Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 246 ℃ (480 °F). For short-term applications, it can withstand up to 260 ℃ (500 °F) for 8 hours and up to 280 ℃ (540 °F) for 1 hour.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a 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 safe and reliable operation 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), making it suitable for high-voltage downhole logging and measurement applications.
Q
What type of insulation material is used in the cable construction?
The cable uses PEA (Polyether Amide) insulation with a diameter of 3.81 mm (0.1496"). PEA insulation is chosen for its excellent high-temperature resistance, chemical stability, and mechanical durability in downhole environments.
Q
What is the minimum sheave (pulley) diameter recommended for this cable?
The minimum sheave diameter is 450 mm (18"). Using a sheave smaller than this recommendation may cause excessive bending stress, potentially leading to premature wear or structural damage to the armor wires.
Q
How is the armor construction designed, and what are the wire breaking strengths?
The cable features a double-armor construction. The inner armor consists of 12 wires at 1.11 mm diameter, and the outer armor consists of 18 wires at 1.11 mm diameter. Both inner and outer armor wires have an average breaking strength of 1970 N (442 lbs) per wire, providing robust mechanical protection.
