What is the maximum operating temperature for this cable?
The cable supports three temperature ratings depending on duration: 260 ℃ (500 °F) for 1 hour, 232 ℃ (450 °F) for 8 hours, and a continuous maximum operating temperature of 204 ℃ (400 °F). The FEP insulation is specifically selected to maintain integrity at these elevated temperatures.
What is the cable's breaking strength and recommended working tension?
The cable has a total breaking strength of 125 kN (28,100 lbs). The maximum suggested working tension is 62.5 kN (14,050 lbs), which is exactly 50% of the breaking strength — a standard safety factor applied in downhole and wireline operations.
What type of insulation is used, and why is FEP chosen?
The conductor uses FEP (Fluorinated Ethylene Propylene) insulation with a diameter of 2.48 mm. FEP is chosen for its excellent high-temperature resistance, low dielectric constant, chemical inertness, and superior electrical insulation properties — making it ideal for demanding downhole environments.
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 1200 VDC. The insulation resistance is exceptionally high at 15,000 MΩ·km (50,000 MΩ·kft), ensuring minimal signal leakage and reliable electrical performance even under high-temperature and high-pressure downhole conditions.
What is the difference between the inner and outer armor layers?
Both armor layers consist of 22 wires each. The inner armor uses 1.11 mm wires with a breaking strength of 2,273 N (511 lbs) per wire, while the outer armor uses larger 1.44 mm wires with a higher breaking strength of 3,825 N (860 lbs) per wire. The dual-armor design provides enhanced mechanical protection and tensile strength.
What is the minimum shave diameter and why does it matter?
The minimum shave (sheave) diameter is 576 mm (22.6"). This specification defines the smallest diameter pulley or wheel over which the cable can be safely bent without causing damage to the armor wires or internal conductors. Using a sheave smaller than this minimum can lead to permanent deformation, reduced breaking strength, or electrical failure.
