Why do ships have cables tied to their bodies? What is their purpose?

Introduction: Why do ships have to be covered with cables when they go to sea? What is their use? After reading this, I gained more knowledge

We know that ships are a very beneficial strategic tool at sea. They can not only greatly reverse the situation at sea, but also have multiple functions in one, and can be used in our vast territory. It defends our homeland on the sea and also plays an indispensable role in modern warfare. Our country has mastered the important technology of making large ships. These ships will be sent to our country’s waters for long-term cruises, and We will find in various news that these ships that have been cruising for a long time are covered with cables, and these cables do not seem to be of any benefit to their market performance, so why are they wrapped with these seemingly obstructive cables?

Some friends think that doing so will affect the appearance of the ship and make the ship lose its true character. However, it is not tied in for beauty or decoration. It is also a kind of helplessness. Because when a ship travels for a long time, it will generate friction with the air and form a magnetic field. These magnetic fields will not only affect the ship itself, but may also expose the ship's targets at sea.

The reason why many cables are tied to the outside of it is because these magnetic fields will have adverse reactions to various instruments and equipment on the ship itself, and may even cause damage in severe cases. It will cause these internal parts to fail to work properly, which is very dangerous for these ships performing missions. Secondly, if these ships themselves carry a large number of magnetic fields and some enemy weapons during a war, It is possible to track the movements of these ships based on this magnetic field, and launch torpedoes to accurately hit these ships. This is especially true for submarines with extremely powerful reconnaissance capabilities, which is why these ships are equipped with electricity to eliminate the magnetic field in this way.

Now after being powered on, the currents it generates will destroy the magnetic field problem caused by friction. Although this method is very cumbersome and backward, it is very effective when the ship is traveling overseas. In addition, another method is to use special degaussing equipment to degauss the ship as a whole when it docks at the port.

Although this method for the ship not only looks bulky but also unsightly, it is in order for the ship to better complete its tasks during the voyage, and at the same time to ensure that it does not slip during the voyage. Affected by other ships, and also to maintain the safety of the ship and all staff on the ship, this measure is still very necessary, and it must be implemented resolutely even if it is very troublesome.

It took him 24 years to make China's manufacturing world-class, and he is a leader in private heavy industry, comparable to Ren Zhengfei

Introduction: It took him 24 years to make China's manufacturing world-class, and he is a leader in private heavy industry. Leaders in heavy industry, on par with Ren Zhengfei

When it comes to various domestic entrepreneurs, the first thing that may come to everyone's mind is some real estate industry, or some automobile industry or Internet industry Giants, these people usually have a very high exposure, and they often appear in our lives. After all, people always want to shop online and get in touch with new things. And for some leaders in the heavy industry, Maybe everyone is not so impressed with them. When mentioning some very outstanding and outstanding private entrepreneurs in China, the first person that may come to many people's minds is a man named Ren Zhengfei. However, in addition to him, there is another person who must be mentioned, that is, the leader of China's private heavy industry, the founder of Sany Heavy Industry, his name is Liang Wengen.

When it comes to Liang Wengen, most people may not be familiar with how he developed heavy industry. In fact, it only took him more than 20 years to make this heavy industry enterprise a domestic At the beginning, Sany Heavy Industry was just a small factory in a small village. Over the past few decades, it has gradually developed into a very famous mechanical engineering manufacturing factory ranked first in China and one of the top ten in the world. In the first few quarters of this year, this heavy industry company has achieved revenue of more than 40 billion yuan, and profits have reached nearly 5 billion yuan, a year-on-year increase of more than 170%.

Although this company was just a small factory established in the countryside at the beginning, he regarded serving the country through industry as one of his biggest aspirations and goals, and used his passion and feelings to enable this heavy industry company to continue to achieve its goals. Breakthrough, and finally be able to enter the international market and conquer it with our own technology.

Liang Wengen was originally born in a mountain village in Hunan. His studies were not very good, so even after the college entrance examination system was restored, he spent two times, and finally I was admitted to a college to study materials science. A few years later, he was assigned to work in a local machinery factory. By around 1986, he had done an excellent job, but he and several colleagues were not satisfied with the status quo and hoped to use their own He wanted to work hard to build an excellent company, so he gave up a good opportunity to work in a state-owned enterprise and borrowed money from relatives to open a welding materials factory.

In the beginning, the business of the material factory was very mediocre, and others were not optimistic about it. Some people even called the material factory a canteen. However, Liang Wengen did not care about other people's opinions at all, and he The words that inspired them were made into slogans and hung in the factory, so these young people began to develop their own businesses. In just three years, the small factory at the beginning turned into a large factory, and the annual income exceeded 1,000. Ten thousand yuan. Later, it started from this small factory and eventually developed into an excellent heavy industry enterprise that uses its own technology to conduct core research and development and also develops overseas.
