Frequently Asked Questions
Q
What type of insulation is used in this cable, and why is it suitable for high-temperature environments?
This cable uses PFA (Perfluoroalkoxy) insulation with a diameter of 2.64 mm. PFA is a high-performance fluoropolymer known for its excellent thermal stability, chemical resistance, and electrical properties. It supports continuous operation up to 246 ℃ (480 °F), making it ideal for demanding downhole and high-temperature industrial applications.
Q
What is the maximum operating temperature for this cable?
The cable supports three temperature ratings: a 1-hour maximum of 280 ℃ (540 °F), an 8-hour maximum of 260 ℃ (500 °F), and a continuous maximum operating temperature of 246 ℃ (480 °F). Always select the appropriate rating based on your application's duty cycle and thermal profile.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a total breaking strength of 20 kN (4,500 lbs). The maximum suggested working tension is 10 kN (2,250 lbs), which represents 50% of the breaking strength — a safety margin designed to ensure long-term mechanical integrity during installation and operation.
Q
What is the voltage rating and insulation resistance of this cable?
The cable is rated for 1200 VDC. Its insulation resistance is exceptionally high at 15,000 MΩ·km (50,000 MΩ·kft), ensuring minimal leakage current and reliable electrical signal transmission even in harsh, high-pressure downhole environments.
Q
What is the minimum sheave (pulley) diameter required for this cable?
The minimum sheave diameter for this cable is 320 mm (13 inches). Using a sheave smaller than this minimum can cause excessive bending stress on the armor wires and conductor, potentially leading to premature fatigue failure or damage to the insulation layer.
Q
How is the double-armor construction beneficial compared to single-armor cables?
The double-armor construction — with an inner armor of 12 × 0.79 mm wires and an outer armor of 18 × 0.79 mm wires — provides significantly enhanced crush resistance, torque balance, and tensile strength. Each armor layer contributes an average wire breaking strength of 867 N (195 lbs), resulting in superior protection during deployment in deep wells or mechanically challenging environments.
