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 exposure, it can withstand up to 135 ℃ (275 °F) for 8 hours and 150 ℃ (300 °F) for 1 hour.
Q
What is the cable's breaking strength and recommended working tension?
The cable breaking strength is 85 kN (19,100 lbs). The maximum suggested working tension is 42.5 kN (9,550 lbs), which is 50% of the breaking strength to ensure a safe operating margin.
Q
What voltage rating does this cable support?
This cable has a voltage rating of 1000 VDC, making it suitable for a wide range of downhole and industrial DC power applications.
Q
What are the armor specifications of this cable?
The cable features a dual-armor construction. The inner armor consists of 24 wires at 0.99 mm (0.0389") each with an average breaking strength of 1,438 N (323 lbs). The outer armor consists of 24 wires at 1.26 mm (0.0496") each with an average breaking strength of 2,330 N (523 lbs).
Q
What is the insulation resistance of this cable?
The insulation resistance is rated at 15,000 MΩ·km (50,000 MΩ·kft), indicating excellent electrical isolation performance suitable for high-reliability downhole environments.
Q
What is the minimum shave (sheave) diameter for this cable?
The minimum shave diameter is 504 mm (20 inches). Using a sheave smaller than this minimum can cause damage to the armor wires and reduce the cable's overall service life.
