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 operations, it can withstand up to 135 ℃ (275 °F) for 8 hours and 150 ℃ (300 °F) for 1 hour.
Q
What is the cable breaking strength and recommended working tension?
The cable breaking strength is 8 kN (1800 lbs). The maximum suggested working tension is 4 kN (900 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 300 VDC, making it suitable for downhole and wireline logging applications that require stable low-voltage DC power transmission.
Q
What are the inner and outer armor construction specifications?
The inner armor consists of 12 wires × 0.47 mm (0.0185") and the outer armor consists of 18 wires × 0.47 mm (0.0185"). Both inner and outer armor have an average wire breaking strength of 324 N (72.8 lbs).
Q
What is the insulation resistance of the cable?
The cable offers an exceptionally high insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation and reliable signal transmission in harsh downhole environments.
Q
What is the minimum sheave diameter recommended for this cable?
The minimum sheave (pulley) diameter recommended for this cable is 190 mm (7.5"). Using a sheave smaller than this may cause excessive bending stress and could damage the armor or conductor over time.
