Typical power cables
Example cable types in marine applications:
• Prysmian TEMA PHFX-A (LSM-HF)
• Nexans MPRXCX flexship.
These example cables are very flexible: stranded wire copper conductors and XLPE insulation
allowing max. 90 °C conductor temperature.
Typical installation on cable tray, with overall de-rating factor of 0.7.
