Frequently Asked Questions
Q
What type of insulation material is used in this cable, and why?
This cable uses Polypropylene (PP) insulation with a diameter of 3.81 mm (0.1496"). PP insulation is widely chosen for downhole and logging cables due to its excellent thermal stability, chemical resistance, and reliable dielectric properties in high-temperature environments.
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 121 ℃ (250 °F). For short-term operations, it can withstand up to 135 ℃ (275 °F) for 8 hours, and up to 150 ℃ (300 °F) for 1 hour, making it suitable for a range of downhole thermal conditions.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a breaking strength of 55 kN (12,300 lbs). The maximum suggested working tension is 27.5 kN (6,150 lbs), which is 50% of the breaking strength — a standard safety factor applied in oilfield logging and intervention operations to ensure cable integrity during deployment.
Q
What voltage and insulation resistance ratings does this cable offer?
The cable is rated at 1500 VDC. Its insulation resistance is 15,000 MΩ·km (50,000 MΩ·kft), indicating extremely high electrical isolation performance that is critical for accurate signal transmission and safety in downhole logging applications.
Q
What is the minimum shave (sheave) diameter required for this cable?
The minimum sheave diameter for this cable is 450 mm (18"). Using a sheave smaller than this can cause excessive bending stress, leading to conductor fatigue, armor wire damage, or premature cable failure. Always ensure your surface equipment meets this specification.
Q
How does the dual-armor construction enhance cable performance?
The cable features both an inner armor (12 × 1.11 mm wires) and an outer armor (18 × 1.11 mm wires), each with an average wire breaking strength of 1970 N (442 lbs). This double-armor design provides enhanced mechanical protection against crushing, abrasion, and tensile loads encountered in deep wellbore environments, significantly extending service life.
