Q1
What is the voltage rating of this cable, and is it suitable for downhole ESP applications?
This cable carries a voltage rating of 300 VDC. It is engineered for demanding downhole environments, including Electric Submersible Pump (ESP) systems, where reliable, low-voltage DC signal or power transmission is required under high mechanical stress.
Q2
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 121 °C (250 °F). For short-duration exposure, it can withstand up to 135 °C (275 °F) for 8 hours and up to 150 °C (300 °F) for 1 hour, making it suitable for elevated-temperature downhole formations.
Q3
What is the cable breaking strength, and what working tension is recommended?
The cable has a breaking strength of 25 kN (5,400 lbs). The maximum suggested working tension is 12.5 kN (2,800 lbs) — exactly 50% of the breaking strength — to ensure a safe operational safety factor during deployment and retrieval operations.
Q4
What is the dual-armor construction of this cable and why does it matter?
The cable features a dual-armor design: an inner armor of 18×0.63 mm wires (average breaking strength 582 N / 131 lbs) and an outer armor of 18×0.89 mm wires (breaking strength 1,162 N / 261 lbs). This layered construction provides superior crush resistance, tensile integrity, and protection against downhole abrasion.
Q5
What is the insulation resistance rating, and why is it critical for signal cables?
The insulation resistance is rated at 15,000 MΩ·km (50,000 MΩ·kft). A high insulation resistance minimizes leakage current and signal loss over long cable runs, ensuring measurement accuracy and data integrity in deep well logging and monitoring applications.
Q6
What is the minimum sheave diameter required for this cable?
The minimum sheave (pulley) diameter for this cable is 356 mm (14 inches). Using sheaves smaller than this specification may cause permanent deformation of the armor wires or conductor, which can degrade both mechanical strength and electrical performance over time.
