to 1 hour, 135 ℃ (275 °F) for up to 8 hours, and 121 ℃ (250 °F) for continuous operation.
Q
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 200 VDC. Its insulation resistance is 15,000 MΩ·km (50,000 MΩ·kft), indicating excellent dielectric performance suitable for demanding downhole logging environments.
Q
What armor construction does this cable use?
The cable features a dual-armor design: an inner armor of 12 × 0.79 mm wires and an outer armor of 18 × 0.79 mm wires. Each armor wire has an average breaking strength of 916 N (206 lbs), providing robust mechanical protection.
Q
What is the minimum shave (sheave) diameter required for this cable?
The minimum sheave diameter for this cable is 320 mm (13 inches). Using a sheave smaller than this limit may cause excessive bending stress and could damage the armor or conductor over time.
Q
What is the cable stretch coefficient and why does it matter?
The cable stretch coefficient is 2.5 m/km per 5 kN of applied tension (2.2 ft/kft/klbs). This value is critical for depth accuracy during wireline logging operations, as it allows engineers to calculate and compensate for cable elongation under load.
