    Frequently Asked Questions
    Q What insulation and protection materials are used in this cable?
    This cable uses PFA (Perfluoroalkoxy) as the primary insulation layer with a diameter of 2.04 mm (0.0803″), and ETFE (Ethylene Tetrafluoroethylene) as the outer protection layer with a diameter of 2.64 mm (0.1039″). Both materials offer excellent high-temperature resistance and chemical durability.
    Q What is the maximum continuous operating temperature of this cable?
    The cable supports a continuous maximum temperature of 204 ℃ (400 ℉). For short-duration exposure, it can withstand up to 232 ℃ (450 ℉) for 8 hours and up to 260 ℃ (500 ℉) for 1 hour, making it suitable for demanding high-temperature downhole environments.
    Q What is the cable's breaking strength and recommended working tension?
    The cable has a breaking strength of 22 kN (4,950 lbs). The maximum suggested working tension is 11 kN (2,475 lbs), which is exactly 50% of the breaking strength — in line with standard industry safety factors for downhole cable deployment.
    Q What voltage rating does this cable support?
    This cable is rated for 1200 VDC. It also offers an insulation resistance of 15,000 MΩ·km (metric) or 50,000 MΩ·kft (imperial), ensuring reliable electrical isolation even in harsh downhole conditions.
    Q How is the armor construction designed for this cable?
    The cable features a dual-armor design: an inner armor layer of 12×0.79 mm wires (867N / 195 lbs each) and an outer armor layer of 18×0.79 mm wires (867N / 195 lbs each). This configuration provides enhanced mechanical protection and tensile strength suitable for deep well applications.
    Q What is the minimum shave diameter and why does it matter?
    The minimum shave (sheave) diameter for this cable is 320 mm (13″). Using a sheave smaller than this minimum can cause excessive bending stress, which may damage the armor wires, insulation, or conductor strands and reduce the cable's service life. Always ensure that all downhole and surface equipment meets or exceeds this specification.
