❓ Frequently Asked Questions
Q
What type of insulation material is used in this cable?
A
This cable uses FEP (Fluorinated Ethylene Propylene) and ETFE (Ethylene Tetrafluoroethylene) insulation, both of which are high-performance fluoropolymer materials known for excellent heat resistance, chemical resistance, and electrical insulation properties.
Q
What is the maximum continuous operating temperature of this cable?
A
The cable supports a continuous maximum temperature of 204 ℃ (400 °F). For short-term operations, it can handle up to 232 ℃ (450 °F) for 8 hours and 260 ℃ (500 °F) for 1 hour.
Q
What is the maximum voltage rating for this cable?
A
The cable has a voltage rating of 1200 VDC, making it suitable for high-voltage direct current downhole applications typically found in oil and gas well logging operations.
Q
What is the cable breaking strength and recommended working tension?
A
The cable has a breaking strength of 140 kN (31,500 lbs). The maximum suggested working tension is 70 kN (15,750 lbs), which is 50% of the breaking strength — a standard safety factor for reliable and safe field operations.
Q
What is the difference between the inner armor and outer armor?
A
The inner armor consists of 22 wires at 1.11 mm diameter with a breaking strength of 2514 N (565 lbs), while the outer armor uses 22 wires at 1.44 mm diameter with a higher breaking strength of 4232 N (952 lbs). The dual-armor construction provides enhanced mechanical protection and tensile strength for demanding downhole environments.
Q
What is the insulation resistance of this cable and why does it matter?
A
The insulation resistance is rated at 15,000 MΩ·km (50,000 MΩ·kft). A high insulation resistance value is critical in logging cables as it ensures minimal electrical leakage, maintains signal integrity, and guarantees reliable data transmission even under extreme downhole temperature and pressure conditions.
