❓ Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable is rated for a continuous maximum temperature of 246 °C (480 °F). For short-term exposure, it can withstand up to 280 °C (540 °F) for 1 hour, or 260 °C (500 °F) for up to 8 hours.
Q
What is the cable's voltage rating and insulation resistance?
This cable carries a voltage rating of 1500 VDC and an insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), making it suitable for demanding downhole electrical applications.
Q
What is the maximum working tension recommended for this cable?
The maximum suggested working tension is 27.5 kN (6,150 lbs), which is 50% of the cable's total breaking strength of 55 kN (12,300 lbs). Staying within this limit ensures safe and reliable long-term operation.
Q
What type of insulation material is used in this cable?
The cable uses PEA (Polyether Amine) insulation with a diameter of 3.81 mm (0.1496"). PEA offers excellent thermal stability and chemical resistance, making it ideal for high-temperature downhole environments.
Q
What is the minimum sheave (pulley) diameter for this cable?
The minimum sheave diameter is 450 mm (18 inches). Using a sheave smaller than this specification may cause excessive bending stress, potentially compromising the cable's structural and electrical integrity.
Q
How is the armor constructed and what is the wire breaking strength?
The cable features a double-armor construction: an inner armor of 12 × 1.11 mm wires and an outer armor of 18 × 1.11 mm wires. Both the inner and outer armor wires have an average breaking strength of 1970 N (442 lbs) per wire, providing robust mechanical protection in demanding well environments.
