Frequently Asked Questions
Q
What is the maximum continuous operating temperature of this cable?
The cable supports a continuous maximum temperature of 121 ℃ (250 °F). For short-duration high-heat scenarios, it can withstand up to 135 ℃ (275 °F) for 8 hours or 150 ℃ (300 °F) for 1 hour.
Q
What is the cable's breaking strength and recommended working tension?
The cable has a breaking strength of 4 kN (900 lbs). The maximum suggested working tension is 2 kN (450 lbs), which is 50% of the breaking strength to ensure a reliable safety margin during operation.
Q
What voltage rating does this cable support?
This cable is rated at 300 VDC. It also offers an insulation resistance of 15,000 MΩ·km (50,000 MΩ·kft), making it well-suited for low-voltage downhole instrumentation and data transmission applications.
Q
What is the minimum shave diameter for this cable?
The minimum shave (sheave) diameter for this cable is 150 mm (6.0"). Using a sheave smaller than this minimum may result in damage to the armor wires or conductor and can reduce the cable's service life.
Q
What are the armor wire specifications for inner and outer layers?
The inner armor consists of 12 wires at 0.36 mm (0.0141") diameter each, while the outer armor consists of 18 wires at the same 0.36 mm (0.0141") diameter. Both armor layers have an average wire breaking strength of 190 N (421 lbs).
Q
What is the cable's electrical resistance and capacitance?
At 20 ℃, the typical conductor resistance is 75 Ω/km (22.8 Ω/kft). The capacitance measured at 1 kHz is 167 pF/m (51 pF/ft), which is an important parameter for signal integrity in wireline logging and telemetry systems.
