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 exposure, it can withstand up to 135 ℃ (275 °F) for 8 hours, and up to 150 ℃ (300 °F) for 1 hour, making it suitable for demanding downhole environments.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a total breaking strength of 55 kN (12,300 lbs). The maximum suggested working tension is 27.5 kN (6,150 lbs), which is 50% of the breaking strength, ensuring a safe operational safety factor during deployment.
Q
What voltage rating does this cable support?
This cable is rated at 1500 VDC, with an insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation and reliable signal or power transmission in high-voltage downhole applications.
Q
What are the armor construction details and their breaking strengths?
The cable features a dual-armor design: the inner armor consists of 12 wires × 1.11 mm, and the outer armor consists of 18 wires × 1.11 mm. Both inner and outer armor wires have an average breaking strength of 1970 N (442 lbs) per wire, providing robust mechanical protection.
Q
What is the minimum sheave (pulley) diameter recommended for this cable?
The minimum recommended sheave diameter is 450 mm (18 inches). Using sheaves smaller than this specification may cause excessive bending stress, potentially damaging the armor wires or the insulation and reducing the cable's service life.
Q
What is the conductor construction and its electrical resistance?
The copper conductor is constructed with 19 strands × 0.37 mm wires, providing a flexible yet robust conductor. The typical DC resistance at 20 ℃ is 9.2 Ω/km (2.8 Ω/kft), and the capacitance is 190 pF/m (58 pF/ft) at 1 kHz, ensuring efficient electrical performance.
