    Frequently Asked Questions
    Q What is the maximum continuous operating temperature of this cable?
    The cable supports a continuous maximum temperature of 204 ℃ (400 °F). For short-duration applications, it can withstand up to 260 ℃ (500 °F) for 1 hour, or 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 (28,100 lbs). The maximum suggested working tension is 62.5 kN (14,050 lbs), which is 50% of the breaking strength, providing a standard safety factor for downhole operations.
    Q What voltage rating does this cable support?
    This cable is rated at 1200 VDC, making it suitable for high-voltage downhole measurement and logging tool applications. The insulation resistance is 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation.
    Q What type of insulation material is used, and what are its dimensions?
    The conductor insulation is made of FEP (Fluorinated Ethylene Propylene), with an outer diameter of 2.48 mm (0.0976"). FEP is chosen for its excellent high-temperature resistance, low dielectric constant, and chemical inertness in harsh downhole environments.
    Q What is the minimum shave (sheave) diameter required for this cable?
    The minimum sheave diameter for this cable is 576 mm (22.6"). Using a sheave smaller than this minimum can cause permanent deformation of the armor wires, reducing the cable's mechanical strength and service life.
    Q What is the conductor construction and how does it affect performance?
    The conductor uses a 7-wire stranded copper construction (7×0.36 mm). This stranded design provides greater flexibility compared to a solid conductor, improves resistance to fatigue from repeated spooling cycles, and maintains consistent electrical resistance of 26.5 Ω/km at 20 ℃.
