    Frequently Asked Questions
    Q What is the maximum continuous operating temperature of this cable?
    The cable is rated for a continuous maximum temperature of 121 ℃ (250 °F). For short-term operation, it can withstand up to 135 ℃ (275 °F) for 8 hours, and up to 150 ℃ (300 °F) for 1 hour.
    Q What is the cable 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 approximately 50% of the breaking strength — ensuring a safe safety factor during field operations.
    Q What voltage rating does this cable support?
    This cable carries a voltage rating of 1200 VDC, making it suitable for high-voltage direct current downhole applications commonly used in oil and gas well logging operations.
    Q What is the insulation material and its resistance specification?
    The insulation is made of Polypropylene (PP) with a diameter of 2.13 mm (0.0838"). The insulation resistance is rated at 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation under downhole conditions.
    Q What is the minimum sheave diameter required for this cable?
    The minimum sheave (pulley) diameter for this cable is 670 mm (26.4"). Using a sheave smaller than this specification can cause mechanical damage to the cable armor and reduce its service life.
    Q What are the armor construction details and their breaking strengths?
    The cable features a double-armor construction. The inner armor consists of 18 wires × 1.19 mm (0.0468") with an average wire breaking strength of 2,170 N (488 lbs). The outer armor consists of 18 wires × 1.66 mm (0.0653") with an average wire breaking strength of 4,220 N (948 lbs), providing robust mechanical protection for demanding downhole environments.
