Frequently Asked Questions
Q1
What type of insulation is used in this cable, and why?
This cable uses FEP (Fluorinated Ethylene Propylene) insulation with a diameter of 2.48 mm. FEP is chosen for its exceptional thermal resistance, supporting continuous operating temperatures up to 204 ℃ (400 °F), making it ideal for high-temperature downhole environments.
Q2
What is the maximum working tension this cable can safely handle?
The cable has a breaking strength of 117 kN (26,300 lbs). The maximum suggested working tension is 58.5 kN (13,150 lbs), which represents a 50% safety factor to ensure reliable and safe operation during deployment.
Q3
What is the dual-armor construction and what does it provide?
The cable features a dual-armor design: an inner armor of 24×1.00 mm wires (breaking strength 2,041 N / 459 lbs per wire) and an outer armor of 24×1.26 mm wires (3,240 N / 729 lbs per wire). This layered armor provides superior mechanical protection, crush resistance, and tensile strength for demanding well conditions.
Q4
What are the temperature ratings for this cable?
The cable supports three temperature ratings: a continuous maximum of 204 ℃ (400 °F), an 8-hour maximum of 232 ℃ (450 °F), and a 1-hour maximum of 260 ℃ (500 °F). These ratings allow flexibility for short-term high-temperature events while maintaining safety.
Q5
What are the key electrical specifications of this cable?
The cable is rated at 1,000 VDC with a typical conductor resistance of 33 Ω/km (10 Ω/kft) at 20 ℃. The insulation resistance is exceptionally high at 15,000 MΩ·km, and the capacitance at 1 kHz is 130 pF/m, ensuring reliable signal transmission in logging and monitoring applications.
Q6
What is the minimum shave (sheave) diameter required for this cable?
The minimum recommended sheave diameter is 600 mm (23.6"). Using a sheave smaller than this minimum can cause excessive bending stress on the armor wires and internal conductors, potentially reducing the service life or causing mechanical failure of the cable.
