NSGAFÖU 1Cx120mm2 6/10kV

Typowe problemy

• Insulation resistance degradation from moisture ingress at terminations or a damaged outer sheath
• Mechanical damage to the outer sheath from chafing against structure or poor cable route support
• Overheating/insulation aging at terminations from loose connections or undersized termination kits
• Developing partial discharge activity in aged or damaged insulation at this voltage class
• Sheath cracking from repeated flexing at cable transits or, on exposed runs, UV exposure
• Water treeing in the insulation over long service life, particularly in damp environments

Lista kontrolna przeglądu

• Visual inspection of accessible cable runs for sheath damage, chafing, or degraded supports
• Insulation resistance (megger) test at scheduled intervals and after any suspected damage
• Thermal (infrared) scan of terminations and switchgear connections under load
• Inspect cable transits/glands for sealing integrity (watertight/gastight as required)
• Check termination and joint condition for signs of overheating or tracking
• Verify cable support and clamping is intact with no excessive sagging or chafe points
• Confirm fire-stopping at bulkhead/deck penetrations is intact

Krytyczne części zamienne

• Termination/jointing kit rated for 6/10kV, matching cable size and insulation type
• Cable glands matching the cross-section and armor type
• Spare cable length for emergency repair (maker/yard-specified minimum run)
• Heat-shrink or cold-shrink termination repair accessories

Bezpieczeństwo

• 6/10kV is high voltage for marine systems - strict lock-out/tag-out and voltage-absence verification is required before any work
• Residual charge in HV cables after de-energization - discharge and earth before handling
• Damaged insulation on an energized HV cable presents a flashover/arc-flash risk
• Fire risk from overheated terminations - never exceed the cable's current rating or ignore a recurring thermal hot spot

Przegląd klasyfikacyjny

Class surveys of high-voltage cable systems typically require insulation resistance test records, confirmation of cable route fire integrity at transits/penetrations, and periodic HV testing per the applicable class rules for 6/10kV distribution.

Szacowana trwałość: Not applicable in running hours - marine 6/10kV power cable of this type is typically designed for a service life of 20-25+ years, condition permitting, and is assessed by insulation testing rather than hour-based renewal
