Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum operating temperature of 246 °C (480 °F). For short-term exposure, it can withstand up to 260 °C (500 °F) for 8 hours or 280 °C (540 °F) for 1 hour, making it suitable for high-temperature downhole environments.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a total breaking strength of 55 kN (12,300 lbs). The maximum suggested working tension is 27.5 kN (6,150 lbs), which is 50% of the breaking strength — a standard safety factor for reliable long-term deployment.
Q
What type of insulation material is used in this cable?
This cable uses PEA (Polyether Amide) insulation with a diameter of 3.81 mm (0.1496"). PEA insulation offers excellent thermal stability, chemical resistance, and electrical performance, making it ideal for demanding oil and gas well logging applications.
Q
What is the voltage rating and insulation resistance of this cable?
The cable is rated at 1500 VDC. Its insulation resistance is exceptionally high at 15,000 MΩ·km (50,000 MΩ·kft), ensuring minimal signal leakage and reliable electrical transmission even in harsh downhole conditions.
Q
What is the armor construction of this cable?
The cable features a double-armor construction: an inner armor of 12 wires (1.11 mm diameter) and an outer armor of 18 wires (1.11 mm diameter). Each armor wire has an average breaking strength of 1,970 N (442 lbs), providing robust mechanical protection against tension, crush, and abrasion during deployment.
Q
What is the minimum sheave diameter recommended for this cable?
The minimum recommended sheave (pulley) diameter for this cable is 450 mm (18 inches). Using sheaves smaller than this specification may cause excessive bending stress, accelerating wear and potentially reducing the cable's service life and mechanical integrity.
