Marine Cable
Marine cable, is a kind of wire and cable used for power, lighting, control, and communication transmission of various ships in rivers and sea and offshore or marine buildings, including marine power cable, marine control cable, marine communication cable, and so on. Usually, the marine cable has limited laying space, so the armored structure adopts metal wire braiding, which is the biggest difference between the structure and the land-based ordinary power, control, and communication cables.
Due to the harsher environmental conditions, ZMS is required to produce cables that are safe, reliable, long life, small in size, lightweight, and have excellent temperature resistance, fire resistance, flame resistance, oil resistance, moisture resistance, seawater resistance, excellent electrical and mechanical properties and other requirements.
Types of Marine Cables
Marine cables can be divided into marine power cables (including rated voltage frequency AC 1kV and the following low-voltage power cables and rated voltage frequency AC 3 ~ 15kV medium voltage power cables), marine control cables, marine communication cables, marine signal cables, and marine RF cables according to the scope of use.
Marine power cable: used for power transmission of various ships in rivers and sea and offshore or marine buildings.
Marine control cable: used for the control signal transmission of various ships in rivers and sea and offshore or marine buildings.
Marine communication cable: used for signal transmission and control systems in various propagation communication, electronic computer, and information processing equipment.
Marine Power Cable
The marine power cable can be used for power, lighting, and general control devices for various ships in rivers and sea and offshore oil platforms, and other water buildings. Metallurgy, chemical industry, electric power, and other industrial and mining enterprises are also applicable.
Conductor: Tinned copper wire
Insulation: Ethylene propylene rubber(EPR)/PVC
Filling
Wrapping tape
Inner sheath: Neoprene/chlorosulfonated polyethylene/polyvinyl chloride

The Use Requirements and Laying Conditions of Marine Cables
The Use Of Marine Cables And Laying Conditions
1. For power, lighting, and control cables in the river and sea vessels and floating buildings on the water. The working voltage is 500V AC or 1000V DC and below.
2. Flexible structure cable for connecting mobile electrical equipment, the rest are fixed for laying.
3. Steel wire braided cables are used in places susceptible to external damage. Copper braided cables are used in places where interference is prevented.
4. All cables can be used in places that require no delay
Requirements For The Use Of Marine Cables
1. The cable should apply to all places and various climatic conditions and can withstand the cold, dry, hot, and humid areas of various climatic conditions.
2. The ship is far away from land for a long time, so the safety and reliability of the cable are very high, such as good electrical performance, stability, and no delay. The cables laid in some compartments require good oil resistance.
3. Small space inside the ship, strict requirements for cable outer diameter and outer diameter tolerance. For easy installation, the cable is required to be soft. In certain compartments (such as the main engine, and boiler compartment), the temperature is as high as 45-55 ℃, with some high humidity of more than 95%, requiring the cable heat-resistant, moisture-proof, mold resistance good.
4. When the cable is installed or moved, the tension is generally greater than on land and susceptible to external forces such as scraping and rubbing, requiring good mechanical properties. The cable on the deck, mast requires resistance to sunlight, atmosphere, and seawater pouring corrosion.
5. Part of the cable requires the ability to prevent interference.
6. Marine wire and cable flame retardant, fire-resistant requirements are particularly strict.
Executive standard: GB9331.2-88
Use: This product is suitable for various river and sea vessels and offshore oil platforms and other water buildings to transmit electrical energy.
Use Characteristics
The long-term allowable working temperature of the cable is 85℃, and the rated voltage Uo/U is 0.6/1KV. When laying, the bending radius of the cable is as follows: metal shield armored type is 6 times the outer diameter of the cable. For the non-armored type, 4 times the cable outer diameter when the outer diameter is less than or equal to 25mm, 6 times the cable outer diameter when it is larger than 25mm.
Model name: CEFR/DA Ethylene propylene insulated neoprene sheathed marine power flexible cable, type DA, for connecting mobile electrical appliances.
Technical Requirements
1. It should be able to withstand 30,000 curve tests in one trip.
2. The cable should be able to withstand AC voltage 3500V or DC 8400V, 5min without breakdown.
3. The cable core structure, insulation resistance, insulation, and sheath thickness and weight shall conform to the provisions of GB9331.2-88.
Delivery Requirements
1. Delivery length of three cores and below and conductor cross-section not greater than 2.5 square, should not be less than 150 meters, other cables 100 meters.
2. Delivery of short sections of cables of length not less than 20 meters, but their number should not exceed 10% of the delivery length.
3. Any length of cable delivery is allowed by mutual agreement.
4. The error shall be no more than +-0.5%.
