Classification of Marine cables
Classification of Marine cables
From the point of use, it can be divided into marine power cables used for power equipment, lighting, and control equipment; their functions are marine power cables: are used for various ships in rivers and seas and offshore oil platforms. , lighting use
Marine control cable: used for general control of various ships in rivers and seas and offshore oil platforms and other water structures
Marine communication cables: used for signal transmission and control systems in various ship communications, electronic computers, and information p
rocessing equipment.
Marine communication cables for telephones and certain electronic equipment; marine twisted pair telephone cables for marine telephones and broadcasting; marine radio frequency cables for transmitting radio frequency currents for ships; marine use for transmitting asymmetric high-frequency signals to the ground coaxial cable.
According to the number of core wires, it can be divided into marine single-core cable, marine three-core cable, and marine multi-core cable. According to the conditions of use, it can be divided into ordinary cable, floating cable, watertight cable, extra soft cable, and signal buoy cable.
The insulating material, can be divided into ordinary rubber insulated cable, butyl rubber insulated cable, ethylene propylene rubber insulated cable, PVC insulated cable, and silicone rubber insulated cable.
The sheath material, can be divided into neoprene sheathed marine cable, polyethylene sheathed marine cable, and vulcanized butyl sheathed marine cable. Metal armor with steel wire braid and copper wire braid.
In order to prevent the fire from spreading due to the burning of the cable, or the generation of harmful gas, which can cause people to suffocate and die, there are also flame-retardant and low-smoke, and low-toxic marine cables. The marine cables have good electrical, mechanical, aging resistance, moisture resistance, oil resistance and cold resistance, etc. performance, and good flexibility.
