💬 Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 200 ℃ (392 °F). For short-duration high-heat scenarios, it can handle up to 232 ℃ (450 °F) for 1 hour or 216 ℃ (421 °F) for up to 8 hours.
Q
What is the cable breaking strength and recommended working tension?
The cable has a total breaking strength of 100 kN (22,500 lbs). The maximum suggested working tension is 50 kN (11,250 lbs), which is 50% of the breaking strength to ensure a safe operational margin.
Q
What type of insulation material is used in this cable?
This cable uses FEP (Fluorinated Ethylene Propylene) insulation with a diameter of 2.48 mm (0.0976"). FEP is chosen for its excellent thermal stability, chemical resistance, and suitability for high-temperature downhole environments.
Q
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 1200 VDC. Its insulation resistance is 15,000 MΩ·km (50,000 MΩ·kft), ensuring excellent electrical isolation for reliable signal transmission in demanding downhole conditions.
Q
What is the minimum shave diameter and why does it matter?
The minimum shave (sheave) diameter is 504 mm (20"). This specification defines the smallest diameter pulley or wheel over which the cable can be safely bent during deployment or retrieval operations, helping to prevent mechanical fatigue and structural damage to the armor wires.
Q
How is the dual-armor construction beneficial for downhole applications?
The dual-armor construction — featuring an inner armor (24×1.00 mm) and an outer armor (24×1.26 mm) — provides layered mechanical protection against crush forces, tension loads, and abrasion encountered in harsh downhole environments. The combined armor structure contributes to the cable's overall 100 kN breaking strength, making it highly reliable for deep logging and wireline operations.
