    Frequently Asked Questions
    Q What is the cable breaking strength and maximum working tension of this cable?
    The cable has a 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 downhole cable applications.
    Q What are the maximum temperature ratings for this cable?
    This cable supports three temperature ratings depending on exposure duration: 150 ℃ (300 °F) for 1-hour peak exposure, 135 ℃ (275 °F) for 8-hour operation, and 121 ℃ (250 °F) for continuous long-term use.
    Q What type of insulation is used, and what is its diameter?
    The cable uses Polypropylene (PP) insulation with a diameter of 2.13 mm (0.0838"). PP insulation provides excellent dielectric properties and chemical resistance suitable for downhole environments.
    Q What is the voltage rating and insulation resistance of this cable?
    The cable is rated at 1200 VDC. It offers an insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation and reliability in high-pressure downhole conditions.
    Q What is the difference between the inner armor and outer armor in terms of construction and strength?
    The inner armor consists of 18 wires at 1.19 mm diameter each, with an average wire breaking strength of 2,170 N (488 lbs). The outer armor uses 18 wires at 1.66 mm diameter, with a significantly higher breaking strength of 4,220 N (948 lbs) per wire, providing the primary mechanical protection.
    Q What is the minimum shave diameter and why does it matter?
    The minimum shave (sheave) diameter is 670 mm (26.4"). This specification defines the smallest pulley or wheel diameter that the cable can safely pass over without causing damage to the armor wires or internal conductors. Using a sheave smaller than this diameter may result in permanent deformation or premature cable failure.
