❓ Frequently Asked Questions
Q: What is the maximum continuous operating temperature of this cable?
A: The cable supports a continuous maximum operating temperature of 121 ℃ (250 °F). For short-term use, 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?
A: 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 approximately 50% of the breaking strength to ensure safe operation.
Q: What voltage rating does this cable support?
A: This cable is rated for 1200 VDC. It also features a high insulation resistance of 15,000 MΩ·km (metric) or 50,000 MΩ·kft (imperial), making it suitable for demanding downhole electrical applications.
Q: What type of insulation material is used in this cable?
A: The cable uses Polypropylene (PP) insulation with a diameter of 2.13 mm (0.0838"). PP insulation offers excellent resistance to heat, chemicals, and mechanical stress in harsh environments.
Q: What is the minimum shave diameter for this cable?
A: The minimum shave (sheave) diameter for this cable is 670 mm (26.4"). Using a sheave smaller than this minimum specification may result in cable damage or reduced service life.
Q: What are the armor wire breaking strengths for the inner and outer armor?
A: The inner armor has an average wire breaking strength of 2,170 N (488 lbs), while the outer armor is significantly stronger at 4,220 N (948 lbs). This dual-armor design provides robust mechanical protection for the cable.
