Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 204 °C (400 °F). For short-term operation, it can withstand up to 260 °C (500 °F) for 1 hour and 232 °C (450 °F) for 8 hours.
Q
What is the cable's voltage rating and insulation resistance?
The cable is rated at 1000 VDC. Its insulation resistance is 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation in demanding downhole environments.
Q
What is the maximum suggested working tension for this cable?
The maximum suggested working tension is 58.5 kN (13,150 lbs), which is 50% of the cable's total breaking strength of 117 kN (26,300 lbs).
Q
Why is FEP used as the insulation material?
FEP (Fluorinated Ethylene Propylene) provides outstanding high-temperature resistance, excellent chemical compatibility, and superior electrical insulation properties, making it ideal for oil well and downhole cable applications.
Q
What are the armor wire breaking strengths for the inner and outer layers?
The inner armor has an average wire breaking strength of 2,041 N (459 lbs), while the outer armor provides a higher breaking strength of 3,240 N (729 lbs), together contributing to the cable's overall mechanical durability.
Q
What is the minimum shave diameter and why does it matter?
The minimum shave (sheave) diameter is 600 mm (23.6"). This specification is critical for installation and deployment — using a sheave smaller than the recommended diameter can cause permanent deformation or damage to the armor wires, reducing the cable's service life and tensile performance.
