Frequently Asked Questions
Q
What type of insulation is used in this cable, and why is PFA preferred?
This cable uses PFA (Perfluoroalkoxy) insulation with an outer diameter of 2.76 mm. PFA is preferred in downhole logging cables because of its exceptional thermal stability, chemical resistance, and ability to maintain electrical integrity at continuous temperatures up to 246 °C (480 °F), making it ideal for high-temperature well environments.
Q
What is the maximum operating temperature of this cable?
The cable supports three temperature ratings: a continuous maximum of 246 °C (480 °F), an 8-hour maximum of 260 °C (500 °F), and a 1-hour peak of 280 °C (540 °F). These ratings allow the cable to handle both prolonged and short-term exposure to extreme downhole heat conditions.
Q
What is the cable's breaking strength, and what is the recommended working tension?
The cable has a total breaking strength of 30 kN (6,700 lbs). For safe operational use, the maximum suggested working tension is 15 kN (3,350 lbs), which represents a 2:1 safety factor to protect the cable from premature mechanical failure during logging operations.
Q
What voltage and insulation resistance ratings does this cable carry?
The cable is rated at 1200 VDC, suitable for standard wireline power and signal transmission. Its insulation resistance is 15,000 MΩ·km (50,000 MΩ·kft), indicating excellent dielectric performance that minimizes signal leakage and ensures reliable communication between surface equipment and downhole tools.
Q
What is the minimum sheave diameter required for this cable?
The minimum sheave (pulley) diameter for this cable is 320 mm (13 inches). Using sheaves smaller than this limit can cause excessive bending stress on both the armor wires and the internal conductor, potentially leading to mechanical damage or reduced service life.
Q
How is the dual-armor construction beneficial for wireline operations?
The dual-armor design features an inner armor layer (15×0.61 mm, 600 N avg. breaking strength) and a stronger outer armor layer (15×0.89 mm, 1,300 N avg. breaking strength). This configuration provides layered mechanical protection against tension, abrasion, and wellbore pressure, significantly extending the cable's operational lifespan in demanding downhole environments.
