💬 Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable is rated for a continuous maximum temperature of 204 ℃ (400 °F). For short-term operation, it can withstand up to 260 ℃ (500 °F) for 1 hour, or 232 ℃ (450 °F) for up to 8 hours.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a breaking strength of 40 kN (9,000 lbs). The maximum suggested working tension is 20 kN (4,500 lbs), which is 50% of the breaking strength to ensure a safe operating margin.
Q
What type of insulation is used and what are the differences between FEP and ETFE options?
The cable is available with either FEP insulation (2.85 mm / 0.1122") or ETFE insulation (3.81 mm / 0.1496"). Both materials offer excellent high-temperature resistance and chemical stability; ETFE provides a slightly larger insulation diameter and generally offers superior abrasion resistance.
Q
What is the voltage rating and insulation resistance of this cable?
This cable is rated at 1,500 VDC. The insulation resistance is an exceptionally high 15,000 MΩ·km (50,000 MΩ·kft), making it well-suited for high-precision measurement and downhole logging applications.
Q
What is the armor construction of this cable?
The cable features a double-armor construction. The inner armor consists of 12 wires at 1.11 mm (0.0437") diameter, and the outer armor consists of 18 wires at 1.11 mm (0.0437") diameter. Each individual armor wire has an average breaking strength of 1,600 N (360 lbs).
Q
What is the minimum sheave diameter required for this cable?
The minimum sheave (pulley) diameter for this cable is 4,500 mm (18 inches). Using a sheave smaller than this minimum may cause permanent damage to the cable structure, reduce its service life, or compromise its mechanical and electrical performance.
