CEFR-0.6/1kV
CEF / CEFR Shipboard Power Cable to IEC 60092-353
Tinned copper, EPR or XLPE insulation and a compound selected for salt, oil and vibration.
Shipboard power cable works where a fault means losing propulsion or lighting at sea: a salt-laden, vibrating, humid environment with fuel and hydraulic oil in the same space. IEC 60092-350 sets the general construction and test methods, IEC 60092-353 covers power cables at 1 kV and 3 kV, and IEC 60092-360 defines the insulation compounds. CEF and CEFR are the Chinese designations for EPR-insulated shipboard power cable, with CEFR the flexible version used where a run has to move or where termination space is tight.
Two details separate marine cable from land cable. The conductor is tinned so salt-laden humidity does not corrode the fine strands inside a crimp, and the sheath is chosen for oil, ozone and low-temperature flexibility rather than for flame retardance alone. Voltcore supplies the halogen-free SHF1 or SHF2 compound where the specification calls for low smoke, and a polychloroprene option where oil resistance and mechanical toughness come first, both to IEC 60092-359 requirements.

Engineering characteristics
- Tinned copper conductor to IEC 60228 resists corrosion from salt-laden humidity under a crimp, the usual cause of high-resistance terminations on board.
- EPR insulation at 85 °C with an XLPE option at 90 °C, both to the compound requirements of IEC 60092-360.
- Halogen-free SHF2 sheath gives not more than 5 mg/g acid gas to IEC 60754-1 and 60% or better light transmittance to IEC 61034-2.
- Bunched flame retardance to IEC 60332-3-22 category A, the category normally cited in shipbuilding specifications.
- Operating range -40 °C to +85 °C, so cold deck and refrigerated space runs need no special low-temperature grade.
- Class 5 flexible construction bends to 6 × OD, which matters in engine rooms routing around machinery.
- Sheath compound selected for oil and ozone resistance to IEC 60092-359 and tested against fluids found in machinery spaces.
Typical applications
- Ship main and emergency power distribution
- Engine room machinery supplies and pump motors

CEF / CEFR Shipboard Power Cable — frequently asked questions
Is this cable type-approved by ABS, DNV, LR, BV or CCS?
No, and Voltcore does not claim it. The cable is designed and tested to IEC 60092-350, -353, -359 and -360 and can be supplied to the requirements of those societies' rules. Where a yard or operator requires documented verification, third-party witnessed type and routine testing is arranged and quoted as a separate line before manufacture.
Why is the conductor tinned rather than plain copper?
Salt-laden humidity migrates into a crimp and corrodes plain copper strands, raising termination resistance until the joint runs hot. Tin plating slows that corrosion and keeps the crimp stable for the life of the installation. It adds cost and a little resistance, which is why it is standard for marine cable and optional for land cable.
What is the difference between SHF1 and SHF2 sheathing?
Both are halogen-free. SHF1 is thermoplastic and suits moderate temperature duty. SHF2 is thermosetting, or cross-linked, and holds its mechanical and electrical properties at higher temperature and after exposure to oil-based fluid. NEK 606 requires SHF2 for mud resistance, which is why offshore specifications name it rather than asking for halogen-free cable generally.
Can CEFR be supplied at 3 kV or medium voltage?
Yes. A 0.6/3 kV version is built to IEC 60092-353 and medium-voltage constructions from 3.6/6 kV to 18/30 kV follow IEC 60092-354, with conductor and insulation screens and a metallic screen or braid. Send the voltage, core count and route length, and Voltcore returns dimensions and the applicable test schedule.
