Frequently Asked Questions
Q
What type of insulation material is used in this cable, and why is it suitable for high-temperature environments?
This cable uses FEP (Fluorinated Ethylene Propylene) insulation, which is specifically engineered for demanding downhole environments. FEP offers excellent thermal stability, allowing the cable to operate continuously at up to 200 ℃ (392 °F), with short-term ratings reaching 232 ℃ (450 °F) for up to 1 hour. Its chemical resistance and low dielectric loss also make it ideal for electrical integrity in oil and gas well applications.
Q
What is the maximum working tension recommended for this cable?
The maximum suggested working tension is 42.5 kN (9,550 lbs), which represents 50% of the cable's total breaking strength of 85 kN (19,100 lbs). Operating within this limit ensures safe deployment and long service life, reducing the risk of armor fatigue or conductor damage during installation and retrieval operations.
Q
What do the inner and outer armor layers consist of, and what is their purpose?
The cable features a dual-armor construction: the inner armor consists of 24 wires at 0.99 mm diameter (0.0389"), and the outer armor consists of 24 wires at 1.26 mm diameter (0.0496"). Together, they provide mechanical protection against tensile loads, crush forces, and abrasion. The outer armor's larger wire size gives it a significantly higher breaking strength of 2,330 N (523 lbs) per wire, compared to the inner armor's 1,438 N (323 lbs).
Q
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 1,000 VDC, making it suitable for standard ESP (Electric Submersible Pump) and downhole monitoring applications. Its insulation resistance is exceptionally high at 15,000 MΩ·km (50,000 MΩ·kft), which indicates excellent electrical isolation and minimizes leakage current, ensuring reliable signal or power transmission even in wet or high-pressure downhole conditions.
Q
What is the minimum shave (sheave) diameter required when deploying this cable?
The minimum sheave diameter for this cable is 504 mm (20 inches). Using a sheave smaller than this specification can cause permanent deformation of the armor wires, damage to the FEP insulation, or compromise the structural integrity of the conductor. Always ensure that all surface equipment, including winches and guide sheaves, meet or exceed this minimum diameter requirement.
Q
How is the cable stretch coefficient used in field operations?
The cable stretch coefficient of 0.8 m/km per 5 kN (0.714 ft/kft per klbs) allows field engineers to calculate the expected elastic elongation of the cable under tension. This is critical for accurate depth measurement and tool positioning in wellbore operations. For example, if 5 kN of tension is applied over a 1 km cable run, the cable will stretch approximately 0.8 meters, which must be accounted for in depth corrections and tool placement calculations.
