    Frequently Asked Questions
    What type of insulation materials are used in this cable?
    This cable is available with two insulation options: FEP (Fluorinated Ethylene Propylene) with a diameter of 1.65 mm (0.0649") and ETFE (Ethylene Tetrafluoroethylene) with a diameter of 2.13 mm (0.0838"). Both materials offer excellent thermal and chemical resistance for demanding downhole environments.
    What is the maximum operating temperature of this cable?
    The cable supports three temperature ratings depending on duration: 260 °C (500 °F) for up to 1 hour, 232 °C (450 °F) for up to 8 hours, and a continuous maximum operating temperature of 204 °C (400 °F).
    What is the cable's breaking strength and recommended working tension?
    The cable has a total breaking strength of 109 kN (24,500 lbs). The maximum suggested working tension is 54.5 kN (12,250 lbs), which is 50% of the breaking strength — a standard safety factor for reliable field operations.
    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 leakage current and reliable signal integrity in high-temperature downhole conditions.
    What is the minimum sheave (pulley) diameter required for this cable?
    The minimum sheave diameter for safe cable operation is 670 mm (26.4"). Using a sheave smaller than this specification may cause permanent deformation or damage to the armor wires and internal conductors.
    What do the inner and outer armor specifications mean?
    The inner armor consists of 18 wires × 1.19 mm diameter with an average breaking strength of 2,170 N (488 lbs) per wire, while the outer armor consists of 18 wires × 1.66 mm diameter with a breaking strength of 4,220 N (948 lbs) per wire. This dual-armor construction provides robust mechanical protection against tension, crushing, and abrasion in wellbore operations.
