Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable is rated for a continuous maximum temperature of 204 ℃ (400 °F). For short-term exposure, it can withstand up to 260 ℃ (500 °F) for 1 hour, and 232 ℃ (450 °F) for up to 8 hours.
Q
What is the cable's breaking strength and recommended working tension?
The cable has an ultimate breaking strength of 140 kN (31,500 lbs). The maximum suggested working tension is 70 kN (15,750 lbs), which represents a 2:1 safety factor over the breaking load.
Q
What insulation materials are used, and why are FEP and ETFE chosen?
The insulation is constructed from FEP (Fluorinated Ethylene Propylene) and ETFE (Ethylene Tetrafluoroethylene). Both materials are selected for their excellent high-temperature resistance, chemical inertness, and superior electrical insulation properties, making them ideal for demanding downhole environments.
Q
What is the voltage rating and insulation resistance of this cable?
The cable carries a voltage rating of 1200 VDC. Its insulation resistance is rated at 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent signal integrity and minimal leakage current in high-temperature logging applications.
Q
What is the minimum sheave (pulley) diameter recommended for this cable?
The minimum sheave diameter is 576 mm (22.6 inches). Using a sheave smaller than this specification may cause excessive bending stress, potentially damaging the armor wires or the internal conductor and insulation layers.
Q
What are the armor wire specifications and their breaking strengths?
The inner armor consists of 22 wires at 1.11 mm diameter each, with an average breaking strength of 2,514 N (565 lbs) per wire. The outer armor consists of 22 wires at 1.44 mm diameter each, with an average breaking strength of 4,232 N (952 lbs) per wire, providing the cable's overall robust tensile load capacity.
