    Frequently Asked Questions
    Q What is the maximum operating temperature for this cable?
    This cable supports three temperature ratings depending on duration: 260 ℃ (500 °F) for up to 1 hour, 232 ℃ (450 °F) for up to 8 hours, and a continuous maximum of 204 ℃ (400 °F). Always select the appropriate rating based on your application's thermal demands.
    Q What is the voltage rating of this cable?
    The cable is rated at 1200 VDC, making it suitable for high-voltage downhole and subsurface applications where reliable DC power transmission is required.
    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 — a standard safety factor for oilfield cable operations.
    Q What type of insulation material is used in this cable?
    The cable uses FEP (Fluorinated Ethylene Propylene) insulation with a diameter of 2.48 mm (0.0976"). FEP offers excellent chemical resistance, high-temperature performance, and low dielectric loss, making it ideal for demanding downhole environments.
    Q What is the minimum shave diameter for this cable?
    The minimum shave (sheave) diameter is 576 mm (22.6"). Using a sheave smaller than this specification may cause mechanical damage to the armor or conductor, reducing the cable's service life and structural integrity.
    Q What are the armor wire specifications for inner and outer armor?
    The inner armor consists of 22 wires at 1.11 mm (0.0437") diameter each, with an average breaking strength of 2,273 N (511 lbs) per wire. The outer armor consists of 22 wires at 1.44 mm (0.0566") diameter each, with an average breaking strength of 3,825 N (860 lbs) per wire, providing robust mechanical protection in high-tension deployments.
