Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 121 ℃ (250 °F). For short-term operation, it can handle up to 135 ℃ (275 °F) for 8 hours and up to 150 ℃ (300 °F) for 1 hour.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a breaking strength of 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 safe and reliable operation.
Q
What voltage rating does this cable support?
This cable is rated at 1000 VDC, making it suitable for downhole electrical submersible pump (ESP) and other high-voltage direct current applications in oil and gas environments.
Q
What type of armor construction does the cable use?
The cable features a dual-armor construction. The inner armor consists of 24 wires at 0.99 mm (0.0389") diameter with a breaking strength of 1,438 N (323 lbs) per wire, while the outer armor uses 24 wires at 1.26 mm (0.0496") diameter with a breaking strength of 2,330 N (523 lbs) per wire.
Q
What is the insulation material and its resistance rating?
The cable uses Polypropylene (PP) insulation with a diameter of 2.48 mm (0.0976"). The insulation resistance is rated at 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation in demanding downhole conditions.
Q
What is the minimum shave (sheave) diameter required for this cable?
The minimum sheave diameter for this cable is 504 mm (20 inches). Using a sheave smaller than this specification may cause mechanical damage to the armor wires or internal conductors and should be strictly avoided during installation and operation.
