LSM-HF 1,8/3 kV or TEMAR PHFX-A 1,8/3 kV

Common issues

• Insulation thermal ageing at heavily loaded cable runs, especially near switchboards
• Gland moisture ingress at deck and bulkhead penetrations
• Mechanical damage sustained during cable pulling or later maintenance work nearby
• Screen or armour corrosion in damp trunking or bilge-adjacent routes
• Overheating at poorly torqued terminations rather than the cable itself
• Rodent or mechanical chafe damage inside cable trunking on older vessels

Inspection checklist

• Thermal check (by hand-held thermometer or thermal imaging where available) at terminations and lugs
• Insulation resistance test on the run, logged and trended over time
• Check termination and lug tightness/torque at switchboards and junction boxes
• Visual inspection of the cable route for chafe, crushing, or exposed conductor
• Check cable support spacing has not sagged or allowed chafe against structure
• Confirm cable identification/tagging is legible and matches the single-line/cable schedule
• Check earthing continuity of screen/armour where fitted

Service intervals

Critical spares

• Spare cable length of the correct rating and fire/halogen performance
• Cable lugs and terminations matching conductor size
• Heat-shrink termination and jointing kits
• Cable glands rated for the installation location

Safety

• Shock and arc-flash hazard at terminations carrying up to 1.8/3 kV - isolate and prove dead before working
• Fire risk from insulation failure if the wrong cable type or a damaged run has gone unnoticed
• Confined cable routes through trunking where access for inspection is limited

Class survey

Class checks that the DNV type-approved cable actually installed matches the approved cable schedule for this circuit, that halogen-free/low-smoke requirements for the space are met, and wants insulation resistance test records available at survey rather than a one-off check on the day.
