A few days ago, the first domestic shipborne submarine cable electric pallet put into operation, it is reported that the technology by Zhoushan Qiming Power Construction Company began to develop in 2012, the maximum bearing capacity of 2,000 tons, diameter 18 meters, can use computer control stepless speed change, the successful development of this technology represents a further simplification
of the difficulty of submarine cable laying.
Submarine cables are divided into submarine communication cables and submarine power cables
.
Submarine communication cables are mainly used for communication business, which is expensive but has a high
degree of confidentiality.
Submarine power cables are mainly used for underwater transmission of high-power electric energy, which is equivalent to the role of underground power cables, but the application occasions and laying methods are different
.
Because the submarine cable project is recognized by the world as a complex and difficult large-scale project, from environmental exploration, marine physical survey, and cable design, manufacture and installation, are the application of complex technology, so submarine cable manufacturers in the world is one of the few, mainly Norway, Denmark, Japan, Canada, the United States, Britain, France, Italy and other countries, these countries in addition to manufacturing also provide laying technology
.
At present, the submarine power cables applied in China still need to be imported

.
In the past, submarine cable laying adopts pump-up construction, but with the increase of large-diameter, high-voltage submarine cables, the pump-up construction method is easy to cause the expansion of submarine cable armor and even insulation damage
due to stress factors.
Now the rotary electric pallet is used, which can not only eliminate the internal stress of the submarine cable, but also increase the safety factor
of the submarine cable construction vessel.
Submarine cables are wires wrapped in insulating material and laid under the sea floor and rivers for telecommunications transmission
.
Modern submarine cables use optical fiber as a material to transmit telephone and Internet signals
.
The world's first submarine cable was laid between Britain and France in 1850
.
China's first submarine cable was completed in 1888 and has two, one between Chuanshi Island in Fuzhou and Huwei (Tamsui) in Taiwan, which is 177 nautical miles long, and the other from Anping, Tainan to Penghu, which is 53 nautical miles
long.
