CEFRP marine cable is a type of cable designed specifically for ships and marine environments, with characteristics such as corrosion resistance, oil resistance, water resistance, and flame retardancy, suitable for complex offshore working conditions.

Application scenarios

Ship power system: main distribution board, generator, electric motor and other power supply lines.

Control circuit: Low voltage control circuits for instruments, signal transmission, etc.

Marine engineering: offshore platforms, floating production storage and offloading vessels (FPSOs), etc.

Damp environment: areas such as cabins, decks, pump rooms, etc.

When selecting CEFRP marine cables, it is necessary to comprehensively consider factors such as ship environment, electrical performance, safety standards, and laying conditions.

1. Clearly define the usage environment and purpose

Application Scenario:

Inside the engine compartment: It needs to be resistant to oil and high temperatures (such as near the engine).

Deck/outdoor area: UV resistant, waterproof, and salt spray resistant.

Cabin/residential area: Low smoke and halogen-free (LSZH) is required to meet fire safety requirements.

Mobile or fixed installation:

Frequent movement (such as drag chains) requires the use of highly flexible cables; Fixed installation can choose conventional models.

2. Electrical parameter matching

Voltage level: Commonly available are 0.6/1kV, 3.6/6kV, etc., which need to be matched with the system voltage.

Conductor cross-sectional area: selected according to the load current (such as 16mm ², 25mm ², etc.), referring to IEC 60364 standard.

Current carrying capacity: Consider environmental temperature (such as reducing capacity for use above 40 ° C).

3. Material and structural requirements

Conductor: Multiple strands of thin copper wire (Class 5 or 6) to ensure flexibility.

Insulation layer:

Ethylene propylene rubber (EPR): resistant to high temperatures (up to 90 ° C) and aging.

Cross linked polyethylene (XLPE): Higher temperature resistance (105 ° C), good mechanical strength.

Sheath:

Neoprene: Oil resistant, wear-resistant, suitable for engine compartments.

Polyvinyl chloride (PVC): Low cost, but poor oil resistance.

Shielding layer (optional): Copper wire braided shielding to resist electromagnetic interference (such as instrument signal lines).

4. Safety certification and standards

Classification society certification: Must be certified by at least one mainstream classification society, such as:

DNV-GL, ABS (USA), BV (France), CCS (China), etc.

Flame retardant and fire-resistant:

IEC 60332 (flame retardant test), IEC 61034 (low smoke test).

Low smoke halogen-free (LSZH) cables are preferred for residential areas.

5. Mechanical and environmental tolerance

Oil resistance: Complies with IEC 60811-404 standard (such as cables used in engine rooms).

Waterproof: The sheath has good sealing performance (such as IP68 rating for underwater areas).

Tensile strength: When used for vertical laying, it is necessary to strengthen the armor (such as steel wire weaving).

6. Laying and installation conditions

Bending radius: The minimum bending radius for flexible cables is usually 6 times the outer diameter of the cable.

Laying method:

Cable tray laying: UV resistance is required.

Pipe laying: The outer sheath should be smooth (such as PVC).

Environmental temperature: High temperature resistant models (such as -40 ° C~+90 ° C) should be selected for tropical waters.
