💬 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-duration applications, it can handle 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 13 kN (2,900 lbs). The maximum suggested working tension is 6.5 kN (1,450 lbs), which is 50% of the breaking strength — ensuring a safe operational margin during deployment.
Q
What type of conductor is used and how is it constructed?
The conductor uses a 7-strand copper construction, with each strand measuring 0.21 mm (0.0082") in diameter. This stranded design provides flexibility and durability for wireline logging applications.
Q
What is the voltage rating and insulation resistance of this cable?
The cable carries a voltage rating of 200 VDC. The insulation resistance is rated at 15,000 MΩ·km (50,000 MΩ·kft), providing excellent electrical isolation suitable for precision downhole measurement environments.
Q
What is the minimum sheave (shave) diameter recommended for this cable?
The minimum sheave diameter is 260 mm (10.5"). Using a sheave smaller than this recommendation can cause excessive bending stress on the armor wires, leading to premature fatigue and reduced cable service life.
Q
How does the dual-armor construction benefit cable performance?
The dual-armor design features an inner armor of 18 × 0.47 mm wires (breaking strength: 324 N / 72.8 lbs) and an outer armor of 18 × 0.64 mm wires (breaking strength: 601 N / 135 lbs). This layered armoring provides superior crush resistance, tensile strength, and protection against harsh downhole environments.
