Frequently Asked Questions
Q
What type of insulation materials are used in this cable, and why?
A
This cable uses both FEP (Fluorinated Ethylene Propylene) and ETFE (Ethylene Tetrafluoroethylene) insulation materials. FEP offers excellent chemical resistance and a low dielectric constant, while ETFE provides superior mechanical toughness and higher temperature performance. Together, they make the cable suitable for demanding downhole environments.
Q
What is the maximum continuous operating temperature of this cable?
A
The cable is rated for a continuous maximum temperature of 204 ℃ (400 °F). For short durations, it can withstand up to 260 ℃ (500 °F) for 1 hour, or 232 ℃ (450 °F) for up to 8 hours, providing operational flexibility in high-temperature well environments.
Q
What is the cable's maximum working tension and breaking strength?
A
The cable has a total breaking strength of 45.4 kN (10,200 lbs). The maximum suggested working tension is 22.7 kN (5,100 lbs), which is approximately 50% of the breaking strength — a standard safety margin for reliable long-term deployment in wireline and logging operations.
Q
What voltage and insulation resistance ratings does this cable support?
A
The cable supports a voltage rating of 1200 VDC, making it suitable for powering downhole tools and transmitting measurement signals. It also features an exceptionally high insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), ensuring reliable signal integrity and minimal leakage current in wet or high-pressure conditions.
Q
What is the minimum shave (sheave) diameter required for this cable?
A
The minimum sheave diameter for this cable is 410 mm (16 inches). Using sheaves smaller than this recommendation can cause permanent deformation of the armor wires, reduce breaking strength, or damage the internal conductor and insulation, shortening the cable's service life.
Q
How is the dual-armor construction of this cable beneficial for oilfield use?
A
The dual-armor design — featuring 12-wire inner armor and 18-wire outer armor, each with an average breaking strength of 1750 N (393 lbs) per wire — provides torque balance, crush resistance, and high tensile load capacity. This construction minimizes cable rotation and birdcaging during deployment, making it highly reliable for deep well wireline logging, perforation, and well intervention operations.
