Frequently Asked Questions
Q1
What is the copper construction used in this cable?
The cable uses a 7-strand copper conductor with each wire measuring 0.21 mm (0.0082") in diameter, providing a reliable and flexible conductive core suitable for downhole logging applications.
Q2
What are the maximum operating temperatures for this cable?
This cable supports three temperature ratings depending on exposure duration: 150 °C (300 °F) for up to 1 hour, 135 °C (275 °F) for up to 8 hours, and a continuous maximum of 121 °C (250 °F). These ratings help ensure safe and reliable performance across various well conditions.
Q3
What is the cable breaking strength and recommended working tension?
The cable has a total breaking strength of 8 kN (1,800 lbs). The maximum suggested working tension is 4 kN (900 lbs), which is 50% of the breaking strength — a standard safety margin for wireline operations to prevent permanent deformation or failure.
Q4
What is the voltage rating and insulation resistance of the cable?
The cable is rated at 300 VDC and offers an exceptionally high insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation even under demanding downhole environments.
Q5
What is the minimum sheave (shave) diameter required for this cable?
The minimum sheave diameter for this cable is 190 mm (7.5"). Using a sheave smaller than this specification can cause excessive bending stress on the armor wires and conductor, potentially leading to premature fatigue and cable failure.
Q6
How is the cable's stretch coefficient defined, and why does it matter?
The cable stretch coefficient is 7.3 m/km per 5 kN of tension (6.5 ft/kft/klbs). This parameter is critical for accurate depth measurement in wireline logging operations — a higher stretch coefficient means greater depth correction calculations are required at increased working tensions.
