💬 Frequently Asked Questions
❓
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 204 ℃ (400 °F). For short-term exposure, it can withstand up to 260 ℃ (500 °F) for 1 hour, and 232 ℃ (450 °F) for up to 8 hours.
❓
What is the cable's breaking strength and recommended working tension?
The cable has a total breaking strength of 45 kN (10,125 lbs). The maximum suggested working tension is 22.5 kN (5,062.5 lbs), which is 50% of the breaking strength to ensure a safe operating margin.
❓
What insulation materials are used, and what are their diameters?
The cable uses two insulation material options: FEP (Fluorinated Ethylene Propylene) with a diameter of 2.85 mm (0.1122"), and ETFE (Ethylene Tetrafluoroethylene) with a diameter of 3.81 mm (0.1496"). Both materials offer excellent high-temperature and chemical resistance.
❓
What is the voltage rating and insulation resistance of the cable?
The cable is rated at 1500 VDC. Its insulation resistance is exceptionally high at 15,000 MΩ·km (50,000 MΩ·kft), making it suitable for demanding downhole electrical applications where leakage must be minimized.
❓
What is the minimum shave (sheave) diameter for this cable?
The minimum sheave diameter for this cable is 450 mm (18 inches). Using a sheave smaller than this minimum can cause mechanical damage to the armor wires and reduce the cable's service life.
❓
How is the armor construction designed, and what is each wire's breaking strength?
The cable features a double-armor construction: an inner armor of 12 wires (each 1.11 mm / 0.0437") and an outer armor of 18 wires (each 1.11 mm / 0.0437"). Each individual armor wire has an average breaking strength of 1,644 N (370 lbs), providing robust mechanical protection for downhole deployment.
