1、 Execution standard: GB9331.2-88
2、 Usage: This product is suitable for transmitting electrical energy to various water structures such as river and sea vessels and offshore oil platforms.
3、 Usage 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 small bending radius of the cable is as follows: the metal shielding armor type is 6 times the outer diameter of the cable. Non armored type, when the outer diameter is less than or equal to 25mm, it is 4 times the outer diameter of the cable, and when it is greater than 25mm, it is 6 times the outer diameter of the cable.

1) Used for power, lighting, and control cables in river and sea vessels as well as floating structures on water. The working voltage is AC 500V or DC 1000V or below

（2) Soft structure cables are used to connect mobile electrical equipment, while the rest are fixedly laid

（3) Steel wire braided cables are used in places that are susceptible to external damage. Copper wire braided cables are used in places with anti-interference capabilities

（4) All cables can be used in places where non extension is required

Requirements for the use of marine cables:

（1) The cable should meet the requirements of various climatic conditions around the world and be able to withstand various climatic conditions in cold, dry, and humid regions.

（2) Ships that are far away from land for a long time have high requirements for the safety and reliability of cables, such as good electrical performance, stability, and no delay. Cables laid in certain cabins require good oil resistance.

（3) The space inside the ship is small, and strict requirements are placed on the outer diameter and outer diameter tolerance of the cables. For ease of installation, it is required that the cable be flexible. Some cabins (such as main engine and boiler cabins) have temperatures as high as 45-55 degrees Celsius and humidity levels as high as 95% or higher, requiring cables to have good heat resistance, moisture resistance, and mold resistance.

（4) When installing or moving cables, the tension is generally greater than on land, and they are susceptible to external forces such as scraping and rubbing, requiring good mechanical performance. The cables on the deck and mast are required to withstand the erosion of sunlight, atmosphere, and seawater.

（5) Some cables require anti-interference capabilities.

（6) The flame retardancy and fire resistance requirements for marine wires and cables are particularly strict.
