Frequently Asked Questions
What is the maximum continuous operating temperature of this cable?
The cable is rated for a continuous maximum temperature of 204 °C (400 °F). For short-duration exposure, it can withstand up to 260 °C (500 °F) for 1 hour and 232 °C (450 °F) for 8 hours, making it suitable for high-temperature downhole environments.
What is the cable breaking strength and recommended working tension?
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 — ensuring a reliable safety margin during deployment and operation.
What type of insulation material is used in this cable?
This cable uses FEP (Fluorinated Ethylene Propylene) and ETFE (Ethylene Tetrafluoroethylene) insulation materials. These fluoropolymer materials offer excellent chemical resistance, high-temperature performance, and superior electrical insulation properties ideal for downhole applications.
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 1200 VDC. Its insulation resistance is exceptionally high at 15,000 MΩ·km (50,000 MΩ·kft), providing excellent electrical isolation to prevent leakage and ensure reliable signal or power transmission in demanding well environments.
What is the minimum shave diameter required for this cable?
The minimum shave (sheave) diameter for this cable is 576 mm (22.6"). Using a sheave smaller than this specification may cause mechanical stress, deformation of the armor wires, or permanent damage to the cable structure, reducing its service life and reliability.
How is the copper conductor constructed in this cable?
The conductor consists of 7 individual copper strands, each 0.36 mm (0.0142") in diameter. This stranded construction provides improved flexibility compared to a solid conductor, while maintaining low electrical resistance of 26.5 Ω/km (8 Ω/kft) at 20 °C, ensuring efficient signal transmission.
