Frequently Asked Questions
Q1
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 204 °C (400 °F). For short-duration exposure, it can withstand up to 260 °C (500 °F) for 1 hour and 232 °C (450 °F) for 8 hours, making it suitable for high-temperature downhole environments.
Q2
What is the cable's maximum breaking strength and recommended working tension?
The cable has a total breaking strength of 66 kN (15,000 lbs). The maximum suggested working tension is 33 kN (7,500 lbs), which is 50% of the breaking strength, ensuring a safe operating margin during deployment and retrieval operations.
Q3
What insulation materials are used, and why are FEP and ETFE chosen?
This cable uses both FEP (Fluorinated Ethylene Propylene) and ETFE (Ethylene Tetrafluoroethylene) insulation layers. These fluoropolymer materials offer excellent chemical resistance, high-temperature stability, and superior electrical insulation properties, making them ideal for harsh downhole oil and gas well environments.
Q4
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 1500 VDC with an insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft). This high insulation resistance ensures minimal signal leakage and reliable electrical performance during logging and monitoring operations in deep wells.
Q5
What is the double-armor construction design and what are its benefits?
The cable features a double-armor design with an inner armor of 12×1.11 mm wires and an outer armor of 18×1.11 mm wires. Each armor layer provides an average wire breaking strength of 2,514 N (565 lbs). This dual-layer construction significantly enhances crush resistance, tensile strength, and protection against mechanical damage during deployment in deep wellbores.
Q6
What is the minimum shave (sheave) diameter requirement for this cable?
The minimum sheave (shave) diameter for this cable is 600 mm (23.6"). Using a sheave below this minimum diameter may cause excessive bending stress on the armor wires and conductor, potentially reducing the cable's service life or causing premature failure. Always ensure compatible winch and sheave equipment is used during field operations.
