❓ Frequently Asked Questions
Q
What type of insulation material is used in this cable?
This cable uses FEP (Fluorinated Ethylene Propylene) and ETFE (Ethylene Tetrafluoroethylene) insulation, providing excellent thermal stability, chemical resistance, and electrical performance in demanding downhole environments.
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 204 ℃ (400 °F). For short-term operations, it can withstand up to 260 ℃ (500 °F) for 1 hour, and 232 ℃ (450 °F) for up to 8 hours.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a breaking strength of 125 kN (28,000 lbs). The maximum suggested working tension is 62.5 kN (14,050 lbs), which is 50% of the breaking strength, ensuring a safe operating margin during deployment.
Q
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 1200 VDC. Its insulation resistance is exceptionally high at 15,000 MΩ·km (50,000 MΩ·kft), ensuring minimal signal leakage and reliable electrical performance downhole.
Q
What is the minimum shave (sheave) diameter for this cable?
The minimum shave diameter is 600 mm (23.6"). Using a sheave smaller than this diameter may cause mechanical stress on the armor wires and reduce the cable's service life.
Q
What does the dual-armor construction offer compared to single-armor cables?
The dual-armor design features both an inner armor (22×1.11 mm, 2272 N breaking strength) and an outer armor (22×1.44 mm, 3825 N breaking strength). This provides significantly enhanced mechanical protection, higher tensile strength, and improved resistance to crushing and abrasion in high-pressure well environments.
